Wilmington, North Carolina 28403
Tel [phone]
NC Firm License No. C-2586
Per your additional information request letter to PCS Phosphate Company, Inc., dated October 6, 2021,
we have prepared a minor permit modification application package for the addition of a BOD supplement
to the PCS Phosphate wastewater treatment plant.
PCS Phosphate Company began a series of studies starting in 1998 to improve the quality of the effluent
from its onsite wastewater treatment plant (WWTP). The existing plant serviced approximately 1,500
personnel until a reduction in force in 2011 to approximately 800. Between this reduction in personnel
and the onsite cafeteria closing in 2016, the WWTP has experienced fluctuations in biochemical oxygen
demand (BOD) impacting the food to mass ratio required for the biological treatment of its wastewater.
To stabilize these fluctuations, operations began adding supplementary BOD in the form of MicroC 2000.
MicroC 2000 is a proprietary, non -hazardous BOD supplement designed specifically to be used as a
carbon source for biological wastewater treatment. It comes in concentrated liquid form and is dosed
into the influent to assist with maintaining the treatment system appropriate food to mass ratio. The
following minor permit modification has been prepared to include this BOD supplement.
Please find enclosed the following documents for your review and approval:
1. One (1) original two (2) copies of application form —13 pages each
2. Three (3) copies of North Carolina Secretary of State Business Registration documentation — 2
pages each
3. Three (3) copies of the property ownership deed — 3 pages each
4. Three (3) copies of the existing High -Rate Infiltration System Permit #WQ0000889 —18 pages
each
5. Three (3) copies of the sealed feed addition calculations —1 page each
6. Three (3) copies of the feed addition site plan drawing —1 page each
Engineering is our profession. Service is our passion.

7. Three (3) copies of the Engineering Certification —1 page each
8. Three (3) copies of the Nutrient Supplemental Feed System Components List — 1 page each
9. Three (3) copies of the Premia 75 Specifications — 55 pages each

INTRODUCTION
DESCRIPTION
These installation, operation and maintenance instructions cover your
electronic metering pump. Refer to the pump nameplate to determine the
actual model.
Diaphragm metering pumps are used to dispense chemicals or fluids. This
is achieved by an electromagnetic drive mechanism (solenoid), which is
connected to a diaphragm. When the solenoid is pulsed by the control
circuit, itdisplaces the diaphragm, which, through the use ofcheckvalves,
moves the fluid out the discharge under pressure. When the solenoid is
deenergized, it returns the diaphragm and pulls more fluid into the pump
head and the cycle repeats.
The pump stroke rate is controlled by the internal circuit and is changed
by turning the rate knob. The mechanical stroke length of the pump is
controlled by the stroke length knob.

GENERAL SAFETY CONSIDERATIONS
• Always wear protective clothing, including gloves and safety glasses,
when working on or near chemical metering pumps.
• Inspect tubing regularly for cracking or deterioration and replace as
necessary (when replenishing chemical solution). Always wear pro-
tective clothing and safety glasses when inspecting tubing.
• When pump is exposed to direct sunlight, use U.V -resistant tubing.
• Follow the directions and warnings provided with the chemicals from
the chemical manufacturer. The customer is responsible for deter-
mining chemical compatibility with the chemical feed pump.
• Secure chemicals and metering pumps, making them inaccessible to
children and pets.
• Make sure voltage on chemical metering pump matches the voltage
at the installation.
• Do not cut plug off of electrical cord or the ground lug —consult a
licensed electrician for proper installation.
• Pump is NOT to be used to handle flammable liquids.
SAFE OPERATING PROCEDURES
CAUTION: All pumps are tested with water before shipment. Re-
move head and dry thoroughly if you are pumping chemical that will
react with water (i.e., sulfuric acid). Valve seats, ball checks, gaskets,
and the diaphragm should also be dried.
• Finger -tighten connections on pump head. DO NOT USE A
WRENCH. Teflon tape is necessary only when pump is equipped
with NPT connections.
• Before repairing or moving pump, disconnect power cord or turn off
power to pump. De -pressurize system and drain chemical. (Always
wear protective clothing and safety glasses when working on
metering pump.)
• Always consult licensed plumber and electrician before installation,
and make sure to conform to local codes.
• Consult with local health officials and a qualified water conditioning
specialist when treating potable water.
• Be sure to de -pressurize system prior to hook-up or disconnection of
metering pump.
• If point of injection is lower than chemical tank and pump, install an
anti -syphon valve.
• DO NOT MODIFY pump, this poses a potentially dangerous situa-
tion and voids warranty.
• For accurate volume output, pump must be calibrated under all op-
erating conditions.

PREMIATm 75 MEGA
1.1 Materials of Construction
The wetted materials (those parts that contact the solution being pumped)
available for construction are glass -filled polypropylene, PVC, SAN,
Hypalon, Viton, Teflon, 316 Stainless Steel, PVDF, Ceramic, and Alloy
C. These materials are very resistant to most chemicals; however, there
are some chemicals, such as strong acids or organic solvents, that cause
deterioration of some elastomer and plastic parts, such as the diaphragm,
the valve seat, or the head. Consult the Chemical Resistance Guide or your
chemical supplier for information on chemical compatibility.
Various manufacturers of plastics, elastomers, and pumping equipment
publish guidelines that aid in the selection of wetted materials for pump-
ing commercially available chemicals and chemical compounds. Two
factors must always be considered when using an elastomer or plastic part
to pump chemicals:
• The temperature of service: Higher temperatures increase the effect
of chemicals on wetted materials. The increase varies with the mate-
rial and the chemical being used. A material quite stable at room
temperature might be affected at higher temperatures.
• Material choice: Materials with similar properties may differ greatly
from one another in performance when exposed to certain chemi-
cals.
1.2 Manufacturer's Product Warranty
The manufacturer warrants its equipment of its manufacture to be free of
defects in material or workmanship. Liability under this policy extends
for 18 months from the date of purchase or one year from date of instal-
lation, or whichever comes first. The manufacturer's liability is limited to
repair or replacement of any device or part that is returned, prepaid, to the
factory and that is proven defective upon examination. This warranty
does not include installation or repair cost and in no event shall the
manufacturer's liability exceed its selling price of such part.
The manufacturer disclaims all liability for damage to its products through
improper installation, maintenance, use, or attempts to operate such prod-
ucts beyond their functional capacity, intentionally or otherwise, or any
unauthorized repair. Replaceable elastomeric parts are expendable and
are not covered by any warranty, either expressed or implied. The manu-
facturer is not responsible for consequential or other damages, injuries, or
expense incurred through use of its products.
IM 460.150AE UA (A/2-96) 2

PREMIATm 75 MEGA
The above warranty is in lieu of any other warranty, either expressed or
implied. The manufacturer makes no warranty of fitness or merchantabil-
ity. No agent of ours is authorized to make any warranty other than the
above.
1.3 Unpacking the Pump
Check all equipment for completeness against the order and for any evi-
dence of shipping damage. Shortages or damages should be reported
immediately to the carrier and to the seller of the equipment.
The carton should contain:
• Metering Pump
• Clear Flexible Suction Tubing
• Stiff White Discharge Tubing
• Foot valve/Strainer Assembly
• Backpressure Injection Valve Assembly
• One Instruction Book
• Five -Function Valve (most models)
• Tube Wand (most models)
Make sure that all items have been removed from the shipping carton
before it is discarded.
1.4 Precautions for Operation
Each Electronic Metering Pump has been tested to meet prescribed speci-
fications and safety standards. Proper care in handling, installation, and
operation will help in ensuring a trouble -free installation.
Please read all these cautionary notes prior to installation and start-up of
your metering pump.
• Pump must be installed and used with supplied back pressure/injec-
tion valve. Failure to do so could result in excessive pump output
flow.
• Handle the pump with care. Dropping or heavy impact causes not
only external damage to the pump, but also to electrical parts inside.
• Install the pump in a place where the ambient temperature does not
exceed 1040F (400C). The pump is water-resistant and dust -proof by
construction and can be used outdoors; however, do not operate the
IM 460.150AE UA (A/2-96) 3

PREMIATm 75 MEGA
pump submerged. To avoid high internal pump temperatures, do not
operate in direct sunlight.
Install the pump in a place convenient for its future maintenance and
inspection, then fix it to prevent vibration.
• Protective caps must be removed prior to installing tubing onto valve
assemblies. Use tubing of specified size. Connect the tubing to the
suction side securely to prevent the entrance of outside air. Make
sure that there is no liquid leakage on the discharge side.
Be careful to check that the voltage of the installation matches the
voltage indicated on the pump nameplate. Each pump is equipped
with a three -prong plug. Always be sure the pump is grounded. To
disconnect, do not pull wire, but grip the plug with fingers and pull
out. Do not use the receptacle in common with heavy electrical equip-
ment that generates surge voltage. This can cause the failure of the
electronic circuit inside the pump.
Tampering with electrical devices can be potentially hazardous. Al-
ways place chemicals and pump installation well out of the reach of
children.
Q WARNING: NEVER REPAIR OR MOVE THE METERING PUMP
WHILE OPERATING. ALWAYS DISCONNECT ELECTRICAL
POWER. FOR SAFETY, ALWAYS WEAR PROTECTIVE
CLOTHING (PROTECTIVE GLOVES AND SAFETY GLASSES)
WHEN WORKING ON OR NEAR CHEMICAL METERING
PUMPS.
An air bleed valve is available for most models with tubing connec-
tions. Air purges should be performed when the pump chamber con-
tains no fluid at the time of start-up. As a safety measure, connect the
return tubing to the air bleed valve and bypass fluid back to storage
tank or a suitable drain.
Chemicals used may be dangerous and should be used carefully and
according to warnings on the label. Follow the directions given with
each type of chemical. Do not assume chemicals are the same be-
cause they look alike. Always store chemicals in a safe location away
from children and others. USF/W&T cannot be responsible for the
misuse of chemicals being fed by the pump. Always have the mate-
rial safety data sheet (MSDS) available for any fluid being pumped.
IM 460.150AE UA (A/2-96)

PREMIATm 75 MEGA
Q WARNING: TO PREVENT SEVERE PERSONAL INJURY, RE-
FER TO THE MSDS FOR THE MATERIAL BEING HANDLED.
CAUTION: All pumps are pre -tested with water before shipment.
Remove head and dry thoroughly if you are pumping a material that
J/Ne
will react with water (i.e., sulfuric acid, polymers). Valve seats, ball
checks, gaskets, and the diaphragm should also be dried. Before plac-
ing pump into service, extreme care should be taken to follow this
procedure.
Valve cartridges are stamped to indicate fluid flow direction. Always
install so that markings read from top to bottom, and the arrow points
in the direction of flow.
When metering hazardous material, DO NOT use plastic tubing, use
proper rigid pipe only. Consult supplier for special adapters or valve
assemblies.
Q WARNING: PUMP IS NOT TO BE USED TO HANDLE OR METER
FLAMMABLE LIQUIDS OR MATERIALS.
• Standard white discharge tubing is not recommended for installa-
tions exposed to direct sunlight. Consult supplier for special black
tubing.
• USF/W&T will not be held responsible for improper installation of
pump or for plumbing. All cautions are to be read thoroughly prior to
hook-up and plumbing. For all installations, a professional plumber
should be consulted. Always adhere to local plumbing codes and
requirements.
When using pump with pressurized systems, make sure the pressure
of the system does not exceed the maximum pressure rating on the
pump nameplate. Be sure to de -pressurize the system prior to hook
up or disconnecting the metering pump.
Electronic power modules are equipped with automatic reset ther-
mal overload devices and may reset unexpectedly.
The pump is designed to operate using a backpressure/injection valve.
If the discharge point is below the liquid level of the source or if the
discharge pressure is less than the suction pressure, syphoning may
occur. To correct this condition, install an anti -syphon valve or other
anti -syphon device. Check local regulations that may apply. (Refer
to Figure 2.3.)

2.1 Introduction
2.2 Mounting
The metering pump should be located in an area that allows convenient
connections to both the chemical storage tank and the point of injection.
The pump is water-resistant and dust -proof by construction and can be
used outdoors; however, do not operate submerged. Avoid continuous
temperatures in excess of 104°F (40°C). To do otherwise could result in
damage to the pump.
Typical mounting arrangements are shown in Figures 2.1(A), (B), (C),
and (D).
NOTE: The injection point must be higher than the top of the solution
supply tank to prohibit gravity feeding, unless a suitable backpressure
is always present at the injection point.

For wall or shelf mounting, refer to Figure 2.1(A). Connect suction
tubing to suction valve of chemical pump. Suction valve is the lower
valve. Tubing should be long enough so that the foot valve/strainer
assembly hangs about two to three inches above the bottom of chemi-
cal tank. To keep the chemical from being contaminated, the tank
should have a cover.
Flooded suction mounting (installing the pump at the base of the
chemical storage tank, as shown in Figure 2.1(B)) is the most trouble -
free type of installation and is recommended for very low output re-
quirements. Since the suction tubing is filled with chemical, priming
is accomplished quickly and the chance of losing prime is reduced.
To mount the pump, drill four holes of 1/4-inch diameter in the shelf
as shown in the dimension drawing (Figure 2.2). Attach pump se-
curely using four 910 bolts and nuts.

The pump can be mounted to a wall, as shown in Figure 2.1(C). A
wall -mount bracket kit is available that includes all necessary hard-
ware to mount the pump to the wall. Mounting the pump other than
as shown in Figure 2.1(C) defeats the purpose of the housing drain.
Mounting dimensions for the pump are provided in Figure 2.2 for
reference.
The pump can be mounted on top of a solution tank as shown in
Figure 2.1(D). Install the chemical pump on the cover. Insert suction
tubing through the center hole and cut tubing so the foot valve/strainer
hangs about two or three inches above the bottom of the tank. Mount
the chemical pump rigidly by drilling four 1/4-inch holes and using
our 910 screws and nuts.
• USE AN ANTI -SYPHON VALVE IN THE DISCHARGE LINE
whenever the fluid pressure in the discharge line is below atmospheric
pressure. This can occur if the injection point is on the suction side
of a water pump or against a "negative" head, such as when feeding
down into a well (see Figure 2.3).

2.3 Piping
• Use provided tubing of specified size for connection. Connect tub-
ing securely to prevent leakage of chemical and the entrance of air.
Since plastic nuts are used for fittings, they should not be tightened
excessively i.e. hand tighten only. NPT suction and discharge valves
must NOT be over -tightened. Hold fittings in place while adding
piping and fittings. NPT suction and discharge valves should only be
tightened 25 to 35 in. lbs.
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL IN-
JURY, DO NOT USE HOSE OR OTHER FLEXIBLE TUBING FOR
THE DISCHARGE LINE WHEN PUMPING HAZARDOUS MA-
TERIALS OR FOR DISCHARGE PRESSURE OR FLUID TEM-
PERATURE IN EXCESS OF THE LISTED MAXIMUM RATINGS.
ALWAYS USE RIGID PIPE FOR THOSE CONDITIONS.
• If the air bleed valve assembly is being used, a return line (tubing)
should be securely connected and routed back to the storage tank.

PREMIATm 75 MEGA
• When the pump is shelf -mounted or top -mounted on the tank, suc-
tion tubing should kept as short as possible. Pumps mounted on or
above a tank should use the tube wand to ensure that the foot valve/
strainer remains in a vertical position. The vertical position is critical
to proper foot valve performance. To assemble, alternating large and
small diameter sections are inserted one to two inches and twisted to
lock in place. The tubes are telescoped to varying lengths to match
the tank (maximum length is 36 inches). Feed the suction tubing
through the tube wand until it extends beyond the end of the tube
wand. Do not kink suction tubing. Attach foot valve/strainer to suc-
tion tubing. Install suction tubing with tube wand and foot valve/
strainer into tank. Adjust length of suction tubing to hold foot valve/
strainer approximately two inches from the bottom of the tank (see
Figure 2.4). Connect suction tubing to the suction side of the pump.

• To maintain metering performance, a back pressure/injection valve
is provided. The injection valve must be installed in the discharge
line. The best practice is to install the injection valve at the point of
chemical injection.
• If the discharge tubing is going to be exposed to direct sunlight, black
tubing should be used instead of the standard white translucent tub-
ing supplied with each pump. To obtain this tubing, contact your
supplier.
• To prevent clogging or check valve malfunction, always install a
strainer assembly to the end of the suction tubing (see Figure 2.1(D)).
IM 460.150AE UA (A/2-96) 11

PREMIATm 75 MEGA
This foot valve/strainer assembly should always be installed two to
three inches above the bottom of the chemical tank. This will help
prevent clogging the strainer with any solids that may settle on the
tank bottom. The chemical tank and foot valve/strainer should be
cleaned regularly to ensure continuous trouble -free operation. If the
chemical being pumped regularly precipitates out of solution or does
not dissolve easily or completely (e.g., calcium hydroxide), a mixer
should be used in the chemical tank. These are readily available in
many motor configurations and mountings. To obtain a mixer, con-
tact your supplier.
A flooded suction (tank liquid level always at a higher elevation than
the pump) is recommended when pumping sodium hypochlorite
(NaOCI) and hydrazine solution (NZHZ), etc., which are liable to pro-
duce air bubbles. Maintaining a low liquid temperature will also help
eliminate this problem.
Pipe corrosion can result if dilution at the injection point does not
occur rapidly. This problem is easily prevented by observing this
simple rule: install injection fitting so that the end is in the center of
the flow stream of the line being treated. Trim injector tip as required.
See Figure 2.5.

NOTE: Extended injection assemblies are available for large water
lines. Consult your supplier for more information.

Wiring
• The metering pump should be wired to an electrical source that con-
forms to those on the pump nameplate. (Applying a higher voltage
than the pump is rated for will damage the internal circuit.)
Q WARNING: RISK OF ELECTRICAL SHOCK. THIS PUMP IS
SUPPLIED WITH A THREE -PRONG, GROUNDING -TYPE
POWER PLUG. TO REDUCE RISK OF ELECTRIC SHOCK,
CONNECT ONLY TO A PROPERLY GROUNDED, GROUND-
ING -TYPE RECEPTACLE.
NOTE: Field wiring must confirm to local electrical codes.
In the electronic circuit of the control unit, measures for surge volt-
age are made by means of surge absorbing elements and high volt-
age semiconductors. Nevertheless, excessive surge voltage may cause
failure in some areas. Therefore, the receptacle should not be used in
common with heavy electrical equipment which generates high volt-
age. If this is unavoidable, however, measures should be taken by
the installation of a surge absorbing element (varister of minimum
surge resistance 2000A) to the power supply connection of the pump
(see Figure 2.6(A), or the installation of a noise suppression trans-
former (see Figure 2.6(13)).

3.1 Power
All metering pumps are available in 115 volts at 50/60 Hertz, single-
phase. Optionally, 230 volts at 50/60 Hertz, single-phase can be provided.
Prior to start-up, always check that the pump voltage/frequency/phase
matches that of the power supply.
Q CAUTION: If the pump is fitted with a PVC pump head (fifth posi-
tion of model number is "V"—PVC is gray, not black), uniformly
hand -tighten the four head screws before use (18 to 22 in./lbs). Peri-
odically tighten after installation.
3.1.1 Start Up and Shut Down
• To start pump, turn on power.
• To shut down or stop pump, turn off power.
3.2 Priming
Q WARNING: WHEN WORKING ON OR AROUND A CHEMICAL
METERING PUMP INSTALLATION, PROTECTIVE CLOTH-
ING, GLOVES, AND SAFETY GLASSES SHOULD BE WORN AT
ALL TIMES.
Q WARNING: ALL PUMPS ARE TESTED WITH WATER. IF THE
CHEMICAL TO BE PUMPED REACTS WHEN MIXED WITH
WATER (E.G., SULFURIC ACID, POLYMER), THE PUMP HEAD
SHOULD BE REMOVED AND DRIED THOROUGHLY ALONG
WITH THE DIAPHRAGM AND VALVE SEATS.
Turn on the power to the pump. The green LED will light up and
flash off each time the pump strokes.
b. Adjust the stroke rate knob to the 100% setting mark. (Refer to para-
graph 3.4, Capacity Control, for more information.)
c. Adjust the stroke length knob to the 100% setting mark. (Refer to
paragraph 3.4, Capacity Control, for more information)
d. If the discharge line is connected directly to a pressurized system, it
should be temporarily bypassed during priming of the pump. A bleed
valve will simplify this operation by allowing easy bypass of the
discharge fluid. All air must be purged from the pump head before
the pump will pump against pressure. (Refer to paragraph 3.3, Air
Bleed Operation, for more information.)
IM 460.150AE UA (A/2-96) 18

e. Chemical should reach the pump head after a few minutes of opera-
tion. If not, remove the discharge fitting and moisten the discharge
valve area (ball check and valve seats) with a few drops of the chemi-
cal being fed to the metering pump.
f. If the pump continues to refuse to prime, refer to paragraph ??,
Troubleshooting.
g. Once the pump has been primed and is pumping the chemical through
the head, turn off the power, reconnect the discharge tubing (if it had
been removed), and immediately clean any spilled chemical that is
on the pump housing or head.
h. Turn the power on once more and adjust the pump flow to the de-
sired rate (see paragraph 3.4, Capacity Control).
i. Always check the calibration of the pump after start-up. It is best to
calibrate the pump under your typical use conditions.
3.3 Air Bleed Operation (See Figure 3.1)
a. While the pump is running, turn the bottom knob to the "D" position,
also labeled "BLEED".
b. Run the pump with the valve open until a solid stream of fluid comes
out of the bypass tubing (1/4 x 3/8 supplied with valve), and there
are no air bubbles.
c. Close air bleed valve by turning bottom knob to position "C", also
labeled "PUMP".

3.4 Capacity Control
Capacity can be controlled by means of the stroke length adjusting knob
or stroke frequency adjusting knob. Control knobs provide coarse adjust-
ment, use a calibration column for accurate calibration. Contact your
pump supplier for proper calibration equipment.
3.4.1 Stroke Frequency Adjustment (See Figure 3.2)
Stroke frequency can be controlled from 10 to 100% (12 to 125 spm) by
means of the electronic circuit.
The frequency can be set by means of the stroke frequency adjusting knob,
even while the pump is in operation.

Controlling Procedure
Proper set points for stroke length and stroke frequency should be deter-
mined after consideration of the pump and characteristics of the fluid. The
following procedure is recommended from the viewpoint of pump perfor-
mance.
NOTE: The closer the stroke length is to 100%, the better the pump
performance will be.
a. Set the stroke length to 100%, then adjust the stroke frequency for
coarse capacity control.
b. Measure the capacity.
c. When the measured capacity is less than the required value, increase
the stroke frequency and measure the capacity again.
d. Adjust the stroke length for fine capacity control.
e. Measure the capacity and make sure that the required value is ob-
tained.
Example
Set Stroke Length = 100%
Set Stroke Rate = 100%
Output Capacity = 21 GPD*
(Rated Pressure)
Desired Flow = 15 GPD
Adjust Stroke Rate to 80%
Output Capacity = 0.80 x 21 = 16.8 GPD*
Stroke Length Setting = 15 x 100 = 90% approx
16.8
To obtain the desired flow, stroke length is set at 90% and stroke rate
is set at 80% (i.e., output capacity = 0.90 x 0.80 x 21 = 15 GPD*).
* Check these values by measurement. Output capacity is higher when
feeding against less than rated pressure.

PREMIATm 75 MEGA
3.5 Operation by External Input Signals
3.5.1 Stop Function
The pump can be controlled by three types of input signals. All are fully
isolated from AC input power and from earth ground. The input socket
connections are located at the bottom of the control panel face and the
signal cords are provided with the pump. Remove rubber plugs to access
the plug sockets.
Operation of the pump can be stopped by an external signal input. When
the external signal is input to the terminal marked "STOP", which is
provided at the bottom of the control panel, the (red) lamp lights up and
operation of the pump is stopped. The STOP function overrides both
manual settings and external input signals at other terminals.
Q CAUTION: Operation of more than one pump from the same contact
closure will damage the pump circuits. When such operation is re-
quired, the pump circuits must be electrically isolated from one an-
other by means of a multi -contact control relay or similar means.
Input signals should be no -voltage signals from relay contacts, etc., and
the input of other signals is prohibited. (In case of relay contacts, electric
resistance must be 100 ohms or less at ON, and IM ohm or more at OFF).
The STOP function is commonly used in conjunction with a tank float
switch. The float switch contacts are normally open, but, when the tank
level falls past a certain point, the contacts close and the pump stops.
3.5.2 External Pacing Function
The pump's stroke rate can be controlled by an external input signal. When
the input signal line is connected and the EXTERNAL/OFF/MANUAL
switch is in the external position and a contact signal is input to the termi-
nal marked "EXTERNAL" the pump makes one discharge stroke.
Q CAUTION: Operation of more than one pump from the same contact
closure will damage the pump circuits. When such operation is re-
quired, the pump circuits must be electrically isolated from one an-
other by means of a multi -contact control relay or similar means.
When the "ON" signal pulse is input, the pump operates one stroke and
the fluid is discharged. In addition, the pump can be operated continu-
ously at a rate of up to 125 strokes/minute by repeated input of "ON" and
"OFF" signals.
IM 460.150AE UA (A/2-96) 22

PREMIATm 75 MEGA
After receiving an input signal, the pump generates the necessary power
pulse to actuate the solenoid. The external signal input is debounced by
the pump circuit. The pump will not stroke in response to a spurious or
erratic input signal that follows at a rate greater than 125 spm. If the
external signal rate exceeds 125 spm, the pump will stroke at half the
external signal rate to prevent overdosing and to protect the pump from
overheating.
Input signals should be no -voltage signals from relay contacts, etc., and
the input of other signals is prohibited. (In the case of relay contacts,
electric resistance must be 100 ohms or less at ON, and IM ohms or more
at OFF).
Cycle rate of the input signal should not exceed 125 times/minute.
Typical wiring is shown in Figure 3.4 for use with switch closure
flowmeters.
Ten millisecond contact time is required for each "ON" input signal.
Figure 3.4
3.5.3 4-20 mA do Input Function
PLUG
The pump's stroke rate can also be controlled by a 4-20 mA DC signal
applied to the terminal marked "4-20 mA".
For the 4-20 input to have any effect on the pump output rate, the AUTO/
OFF/MANUAL switch must be in the AUTO position.
The 4-20 mA input signal affects the pump's outputs as per the graph in
Figure 3.5.

3.6 Five -Function Valve Operation
3.6.1 Pressure Relief Function
Designed to relieve excessive pump discharge pressure (approximately
50% above PRV rating). PRV is functional anytime the bottom control
knob is turned to the "C" position, also labeled "PUMP".
Color code for PRV rating:
Blue 100psi
Green 150 psi
Red 250 psi
IM 460.150AE UA (A/2-96) 24

PREMIATm 75 MEGA
3.6.2 Back Pressure Function
The back pressure function allows the pump to meter to atmosphere by
creating a discharge restriction of approximately 20 psi. Back pressure is
provided anytime the knob is turned to the "A" position, also labeled
"ON".
NOTE: The back pressure function is not intended to prevent
flowthrough from the elevated supply tanks. The pump -rated pres-
sure does not have to be de -rated when the back pressure knob is in
the "ON" position.
3.6.3 Anti -Syphon Function
The anti -syphon function prevents syphoning through the pump when
pumping to a receptacle lower than the pump. This feature is active when
the top knob is turned to the "A" position, also labeled "ON".
3.6.4 Pump Head Air Bleed Function
This function is used when starting the pump to aid in priming. It allows
for removal of air from the pump head by bypassing air and fluid out the
"RETURN" connection. This feature will function when the bottom knob
is turned to letter "D" position, also labeled "BLEED".
3.6.5 Discharge Drain Function
This function is used to depressurize the pump discharge line and/or drain
it. This function is accomplished by turning the top knob to the "B"
position, also labeled "OFF", and the bottom knob to the "D" position,
also labeled `BLEED". This will bypass discharge line fluid to the five -
function valve "RETURN" line.

Q WARNING: BEFORE PERFORMING ANY MAINTENANCE OR
REPAIRS ON CHEMICAL METERING PUMPS, BE SURE TO
DISCONNECT ALL ELECTRICAL CONNECTIONS AND EN-
SURE THAT ALL PRESSURE VALVES ARE SHUT OFF AND
PRESSURE IN THE PUMP AND LINES HAS BEEN BLED OFF.
Q WARNING: ALWAYS WEAR PROTECTIVE CLOTHING,
GLOVES, AND SAFETY GLASSES WHEN PERFORMING ANY
MAINTENANCE OR REPAIRS ON CHEMICAL METERING
PUMPS.
4.1 Routine Maintenance
Routinely check the physical operating condition of the pump. Look
for the presence of any abnormal noise, excessive vibration, low flow
and pressure output, or high temperatures (when running constantly
at maximum stroke rate, the pump housing temperature can be up to
160°F [70°C]).
For optimum performance, cartridge valves should be changed ev-
ery four to six months. Depending on the application, more frequent
changes may be required. Actual operating experience is the best
guide in this situation. Repeated short-term deterioration of valve
seats and balls usually indicates a need to review the suitability of
wetted materials selected for the application. Contact the supplier
for guidance.
Check for leaks around fittings or as a result of deteriorating tubing
(e.g., when standard white translucent discharge tubing is exposed
to direct sunlight). Take appropriate action to correct leak by tight-
ening fittings or replacing components.
• Keep the pump free of dirt/debris, as this provides insulation and can
lead to excessive pump temperatures.
If the pump has been out of service for a month or longer, clean the
pump head/valve assemblies by pumping fresh water for approxi-
mately 30 minutes. If the pump does not operate normally after this
"purging run," replace the cartridge valve assemblies.
IM 460.150AE UA (A/2-96) 28

PREMIATm 75 MEGA
4.2 Disassembly and Assembly
4.2.1 Diaphragm Removal
a. Flush pump head and valve assemblies out by running pump on wa-
ter or other suitable neutralizing solution. Wash outside of pump down
if chemical has dripped on pump.
b. Set stroke length of pump to 0% and unplug pump.
c. Disconnect tubing or piping from the pump. Remove the four pump
head screws and then remove the pump head assembly.
d. Remove the diaphragm by grasping it at the outer edges and turning
it counterclockwise until it unscrews from the electronic power mod-
ule (EPM). Do not lose the deflection plate or the diaphragm shims
that are behind the diaphragm.
NOTE: Shim quantity can be from none to three.
e. Inspect diaphragm if it is intended to be used again. Look for indica-
tions of the Teflon face being over -stretched (localized white areas)
or the elastomer on the back of the diaphragm being worn. Excessive
amounts of either condition require diaphragm replacement.
4.2.2 Diaphragm Replacement
Refer to drawings in the back of the manual.
NOTE: When replacing the diaphragm, it is always a good idea to
replace the valve cartridges and other worn parts. A kit is available
from your supplier with all parts necessary to completely rebuild
your pump's wet end. All your supplier needs to know to supply this
kit is the PM kit number on your pump's nameplate.
a. Set pump stroke length to 0% and unplug the pump.
b. If you kept the shims from the original diaphragm, or know the origi-
nal quantity, you can avoid step c for shimming the diaphragm and
go to step d.
c. Slide the diaphragm deflection plate onto the back of the diaphragm
stud, radius side toward the diaphragm. Next, slide three shims onto
the diaphragm threaded stud, and screw the diaphragm into the EPM
unit. Refer to Figure 4.1. Turn diaphragm clockwise until deflection

plate and shims are tight against solenoid shaft and the diaphragm
stops turning. If there is a gap between the adapter and the diaphragm,
repeat the procedure, removing one shim each time until the dia-
phragm just touches the adapter or is slightly recessed.

d. Apply grease to areas of the diaphragm that contact the deflection
plate or radius on the adapter.
e. Screw the diaphragm into the EPM unit's shaft with the deflection
plate and appropriate number of shims in between.
f. Adjust stroke length to 50%. It is easier to do this if you turn the
pump on temporarily. Place the pump head onto the adapter with the
valve flow arrows pointing up, and install and tighten the pump head
screws. Tighten the screws until the pump head pulls up against the
adapter.
g. Adjust stroke length back to 100% for easier priming and place pump
back into service.
4.2.3 Valve Replacement
a. Flush pump to clean any chemical from the pump head.
b. Unplug the pump, release system pressure, and disconnect any tub-
ing or piping.
c. Unscrew the valve cartridges and discard. Also remove 0-rings down
inside pump head.
IM 460.150AE UA (A/2-96) 30

PREMIATm 75 MEGA
d. Using new O-rings, install new valve cartridges with stamped letters
reading from top to bottom, and the arrow pointing in the direction
of flow. Hand -tighten only, do not use wrenches or pliers. This is
especially important when the pump head is SAN material.
e. Reconnect tubing or piping and reinstall the pump.
f. Check for leaks around newly installed fittings.
4.3 Five -Function Valve
4.4 Troubleshooting
The only maintenance required is to replace the diaphragms whenever the
pump head diaphragm is replaced. Sometimes when pumping dirty fluids,
solids may become trapped between the PRV diaphragm (bottom one)
and the PRV seat. This may cause the PRV to weep slightly. This is easily
remedied by removing the diaphragm, wiping it with a cloth, and rein-
stalling it. If the damage is excessive, the diaphragm will have to be
replaced.

SECTION 6 - PREVENTIVE MAINTENANCE KITS
SELECTING A PM KIT
The manufacturer has built a reputation for superior reliability by supply-
ing carefully designed, high -quality equipment. Even the best equipment,
however, requires a minimal amount of maintenance. PM kits are de-
signed to guard against unnecessary downtime and assure you the highest
level of efficient and uninterrupted service.
PM kits contain those recommended spare parts that will most likely
require normal maintenance.
A typical PM kit includes Valve Cartridges with O-Rings, Head, Dia-
phragm, Secondary O-Ring Seal, Head Screws, Washers, and an exploded
view drawing.
PM kits will save you money. When you need a part, you've got it! You
can cut downtime and production loss from days to minutes. You also
save by buying parts in PM kit form compared with buying individual
parts.
Each PM kit part is vacuum -sealed to keep it clean, even when stored for
long periods of time.
A PM kit is a troubleshooter's best friend. In the event of a breakdown,
it will put you back in business fast! Preventive maintenance will ensure
continuous high performance of your pump.
Keep on pumping! Get all the money -saving and security benefits of PM
kits immediately.
The PM kit's part number is
displayed on the pump model
label as shown.
To order the proper PM kit
model, begin with the letter
"K" followed by the 2nd, 5th,
6th, 7th, and the 8th position
of the pump model number.
