250 GPD per dwelling unit which was previously approved in accordance with North Carolina
Administrative Code,to 190 GPD per dwelling unit for single family residential areas and 135 GPD per
dwelling unit for multi-family residentialareas. In support of your request,documentation was provided
from the existing Irwin,Sugar,and McAlpine Creek wastewater treatment plant service areas.
The documentation provided in support of the flow reduction request was compiled by Camp
Dresser&McKee starting in late 1990 and is currently ongoing. Data submitted to the Division was not in
strict accordance with 15A NCAC .0219(1)(3), however, in view of the submitted documentation,
adequate justification was provided in support of the wastewater flow reduction request. The work
completed by Camp Dresser&McKee consisted of tracking base wastewater flows,groundwater
infiltration,and rainfall-dependent infiltration/inflow for the Irwin,Sugar, and McAlpine Creek
wastewater treatment plant service areas. Data was collected from 106 flow monitors(both permanent and
temporary)and 14 rain gauges during November and December 1991 located along major sewer trunklines
within the study area. Existing dry-weather flows were developed for each of the three(3)wastewater
treatment plant service areas which included groundwater infiltration. The service area dry-weather flow
estimates were further broken-down into thirteen(13)drainage basins. These revised dry-weather flow
estimates were compared to land-use based flow estimates developed using existing land data for 446
Origination and Destination(O&D)planning zones as provided by the City of Charlotte's Department of
Transportation. From this comparison the revised wastewater flows were developed. Although these
numbers were developed for Irwin, Sugar,and McAlpine Creek service areas, the results would also be
applicable to both the Mallard Creek and McDowell Creek wastewater treatment plant service areas.
In view of the information submitted,the Division of Environmental Management will allow the
use of 190 GPD per dwelling unit for single family residential areas and 135 GPD per dwelling unit for
multi-family residential areas on all applicable non-discharge permit applications for future wastewater
collection extensions which will be made tributary to all five(5)Charlotte-Mecklenburg Utility Department
wastewater treatment facilities. This consideration applies to any applicable future projects submitted to
this Division as well as any projects which are presently under review. Wastewater flows presently
tributary to the wastewater treatment facilities can be adjusted upon negotiations between the Charlotte-
Meckknburg Utility Department and the Division's Mooresville Regional Office.

Charlcue-Mecklenburg Utility Department
February 13, 1995
The Division does have concerns regarding the proposed sewage flow rates with respect to
infiltration and inflow. Although the 190 GPD per dwelling unit for single family residential areas and
135 GPD per dwelling unit for multi-family residential areas are justifiable flow rates,the Charlotte-
Mecklenburg Utility Department has in essence reduced the safety factor typically associated with
infiltration and inflow. The flow rate established by the Division does allow for some infiltration and
inflow. The Division is of the opinion that proper wastewater collection system management is more
effectively and efficiently accomplished by the entity that is accountable for ensuring overall compliance
with all aspects of wastewater collection,treatment, and disposal requirements. In this view, we look
forward to continued progress by the Charlotte-Mecklenburg Utility Department to fully assume the
wastewater collection permitting program.

Pump Station(Name or Number):
Given that:
a. The proportion and amount of Obligated,Not Yet Tributary Daily Flow(C)accounts for
19.3 %and 1.239 MGD of the Available Capacity(E) in Pump Station
Long Creek and Paw Creek ; and that
b. The rate of activation of this obligated,not yet tributary capacity is currently approximately
1.239 MGD per year; and that
c. A funded Capital Project that will provide the required planned capacity,namely
Stowe Regional Water Resource Recovery Facility is in design or under construction with
planned completion in 2026 ; and/or Paw Creek FM Replacement-2022
d. The following applies: Paw Creek Pump Station Improvements-2023
Charlotte Waters Capital Improvement Plan has allocated funds for improvements to the Paw Creek Pump Station Improvements and a new Stowe
Regional Water Resource Recovery Facility("Stowe Regional").The design plan is for Stowe Regional to use the Long Creek Pump Station(LCPS)
to house the second stage pumps of its influent pump station. In the short term,LCPS will also continue to house pumps which export flow to Paw Creek PS
("Paw Creek export pumps"). Currently LCPS has 8 MGD of export capacity,which will be increased to 12 MGD(firm)by the 2nd quarter of 2024.
Stowe Regional is under design and expected to come online in early 2026. Before Stowe Regional is brought online,a new headworks and Influent Pumping Station
building will be constructed adjacent to the LCPS,which will house the first stage influent pumps for Stowe and be the Paw Creek export pumps.
Currently,Long Creek and Paw Creek operate as a combined system with the Long Creek pump station able to transfer flows to flow equalization
tanks during peak flow events and then meter out flow to Paw Creek as conditions allow.
Paw Creek Pump Station was awarded a permit on 8/27/2020 to increase firm pumping capacity to 20 MGD.Construction on this project has begun,
and this project is anticipated to be substantially complete March 2023.The Force Main replacement project has been completed.
Therefore:
Given reasonably expected conditions and planning information, there is sufficient justification to allow
this flow to be permitted, without a significant likelihood of over-allocating capacity in the system
infrastructure.
I understand that this does not relieve the collection system owner from complying with G.S. 143-
215.67(a) which prohibits the introduction of any waste in excess of the capacity of the waste disposal
system.

An adequate number of sealing-type cord grips shall be supplied for incoming pump and level control cords.The
cord grips shall be made of non-corrosive material, such as PVC or nylon, and shall make an effective seal around
the wire jacket.The cord grips shall also seal to the junction box with an "0" ring or gasket.
The junction box shall have a PVC solvent weld socket type conduit hub of adequate size to accommodate the
number of wires required for pump and level control operation.The incoming wires shall be sealed by an
external EY type seal-off(supplied by others)so that condensation from the conduit or groundwater will not
enter the enclosure.The interior of the enclosure shall be of adequate size to accommodate the wires and
connections for pump and level control operation.
The wires running between the control panel and the junction box shall be color-coded and fastened to the
pump and level controls by means of adequately sized and insulated twist lock or crimp connectors.
The junction box shall be designed to NEMA 6 standards for occasional submergence.
LEVEL CONTROLS: Pump on, off and alarm levels shall be controlled by three (3) mercury tube float switches.
Switches shall consist of a mercury tube switch sealed in a corrosion-resistance polypropylene housing with a
minimum of 18 gauge, 2-wire,SJOW/A jacketed cable.The cable shall be of sufficient length to reach the
junction box with no splices.The level controls shall be suspended from a stainless-steel bracket so that
adjustment or replacement may be done without the use of any tools. Level controls shall be UL/CSA listed.

INSTALLATION
1. REMOVE PACKING MATERIAL:
The User Instructions must be given to the homeowner. Hardware supplied with the unit, if required,will be
used at installation.
2. TANK INSTALLATION:
The tank is supplied with a standard 4" PVC DWV(4.5" inside Dia.)grommet for connecting the incoming
sewer drain. Other inlet types and sizes are optional. Please confirm that you have the correct inlet before
continuing. Do not drop,roll,or lay tank on its side.
Excavate a hole to a depth,so that the removable cover extends above the finished grade line,the grade
should slope away from the unit.The diameter of the hole must be large enough to allow a concrete anchor. Place
the unit on a 6" bed of gravel, naturally rounded aggregate, clean and free-flowing,with particle size not less than
1/8" or more than 3/" in diameter.The concrete anchor is required to keep the unit from floating due to high
ground water levels.The amount of concrete required varies for each respective unit. (See Station Detail Sheet for
the correct ballast weight of your unit).
The unit should be leveled,and the wetwell filled with water,to the bottom of the inlet,to help prevent
the unit from shifting while the concrete is being poured.The concrete must be manually vibrated to ensure there
are no voids. If it is necessary to pour the concrete to a level higher than the inlet piping, an 8"sleeve is required
over the inlet prior to the concrete being poured.
An exfiltration leakage test shall be performed on the wetwell by filling and marking the water level.The
leakage test shall last at least two(2) hours and the allowable leakage rate shall be 0.83 gallons per hour
(20 gpd/1000 gallons).
3. INLET PIPE INSTALLATION:
Mark the inlet pipe 3 36"from the end to be inserted. Inlet pipe should be chamfered and lubricated with a
soap solution. Lubricate the grommet with the soap solution, also. Insert the inlet pipe up to the 3'A" mark.
Inspect to make sure the grommet has stayed in place.
4. DISCHARGE
The use of 1%" PVC(SCH-40) pressure pipe of polyethylene water service tubing(SDR 9,Type PE3206 or
PE3306)with a minimum pressure rating of 160 psi is recommended. If polyethylene pipe is chosen, use
compression type fittings to provide a smooth inner passage (insert fittings are susceptible to clogging).A
redundant check valve shall be installed between the pump discharge and the street main on all installations.The
valve shall be installed as close to the public Right-of-Way as possible.
5. BACKFILL REQUIREMENTS:
Proper backfilling is essential to the long term reliability of any underground structure. Several methods of
backfill are available and each will yield favorable results when done properly.
Clean, compatible, native soil free of rocks, roots, or organic material may be used if compacted in lifts not to
exceed one foot. It must be compacted to a final Proctor Density between 85%and 90% Heavy, non-compatible
clays are not acceptable backfill for this or any underground structure such as inlet or discharge lines.
Proper backfilling can also be accomplished by using Class 1 or Class 2 backfill material as defined by ASTM
2321. Crushed stone and gravel backfill materials offer an advantage since they will typically reach a compaction
level of 90-95%standard density and minimal compaction.
6. VENTING:
The unit must be properly vented to assure correct operation.The unit may be vented through the 2" port
supplied at the top of the wetwell.
Yarbrough-Williams&Houle,Inc.-P.O.Box 1198-Pineville,NC 28134-[phone] 8

7. ELECTRICAL CONNECTION:
Before proceeding,verify that the service voltage is the same as the motor voltage shown on the name plate.
An audible and visual alarm device is to be installed in a conspicuous location where it can be readily seen by the
homeowner.An alarm device is required on every installation.The shall be no exceptions.

Specifications
MYERS V2 Series
OPERATING CONDITIONS—Each pump shall be rated hp, volts, phase,
hertz, and rpm. The unit shall produce U.S. GPM at feet TDH.
CONSTRUCTION —Each pump shall be of the sealed submersible grinder type, model V2 as manufactured by
Myers. The pump volute, motor and seal housing shall be high quality gray cast iron, ASTM A-48, Class 30. All
external mating parts shall be machined and Nitrile 0-ring sealed on a beveled edge. Gaskets shall not be
acceptable. All fasteners exposed to the pumped liquid shall be 300 series stainless steel.
ELECTRICAL POWER CORD—Electric power cord shall be SOOW water resistant 600V, UL and/or
CSA approved. The single cord shall incorporate both power and sensor leads and shall be a minimum of five
12 gauge conductors. The pump shall be protected with compression fitting and epoxy potted area at the power
cord entry to the pump. A separation between the junction box area of the pump and the motor, by a stator lead
sealing gland or terminal board, shall not be acceptable. The power cable entry into the cord cap assembly shall
first be made with a compression fitting. Each individual lead shall be stripped down to bare wire, at staggered
intervals, and each strand shall be individually separated. This area of the cord cap shall then be filled with an
epoxy compound potting which will prevent water contamination to gain entry even in the event of wicking or
capillary attraction. The power cord leads shall be connected to the motor leads with extra heavy connectors
having copper inserts with a crimped wire-to-wire connection rather than a terminal board that allows for possible
leaks. The cord cap assembly shall be sealed with a Nitrile 0-ring on a beveled edge to assure proper sealing.
OPTIONAL ELECTRIC POWER CORD—Power cord shall be SOOW water resistant 600V, UL and/or CSA
approved. The single cord shall incorporate both power and sensor leads and shall be a minimum of five 12
gauge conductors. The pump shall be double protected with a compression fitting and an epoxy potted area at the
power cord entry to the pump. A separation between the junction box areas of the pump and the motor, by a
stator lead sealing gland or terminal board, shall not be acceptable. The power cable entry into the cord cap
assembly shall first be made with a compression fitting. Each individual lead shall be stripped down to bare wire
installed in a socket and enclosed in an over molding. Mating pins shall be provided and attached to the individual
Teflon lead wires and enclosed in another over molding which will be affixed to the cord cap. This area of the cord
cap shall then be filled with an epoxy potting compound. This assembly will prevent water contamination from
gaining entry even in the event of wicking or capillary action. Strain relief shall be integral to the power cable and
must be clamped over the molding and vulcanized to the outer jacket of the cable. The cord cap assembly shall
be sealed with a Nitrile 0-ring on a beveled edge to assure proper sealing.
MOTOR—The stator, rotor and bearings shall be mounted in a sealed submersible type housing. The stator
windings shall have Class F insulation (155°C or 311°F)and a dielectric oil-filled motor, NEMA B design (three-
phase), NEMA L design (single-phase). Because air-filled motors do not dissipate heat as efficiently as oil-filled
motors, they shall not be acceptable. The pump and motor shall be specifically designed so that they may be
operated partially dry or completely submerged in the liquid being pumped. The pump shall not require cooling
water jackets. Supplemental cooling shall not be acceptable.
Yarbrough-Williams&Houle,Inc.-P.O.Box 1198-Pineville,NC 28134-[phone] 14

BEARINGS AND SHAFT—An upper single row ball radial bearing and a lower double row angular contact
bearing shall be provided. Bearings shall be permanently lubricated by the dielectric oil that fills the motor
housing. The shaft shall be machined from solid 400 series stainless steel and be designed with large diameters
and minimum overhang to reduce shaft deflection and prolong bearing and seal life.
SEALS AND SENSORS—The rotor and stator in the motor housing shall be separated and protected from the
pumped liquid by an oil-filled seal housing incorporating two type 21 carbon ceramic mechanical seals mounted in
tandem. The seal housing shall be equipped with a moisture sensing probe installed between the seals, and the
sensing of moisture in the seal chamber shall be automatic, continuous and not require the pump be stopped or
removed from the wet well.
IMPELLER—The impeller shall be constructed of ASTM A536-80 ductile iron and be designed for rough duty
service. It shall be a ten-vane, semi-open design with four wash out vanes on the rear shroud. The impeller shall
be a non-overloading design and be factory or field trimable to meet specific performance conditions.
GRINDER MECHANISM—The stationary cutter shall be circular in design and contain evenly spaced cutting
slots that extend outwards from the inlet of the pump. The slots are tapered inward toward the inlet to help direct
slurry through the cutting slots into the pump. The slots are to be angled, or undercut,to help maintain a sharp
axial cutting edge, even as the axial face wears during use. The stationary cutter shall be pressed into the suction
opening of the volute and held in place by four 300 series stainless steel screws. The stationary cutter shall be
provided with tapped back-off holes so that screws can be used to remove the cutter from the volute. The rotating
cutter shall contain three axial cutting arms extending from the hub, perpendicular to the pump shaft, that are
shaped to aid in the rejection of suspended debris that has not been sufficiently reduced in size by the axial
cutting action. The curved, leading edge of the cutting arms shall create a scissor action with the cutting slots of
the stationary cutter plate to minimize the required torque. This will allow the cutter to macerate tough objects and
prolong cutter life. Serrations on the hub of the cutter add additional cuts that prevent debris from becoming
entangled within the rotating cutter. The rotating cutter shall thread onto the end of the pump shaft and be
secured by a 300 series stainless steel washer in conjunction with a 300 series stainless steel flat head cap screw
threaded into the end of the shaft. Both stationary and rotating cutters shall be made of 440C stainless steel,
hardened to Rockwell 57-60C and ground close to tolerance. The grinder shall be capable of grinding normal
domestic sewage into a fine slurry.
PAINT—The pump shall be painted with waterborne hybrid acrylic/alkyd paint. This custom engineered, quick dry
paint shall provide superior levels of corrosion and chemical protection.

pressure sewer mains from water mains in accordance with the Specifications for Construction. All
PVC pressure sewer main will be installed with locator wire or tracer strip.
6. The discharge point of the pressure sewer main to the conventional gravity sewer has been located
at an elevation higher than the pressure sewer system and lots served.
7. Flotation is addressed by the manufacturer through the use of a concrete anchor as outlined in the
installation instructions and detailed plans.
8. The storage capacity of the wet well specified is 190 gallons. The average flow for a single-family
unit is 190 GPD. Storage for a 24 hour period from a single-family unit is 190 gals. A 36-inch
diameter wet well will provide 190 gallons with 12"freeboard at 72 inches. The pump-on elevation
will be set at 16 inches. The total depth of basin is 72 inches.
9. The Wastewater Collection System shall consist of all low pressure sewer mains,plug valves,
cleanouts,air release valves,etc.located within the Public Right-of-Way or dedicated Utility
Easements. The Wastewater Collection System shall also include the 1.5-inch service line and the
service box located within the Public Right-of-Way. The Wastewater Collection System shall be
owned,operated,and maintained by Charlotte Water.
10. The Disposal System shall consist of the 1.25-inch discharge piping from the service box to the
simplex pump station,and the simplex pump station with all related appurtenances. The Disposal
System shall be owned,operated and maintained by the developer until the permit is modified to be
maintained by the Homeowners Association.
11. The Developer/HOA shall maintain spare pumps on hand in a quantity equal to 10 percent of the

diameter basins shall be constructed of non-skid,tread-plate steel with a minimum thickness of%"and shall be
coated with baked-on epoxy paint.All covers shall be grass green in color. Covers shall be bolted to the basin
with stainless steel cap screws.Zinc plated nuts shall be embedded in the upper flange of the fiberglass basin for
corrosion resistance and to prevent turning.
RAIL ASSEMBLY: The lift-out rail system assembly shall permit easy removal and installation of the pump
and lower check valve without the necessity of personnel entering the wetwell. Bronze guide brackets with
guide yokes of sufficient bearing strength to prevent binding shall bolt to the pump.The yokes shall mate over
guide rails of a minimum of 1-inch pipe running between an upper rail support and the discharge case.A lower
discharge nozzle,downstream from the check valve, shall be guided into a chamfered cavity in the discharge
case.A shoulder on the nozzle shall bottom on the discharge case to insure alignment for a leak tight seal. Dual
"0" rings shall affect a hydraulic seal around the nozzle when it is in its operating position. A brace, easily
removable from the top of the wetwell,shall be provided to lock the parts together and to prevent line surges
from breaking the seal and allowing leakage.The discharge case shall have a discharge opening for installation of
discharge piping.
CHECK VALVE: A heavy duty spring loaded all rubber flapper type check valve with cast iron body shall be an
integral part of the discharge seal assembly and lift out with the pump assembly.The valve design shall be such
to allow for operation when negative heads, up to 5 feet, are encountered.The valve shall be designed to
operate at all pressures in the sewer system created by the grinder pumps.
A flat set stainless steel spring, internally molded into the Buna N rubber flapper,shall be furnished in order to

INSTALLATION
1. REMOVE PACKING MATERIAL:
The User Instructions must be given to the homeowner. Hardware supplied with the unit, if required,will be
used at installation.
2. TANK INSTALLATION:
The tank is supplied with a standard 4" PVC DWV(4.5" inside Dia.)grommet for connecting the incoming
sewer drain. Other inlet types and sizes are optional. Please confirm that you have the correct inlet before
continuing. Do not drop, roll,or lay tank on its side.
Excavate a hole to a depth,so that the removable cover extends above the finished grade line,the grade
should slope away from the unit.The diameter of the hole must be large enough to allow a concrete anchor. Place
the unit on a 6" bed of gravel, naturally rounded aggregate,clean and free-flowing,with particle size not less than
1/8"or more than%" in diameter.The concrete anchor is required to keep the unit from floating due to high
ground water levels.The amount of concrete required varies for each respective unit. (See Station Detail Sheet for
the correct ballast weight of your unit).
The unit should be leveled, and the wetwell filled with water,to the bottom of the inlet,to help prevent
the unit from shifting while the concrete is being poured.The concrete must be manually vibrated to ensure there
are no voids. If it is necessary to pour the concrete to a level higher than the inlet piping, an 8"sleeve is required
over the inlet prior to the concrete being poured.
An exfiltration leakage test shall be performed on the wetwell by filling and marking the water level.The
leakage test shall last at least two(2) hours and the allowable leakage rate shall be 0.83 gallons per hour
(20 gpd/1000 gallons).
3. INLET PIPE INSTALLATION:
Mark the inlet pipe 3 %"from the end to be inserted. Inlet pipe should be chamfered and lubricated with a
soap solution. Lubricate the grommet with the soap solution, also. Insert the inlet pipe up to the 3 A" mark.
Inspect to make sure the grommet has stayed in place.
4. DISCHARGE
The use of 1%" PVC(SCH-40) pressure pipe of polyethylene water service tubing(SDR 9,Type PE3206 or
PE3306)with a minimum pressure rating of 160 psi is recommended. If polyethylene pipe is chosen, use
compression type fittings to provide a smooth inner passage (insert fittings are susceptible to clogging).A
redundant check valve shall be installed between the pump discharge and the street main on all installations.The
valve shall be installed as close to the public Right-of-Way as possible.
5. BACKFILL REQUIREMENTS:
Proper backfilling is essential to the long term reliability of any underground structure.Several methods of
backfill are available and each will yield favorable results when done properly.
Clean, compatible, native soil free of rocks, roots, or organic material may be used if compacted in lifts not to
exceed one foot. It must be compacted to a final Proctor Density between 85%and 90% Heavy, non-compatible
clays are not acceptable backfill for this or any underground structure such as inlet or discharge lines.
Proper backfilling can also be accomplished by using Class 1 or Class 2 backfill material as defined by ASTM
2321. Crushed stone and gravel backfill materials offer an advantage since they will typically reach a compaction
level of 90-95%standard density and minimal compaction.
6. VENTING:
The unit must be properly vented to assure correct operation.The unit may be vented through the 2" port
supplied at the top of the wetwell.
Yarbrough-Williams&Houle,Inc.-P.O.Box 1198-Pineville,NC 28134-[phone] 8

7. ELECTRICAL CONNECTION:
Before proceeding,verify that the service voltage is the same as the motor voltage shown on the name plate.
An audible and visual alarm device is to be installed in a conspicuous location where it can be readily seen by the
homeowner. An alarm device is required on every installation.The shall be no exceptions.

Specifications
MYERS V2 Series
OPERATING CONDITIONS—Each pump shall be rated hp, volts, phase,
hertz, and rpm. The unit shall produce U.S. GPM at feet TDH.
CONSTRUCTION—Each pump shall be of the sealed submersible grinder type, model V2 as manufactured by
Myers. The pump volute, motor and seal housing shall be high quality gray cast iron, ASTM A-48, Class 30. All
external mating parts shall be machined and Nitrile 0-ring sealed on a beveled edge. Gaskets shall not be
acceptable. All fasteners exposed to the pumped liquid shall be 300 series stainless steel.
ELECTRICAL POWER CORD— Electric power cord shall be SOOW water resistant 600V, UL and/or
CSA approved. The single cord shall incorporate both power and sensor leads and shall be a minimum of five
12 gauge conductors. The pump shall be protected with compression fitting and epoxy potted area at the power
cord entry to the pump. A separation between the junction box area of the pump and the motor, by a stator lead
sealing gland or terminal board, shall not be acceptable. The power cable entry into the cord cap assembly shall
first be made with a compression fitting. Each individual lead shall be stripped down to bare wire, at staggered
intervals, and each strand shall be individually separated. This area of the cord cap shall then be filled with an
epoxy compound potting which will prevent water contamination to gain entry even in the event of wicking or
capillary attraction. The power cord leads shall be connected to the motor leads with extra heavy connectors
having copper inserts with a crimped wire-to-wire connection rather than a terminal board that allows for possible
leaks. The cord cap assembly shall be sealed with a Nitrile 0-ring on a beveled edge to assure proper sealing.
OPTIONAL ELECTRIC POWER CORD— Power cord shall be SOOW water resistant 600V, UL and/or CSA
approved. The single cord shall incorporate both power and sensor leads and shall be a minimum of five 12
gauge conductors. The pump shall be double protected with a compression fitting and an epoxy potted area at the
power cord entry to the pump. A separation between the junction box areas of the pump and the motor, by a
stator lead sealing gland or terminal board, shall not be acceptable. The power cable entry into the cord cap
assembly shall first be made with a compression fitting. Each individual lead shall be stripped down to bare wire
installed in a socket and enclosed in an over molding. Mating pins shall be provided and attached to the individual
Teflon lead wires and enclosed in another over molding which will be affixed to the cord cap. This area of the cord
cap shall then be filled with an epoxy potting compound. This assembly will prevent water contamination from
gaining entry even in the event of wicking or capillary action. Strain relief shall be integral to the power cable and
must be clamped over the molding and vulcanized to the outer jacket of the cable. The cord cap assembly shall
be sealed with a Nitrile 0-ring on a beveled edge to assure proper sealing.
MOTOR—The stator, rotor and bearings shall be mounted in a sealed submersible type housing. The stator
windings shall have Class F insulation (155°C or 311°F)and a dielectric oil-filled motor, NEMA B design (three-
phase), NEMA L design (single-phase). Because air-filled motors do not dissipate heat as efficiently as oil-filled
motors, they shall not be acceptable. The pump and motor shall be specifically designed so that they may be
operated partially dry or completely submerged in the liquid being pumped. The pump shall not require cooling
water jackets. Supplemental cooling shall not be acceptable.
Yarbrough-Williams&Houle,Inc.-P.O.Box 1198-Pineville,NC 28134 -[phone] 14

BEARINGS AND SHAFT—An upper single row ball radial bearing and a lower double row angular contact
bearing shall be provided. Bearings shall be permanently lubricated by the dielectric oil that fills the motor
housing. The shaft shall be machined from solid 400 series stainless steel and be designed with large diameters
and minimum overhang to reduce shaft deflection and prolong bearing and seal life.
SEALS AND SENSORS—The rotor and stator in the motor housing shall be separated and protected from the
pumped liquid by an oil-filled seal housing incorporating two type 21 carbon ceramic mechanical seals mounted in
tandem. The seal housing shall be equipped with a moisture sensing probe installed between the seals, and the
sensing of moisture in the seal chamber shall be automatic, continuous and not require the pump be stopped or
removed from the wet well.
IMPELLER—The impeller shall be constructed of ASTM A536-80 ductile iron and be designed for rough duty
service. It shall be a ten-vane, semi-open design with four wash out vanes on the rear shroud. The impeller shall
be a non-overloading design and be factory or field trimable to meet specific performance conditions.
GRINDER MECHANISM —The stationary cutter shall be circular in design and contain evenly spaced cutting
slots that extend outwards from the inlet of the pump. The slots are tapered inward toward the inlet to help direct
slurry through the cutting slots into the pump. The slots are to be angled, or undercut,to help maintain a sharp
axial cutting edge, even as the axial face wears during use. The stationary cutter shall be pressed into the suction
opening of the volute and held in place by four 300 series stainless steel screws. The stationary cutter shall be
provided with tapped back-off holes so that screws can be used to remove the cutter from the volute. The rotating
cutter shall contain three axial cutting arms extending from the hub, perpendicular to the pump shaft, that are
shaped to aid in the rejection of suspended debris that has not been sufficiently reduced in size by the axial
cutting action. The curved, leading edge of the cutting arms shall create a scissor action with the cutting slots of
the stationary cutter plate to minimize the required torque. This will allow the cutter to macerate tough objects and
prolong cutter life. Serrations on the hub of the cutter add additional cuts that prevent debris from becoming
entangled within the rotating cutter. The rotating cutter shall thread onto the end of the pump shaft and be
secured by a 300 series stainless steel washer in conjunction with a 300 series stainless steel flat head cap screw
threaded into the end of the shaft. Both stationary and rotating cutters shall be made of 440C stainless steel,
hardened to Rockwell 57-60C and ground close to tolerance. The grinder shall be capable of grinding normal
domestic sewage into a fine slurry.
PAINT—The pump shall be painted with waterborne hybrid acrylic/alkyd paint. This custom engineered, quick dry
paint shall provide superior levels of corrosion and chemical protection.
