D3696LSG/LSGX-Series Specifications
1.01 GENERAL
The contractor shall provide labor, material, equipment, and incidentals required to provide (QTY) centrifugal grinder pumps as
specified herein. The pump models covered in this specification are LSG/LSGX-Series single/three-phase grinder pumps. The pump
furnished for this application shall be model as manufactured by Liberty Pumps.
2.01 OPERATING CONDITIONS
Each submersible pump shall be rated at 2 hp, volts, phase, 60 Hz, 3450 RPM. The unit shall produce
GPM at feet of total dynamic head.
The submersible pump shall be capable of handling residential and commercial sewage and grinding it to a fine slurry enabling it to be
pumped over long distances in pipelines as small as 1.25" in diameter. The LSG-Series single stage submersible pump shall have a shut-off
head of 110 feet and a maximum flow of 50 GPM @ 10 feet of total dynamic head. The LSGX-Series two stage submersible pump shall
have a shut-off head of 185 feet and a maximum flow of 38 GPM @ 10 feet of total dynamic head.
3.01 CONSTRUCTION
Each centrifugal grinder pump shall be equal to the . SASS certified LSG/LSGX-Series Grinder pumps as manufactured by Liberty Pumps,
Bergen NY. The castings shall be constructed of class 25 cast iron. The motor housing shall be oil filled to dissipate heat. Air filled motors
shall not be considered equal since they do not properly dissipate heat from the motor. All mating parts shall be machined and sealed
with a Buna-N 0-ring. All fasteners exposed to the liquid shall be stainless steel. The motor shall be protected on the top side with sealed
cord entry plate with molded pins to conduct electricity eliminating the ability of water to enter internally through the cord. The motor
shall be protected on the lower side with a dual seal arrangement. The first seal is a double lip seal molded in fluoroelastomer or Buna-N.
The second/main seal shall be a unitized hard face silicon carbide seal with stainless steel housings and spring.
The upper and lower bearing shall be capable of handling all radial thrust loads. The lower bearing shall have the additional ability to
handle the downward axial thrust produced by the impeller and cutters by design of angular contact roller races. The pump housing shall
be of the concentric design thereby equalizing the pressure forces inside the housing which will extend the service life of the seals and
bearings. Additionally there shall be no cutwater in the housing volute in order to discourage the entrapment of flowing debris. The pump
shall be furnished with a stainless steel handle having a nitrile grip.
4.01 ELECTRICAL POWER CORD
The submersible pumps shall be supplied with 25 feet of multi -conductor power cord QS feet for external capacitor models). It shall be
cord type SJOOW (1-phase), SEOOW (3-phase), or SOOW (external capacitor models), capable of continued exposure to the pumped
liquid. The power cord shall be sized for the rated full load amps of the pump in accordance with the National Electric Code. The power
cable shall not enter the motor housing directly but will conduct electricity to the motor by means of a water tight compression fitting
cord plate assembly, with molded pins to conduct electricity. This will eliminate the ability of water to enter internally through the cord, by
means of a damaged or wicking cord.
5.01 MOTORS
All motors shall be oil filled and class B insulated NEMA B design, rated for continuous duty. Since air filled motors are not capable of
dissipating heat as effectively, they shall not be considered equal. At maximum load, the winding temperature shall not exceed 105°C for
model LSG202 and 135°C for LSG202-C and LSGX models (unsubmerged). Single-phase motors shall be capacitor start/capacitor run and
have an integral thermal overload switch in the windings for protecting the motor.

6.01 BEARINGS AND SHAFT
An upper radial and lower thrust bearing shall be required. The upper bearing shall be a single ball / race type bearing. The lower bearing
shall be an angular contact heavy duty ball/race type bearing, designed to handle axial grinder pump thrust loads. Both bearings shall be
permanently lubricated by the oil, which fills the motor housing. The bearing system shall be designed to enable proper cutter alignment
from shut off head to maximum load at 10 feet of TDH. The motor shaft shall be made of 300 series stainless steel and have a minimum
diameter of 0.670".
7.01 SEALS
The pumps shall have a dual seal arrangement consisting of a lower and upper seal to protect the motor from the pumping liquid. The
lower seal shall be fluoroelastomer OR Buna-N molded double lip seal, designed to exclude foreign material away from the main upper
seal. The upper seal shall be a unitized silicon carbide hard face seal with stainless steel housings and spring equal to Crane Type T-6a. The
motor plate/housing interface shall be sealed with a Buna-N O-ring.
8.01 IMPELLER
The impeller shall be an investment cast stainless steel impeller, with pump out vanes on the back shroud to keep debris away from the
seal area. It shall be keyed and bolted to the motor shaft.
9.01 CUTTER MECHANISM
The cutter and plate shall consist of 440 stainless steel with a Rockwell C hardness of 55-60. The stationary cutter plate shall have specially
designed orifices through it, which enable the slurry to flow through the pump housing at an equalized pressure and velocity. The
stationary cutter shall consist of V shapes to maximize cutting action and arc shape exclusion slots to outwardly eject debris from under
the rotary cutter. The rotary cutter shall have (4) blades and be designed with a recessed area behind the cutting edge to prevent the
accumulation and binding of any material between rotary cutter and the stationary cutter. The cutting system must incorporate close
tolerances for optimum performance. Ring or radial cutters, or those that grind on the outside circumference, shall not be considered
equal.
10.01 CONTROLS
The pumps shall be controlled with a NEMA 4X outdoor duplex control panel with three float switches and a high water alarm or with
optional IP Series NEMA 4X outdoor duplex control panel with transducer, adjustable set -points, data logging, and a high water alarm.
11.01 PAINT
The exterior of the casting shall be protected with powder coat paint.
12.01 SUPPORT
The pumps shall have cast iron support legs, enabling it to be a freestanding unit. The legs will be high enough to allow solids and long
stringy debris to enter the cutter assembly.
13.01 SERVICEABILITY
Components required for the repair of the pump shall be shipped within a period of 24 hours.
14.01 FACTORY ASSEMBLED TANK SYSTEMS WITH GUIDE RAIL AND QUICK DISCONNECT DISCHARGE
Factory mounted guide rail system with pump suspended by means of bolt -on quick disconnect which is sealed by means of nitrile
grommets. The discharge piping shall be schedule 80 PVC and furnished with a check valve and PVC shut-off ball valve. The tank shall be
wound fiberglass, and an inlet hub shall be provided with the system.

15.01 TESTING
The pumps shall have a ground continuity check and the motor chamber shall be hi -potted to test for electrical integrity, moisture content
and insulation defects. The motor and volute housing shall be pressurized, and an air leak decay test is performed to ensure integrity of
the motor housing. The pump shall be run, voltage current monitored, and checked for noise or other malfunction.
16.01 QUALITY CONTROL
The pumps shall be manufactured in an ISO 9001 certified facility.
17.01 WARRANTY
Standard limited warranty shall be 3 years.
