405-Series Specifications
1.01 GENERAL:
The contractor shall provide labor, material, equipment, and incidentals required to provide (QTY) commercial drain pumps as
specified herein. The pump models covered in this specification are Series 405 single phase pumps. The pump furnished for this
application shall be model ______________as manufactured by Liberty pumps, and have a maximum fluid temperature rating of 180
degrees F.
2.01 OPERATING CONDITIONS:
Each drain pump shall be rated at 1/2 hp_____ volts, single phase, 60 Hz. 3450 RPM. The unit shall produce ______G.P.M. at ______
feet of total dynamic head.
The drain pump shall be capable of handling effluent with 3/8” solid handling capability. The drain pump shall have a shut-off head of 34
feet and a maximum flow of 48 GPM @ 5 feet of total dynamic head.
The pump shall be controlled with a piggy back style on/off float switch.
3.01 CONSTRUCTION:
Each drain pump shall be equal to the certified Series 405 SERIES pumps as manufactured by Liberty Pumps, Bergen NY. The
motor housing shall be constructed of a deep finned powder coated aluminum. 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 o-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 an engineered double lip seal with stainless steel springs. The tank shall be made of
polypropylene.
4.01 ELECTRICAL POWER CORD
The drain pump shall be supplied with 10 feet of multiconductor power cord. It shall be cord type SJTOOW, 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
Single phase motors shall be oil filled, permanent split capacitor, class F insulated, NEMA B design, rated for continuous duty. At
maximum load the winding temperature shall not exceed 155 degrees C unsubmerged. Since air filled motors are not capable of
dissipating heat they shall not be considered equal. The pump motor shall have an integral thermal overload switch in the windings for
protecting the motor. The capacitor circuit shall be mounted internally in the pump.

6.01 BEARINGS AND SHAFT
Upper and lower ball bearings shall be required. The bearings shall be a single ball / race type bearing. Both bearings shall be
permanently lubricated by the oil, which fills the motor housing. The motor shaft shall be made of 300 or 400 series stainless steel and
have a minimum diameter of .311".
7.01 SEALS
The pump shall have an engineered double lip seal with stainless steel springs. The motor plate / housing interface shall be sealed with a
Buna-N o-ring.
8.01 IMPELLER
The impeller shall be molded engineered polymer, with pump out vanes on the back shroud to keep debris away from the seal area. It
shall be threaded to the motor shaft.
9.01 CONTROLS
All units are supplied with CSA and UL approved automatic wide angle tilt float switches. The switches shall be equipped with piggy back
style plug that allows the pump to be operated manually without the removal of the pump in the event that a switch becomes inoperable.
The switches shall be mounted under a separately sealed access cover and tethered to a removable stainless steel rod for easy removal
and serviceability.
10.01 PAINT
The exterior of the casting shall be protected with powder coat paint.
11.01 SUPPORT
The polyolefin tank shall be a free standing unit.
12.01 SERVICEABILTY
Components required for the repair of the pump shall be shipped within a period of 24 hours.
13.01 TESTING
The pump 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 the tester checks for noise or other malfunction.
14.01 QUALITY CONTROL
The pump shall be manufactured in an ISO 9001 certified Facility.
15.01 WARRANTY
Standard limited warranty shall be 3 years.
