Submittal Sheet

3.01 CONSTRUCTION:

Each submersible pump shall be equal to the certified Series 290 SERIES 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 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 pump shall be furnished with stainless

steel handle.

4.01 ELECTRICAL POWER CORD

The submersible pump shall be supplied with 10, 25, 35, or 50 feet of multiconductor power cord. It shall be cord type SJTW, or

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 B insulated NEMA B design, rated for continuous duty. At

maximum load the winding temperature shall not exceed 130 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

An upper and lower ball bearing shall be required. The ball bearing 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 a unitized carbon / ceramic seal with stainless steel housings and spring. The motor plate / housing interface shall

be sealed with a Buna-N O-ring.

8.01 IMPELLER

The impeller shall be vortex style made of an 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 pumps can be supplied with a CSA and UL approved VMF type switch, an integrally wired wide angle tilt float switch, or piggy back

type wide angle tilt float switches. The piggy back style switches are equipped with a plug that allows the pump to be operated manually

without the removal of the pump in the event that a switch becomes inoperable. Manual pumps are operable by means of a pump

control panel.

10.01 PAINT

The exterior of the casting shall be protected with powder coat paint.
