ELV-Series Specifications
1.01 GENERAL:
The contractor shall provide labor, material, equipment, and incidentals required to provide (QTY) centrifugal pumps as
specified herein. The pump models covered in this specification are ELV Series single phase 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 for ____hp, _____ volts, single phase, 60 Hz, & 3450 RPM. The unit shall produce
_____G.P.M. at ______ feet of total dynamic head.
The submersible pump shall be capable of handling water with _____ solid handling capability. The submersible pump shall have
a shut-off head of ____ feet and a maximum flow of _____ GPM @ 5 feet of total dynamic head.
The pump shall be controlled with:
The manual pump is connected to a control which has the ability to prevent oil from being pumped from the vault. This same
control unit will activate an alarm when an oil “filmis detected or when a high water condition exits. The system will continue to
monitor and remove water from the vault even if an oil condition is detected.
3.01 CONSTRUCTION:
Each centrifugal sump pump shall be equal to the Certified ELV-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 a unitized ceramic/carbon seal with stainless steel housings
and spring or 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 a 25 feet of multiconductor power cord. It shall be cord type YELLOW
UL 16-3 SJEOOW 300V 105°C, 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.
