General: 
Furnish and install a quantity of ___Champion Pump
submersible sewage pump(s), Model PF_____________, 
_____ HP, ______ RPM, _______ phase, 60 Hz, ________ 
volts, with a  3 inch (optional 2 inch) vertical bolt-on 
discharge fl ange connection.  Each pump shall be capable 
of delivering the following performance,  _______ U.S. 
GPM at _______ Ft. Total Dynamic Head, with a shut off  
head of _______Ft. TDH minimum.

Pump Design:
The centrifugal sewage pump(s) shall be capable of 
handling 2.50 inch diameter spherical solids of raw, 
unscreened domestic sewage consisting of water, fi brous 
materials. The pump(s) shall be capable of handling 
liquids with temperatures to 104 degrees F continuous, 
and shall be capable of running dry for extended periods. 

Pump Construction:  
Castings: The volute, seal plates, impeller and motor 
housing shall be constructed of  ASTM A-48 class 30 cast 
iron. 

Coating/Hardware: Exterior surfaces shall be painted 
with a water based air dry enamel. All exposed hardware 
shall be 300 series stainless steel. 

Gaskets: All gaskets shall be of the compression square 
ring type eliminating critical slip fi ts and the possibility 
of damage during service associated with sliding o-ring 
sealing arrangements. 

Impeller: The impeller shall be of 2 vane, open type, 
non-clog design with pump out vanes on the back side. 
Impellers shall be capable of  being trimmed to meet 
specifi c performance characteristics. The impeller shall be 
dynamically balanced to ISO G6.3 specifi cations. 

Mechanical seal: A dual seal arrangement shall consist 
of a Buna-N exclusion seal and a single mechanical 
design operating in an oil-fi lled seal cavity. The seal 
shall be  constructed of  Silicon carbide faces, 300 series 
stainless steel hardware, and all elastomer parts to be of 
Buna-N. The seal shall be commercially available and not a 
manufacturers proprietary design. 

Motor: Design shall be of the split capacitor design for 
single phase units. The pump shall be designed to be non-
overloading throughout the entire pump curve. The rotor 
and stator assembly shall be of the standard frame design 
and secured to the pump seal plate by four threaded 
fasteners allowing for easy serviceability.  

The motor windings shall be of Class B insulation and 
operate in a sealed environment containing clean 
dielectric oil, making it capable of operating in a totally, 
partially or non-submerged condition for extended 
periods of time without damage due to the heat being 
generated. The used dielectric oil must be disposed of as 
non-hazardous waste. The motor shall meet the standard 
NEMA design L for single phase and NEMA design B for 
three phase.

Thermal Protection: All single phase motors shall 
have thermal protection with automatic reset. Three 
phase motors shall be equipped with a thermal switch 
embedded in the stator windings and require external 
overload protection in the control panel.

Shaft: The pump shaft shall be of a one-piece design and 
shall be of 416 stainless steel. 

Bearings:  The lower bearing shall be of the single row 
ball type to accept radial and thrust loads, and the upper 
bearing of the single ball type for radial loads. Bearings 
shall operate in an oil bath atmosphere for superior life. 

Power Cord:  All pump(s) except 1.5 and 2.0Hp 3 phase, 
shall be equipped with_______ft. of type SOW cord. The 
cord shall enter a cast iron terminal box assembly that is 
bolted to the motor housing and sealed with a Buna-N 
o-ring. The incoming lead wires shall be spliced in the 
terminal box. After splicing, the terminal box shall be 
fi lled with epoxy to seal the outer cable jacket and the 
individual strands to prevent water from entering the 
motor housing. Additional sealing and strain relief shall 
utilize a secondary pressure grommet at point of cable 
entry.

1.5 and 2.0Hp 3 phase pump(s) shall be equipped 
with_____ft. of type SOW cord. The outer cord shall have 
an epoxy fi lled heat shrink tube to prevent water from 
entering the motor housing. Terminal connectors shall 
connect the incoming lead wires with the motor lead 
wires. Additional sealing and strain relief shall utilize a 
secondary pressure grommet at point of cable entry.

Tests and inspections: Shall be performed by the pump 
manufacture. 
1.  A ground continuity check and motor chamber shall 
 

be Hi-potted to test for electrical integrity.

2.   Check that motor voltage and frequency matches name
 plate. 
3.  The pump shall be pressurized and a air leak test is 
 

performed to ensure the integrity of the motor 

 housing. 
4.  The pump is submerged and operated to determine 
 the 

unit 

meets hydraulic performance requirements.
