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  ange connection. Each pump shall be capable
of delivering the following performance, _______ U.S.
GPM at _______ Ft. Total Dynamic Head, with a shut o
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,  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  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
speci c performance characteristics. The impeller shall be
dynamically balanced to ISO G6.3 speci cations.
Mechanical seal: A dual seal arrangement shall consist
of a Buna-N exclusion seal and a single mechanical
design operating in an oil- 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
 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  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.
