Speci cations - CP4NC, CP6NC, CP8NC

Double Seal, 4”, 6” & 8” Discharge

General:

Furnish and install a quantity of ___ Champion Pump
submersible Non-clog pump(s), Model CP_______________,
_____ HP, ______ RPM, _______ phase, 60 Hz, ________
volts, with a ____ inch horizontal discharge 125# ANSI
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, and ____ % e ciency at
______U.S. GPM at _____Ft. TDH operating point.

Pump Design:

The centrifugal non-clog pump(s) shall be capable of
handling 3 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 _____ vane, non-clog
design with pump out vanes on the back side. Single and
multi-vane 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.

Motor: Design shall be of the capacitor start and capacitor
run and overload protection for single phase units.
Capacitors shall be located in an external control box. 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 F 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: Thermal sensors shall be used to
monitor stator temperatures. The stator shall be equipped
with a thermal switch embedded in the end coil of the
stator winding. This shall be used in conjunction with and
supplemental to external motor overload protection and
wired to 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 double 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/Control Cords: Shall be equipped with_______ft. of
type SOW power and control cords. The cords 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.

Double mechanical seal: Shall be of the single spring

design operating in an oil- lled seal cavity. The inner
seal shall be constructed of carbon for the rotating face
and ceramic for the stationary face, 300 series stainless
steel hardware, and all elastomer parts to be of Buna-N.
The outer seal shall be 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.

Moisture sensor: A moisture detection system consisting
of two normally open (N/O) probes shall be installed in the
pump seal chamber. These probes will detect any moisture
present and shall be connected in series to an alarm device
or motor starter coil which will alert the operator that
moisture has been detected in the seal cavity.

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.
