SCOPE: Furnish and install__________ submersible effluent pump (s). Each pump shall be
capable of delivering the following performance points,__________ U.S. GPM
at_____________________ TDH ; _______________________U.S. GPM
at____________TDH; _______________U.S. GPM at ___________TDH, with a shut off head of
__________TDH (minimum). The pump motor speed shall be 3450RPM,_____ HP
(maximum),____________Phase, 60 Hertz,____________Volts. The pump (s) shall be
manufactured by a company regularly engaged in the manufacture and assembly of similar units.
The pump (s) shall be Champion Pump model_____________________________.
PUMP DESIGN: Each pump shall be capable of handling septic tank effluent with solids to 3/4
inch diameter. The pump (s) shall be capable of handling liquids with temperatures to 140
degrees F intermittent.
PUMP CONSTRUCTION: The volute, seal plates and motor housing shall be constructed of high
quality ASTM A-48 class 20-30 cast iron. The pump (s) shall be painted with a water based air
dry enamel of 2.0 mil minimum thickness. All exposed hardware shall be 300 series stainless
steel. The pump construction shall be of the high efficiency semi-open impeller design. Discharge
connection shall be a standard 2 inch NPT in the vertical position. All critical sealing areas shall
be of the compression o-ring sealing arrangement and be standard size commercially available.
The pump impeller shall be of a single or double vane design, of cast iron construction. Impellers
are dynamically balanced per ISO G6.3 specifications.
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. Motor designs incorporating shrink or
press fit assembly between the stator and motor housing shall not be acceptable. The motor shall
be constructed with the windings operating 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. Air-filled motors shall not be
acceptable. The motor windings shall be of Class F insulation. The motor shaft shall be of 416
stainless steel. The lower and upper bearing shall be of the single ball type to accept radial and
thrust loads. Bearings shall operate in an oil bath atmosphere for superior life. Permanently
lubricated or sleeve bearings are not acceptable.
Thermal sensor shall be available on three phase units to monitor stator temperatures. The stator
shall be equipped with a thermal switch embedded in the end coil of the stator winding. This can
be used in conjunction with external motor overload protection and wired to the control panel.
Single phase shall have an overload switch on the motor windings and do not require any
external protection.
The pump shall be equipped with_______ft. of type SJOW or SOW power cable and connected
to the motor via quick disconnect pin terminals. Threaded cord grip type cord entries are not
acceptable. Pin receptacles shall be crimped and molded to the power cord in a PVC plug. The
plug shall be secured with a stainless steel compression plate to prevent water from entering the
housing and to provide strain relief at the point of cable entry. A chemical bonding adhesive
seals the PVC molding to the cable jacket to prevent water from entering the jacket. A terminal
block with brass pin inserts shall connect the power cord leads with the motor leads. A Buna-N oring shall provide isolation sealing between the terminal block and the motor housing when the
cord plug is removed.

SEAL CONFIGURATION:
( ) SINGLE SEAL: The unit shall utilize a single mechanical shaft seal Type 21; which will
operate in an oil atmosphere. The materials of construction shall be carbon for the rotating face
and ceramic for the stationary face, lapped and polished to a tolerance of one light band, 300
series stainless steel hardware, and all elastomer parts to be of Buna-N. The seal shall be
commercially available and not a proprietary design of the manufacturer.
( ) DOUBLE SEAL: The unit shall utilize a tandem mechanical shaft seal arrangement and shall
operate in an oil atmoshere. The materials of construction shall be carbon for the rotating face
and ceramic for the stationary face, lapped and polished to a tolerance of one light band, 300
series stainless steel hardware, and all elastomer parts to be Buna-N. The seal shall be
commercially available and not a proprietary design of the manufacturer.
( ) An optional moisture sensor detection system consisting of two probes utilized as a
positive/negative pole shall be integrated within the oil-filled seal chamber. Units utilizing one
probe and grounding through the pump case or a float device are not acceptable.

PUMP TEST: The pump manufacturer shall perform the following inspections and tests in
accordance with SSPMA standards before shipment from the factory :
1.
A check of the motor voltage and frequency shall be made as shown on the name plate.
2.
A motor and cable insulation test for moisture content or insulation defects shall be made
per UL or CSA criteria.
3.
The pump shall be submerged and run to determine that the unit meets pre-determined
hydraulic performance points.

START-UP: The pump (s) shall be tested at start-up by a qualified representative of the
manufacturer. A start-up report as provided by the manufacturer shall be completed before final
acceptance of the pump(s).
DOCUMENTATION: The manufacturer, if requested, will supply a minimum of________sets of
standard submittal data;
Standard submittal data consist of:
a.
Pump catalog data;
b.
Pump performance curve;
c.
Break Away Fitting (BAF) data;
d.
Typical installation drawing;
e.
Control panel data
f.
Panel wiring schematic;
g.
Accessory data;
h.
Installation & Operation Manuals with Parts List.
