The curves reflect maximum performance characteristics without exceeding full load (Nameplate) horsepower. All pumps have
a service factor of 1.2. Operation is recommended in the bounded area with operational point within the curve limit. Performance
curves are based on actual tests with clear water at 70° F. and 1280 feet site elevation.

SUBMERSIBLE SEWAGE EJECTOR MODEL:
SP50
1.01 GENERAL
Contractor shall furnish all labor, materials, equipment and incidentals required to provide (Qty.)
submersible centrifugal sewage ejector pump(s) as specified herein. The pump model covered in
this specification is the SP50. The pump furnished for this application shall be
MODEL _________ as manufactured by Hydromatic Pumps.
2.01 DESIGN CONDITIONS
Each pump shall be rated _____ H.P., _____ volts, _____ phase, _____ hertz and operate at ______
RPM.
3.01 OPERATING CONDITIONS
The pump shall deliver _____ U.S. GPM/LPS at _____ feet/meters TDH, and handle a _____ inch solid.
The curve submitted for approval shall state, in addition to head and capacity performance, solid
handling capability, amp rating, and design impeller diameter.
4.01 CONSTRUCTION
Each pump shall be of the sealed submersible type, incorporating features normally found in pumps
furnished for the residential market.
These features include:
1. The pump volute, motor, and seal housing shall be high quality gray cast iron, ASTM A-48, Class 30.
2. The pump inlet shall be open and clear, without screening to provide access for sewage and
solids.
3. All external mating parts shall be machined and Buna N, O-Ring sealed.
4. All fasteners exposed to the pumped liquid shall be 300 series stainless steel.
5. All power cords shall be water resistant UL or CSA approved, with double insulation, and sized as
a function of Amp. draw.
5.01 MOTOR AND SHAFT
The stator, rotor and bearings shall be mounted in a sealed submersible type housing. Single phase
motors shall be split phase or capacitor start with centrifugal switch. Three phase motors shall be
Polyphase. Full Load and Locked Rotor Amps as well as Start and Run winding resistance shall be
tabulated for each pump.

6.01 BEARINGS, SHAFT AND MECHANICAL SEAL
An upper radial and lower thrust bearing shall be required. These shall be heavy duty single row ball
bearings which are permanently and continuously lubricated and cooled by the dielectric oil which fills the
motor housing. The motor shaft shall be nickel plated steel and sealed from the pumped liquid with a
carbon ceramic mechanical seal.
7.01 IMPELLER
The Impeller shall be high capacity, two vane, non-clog design with pump out vanes on the back side.
These vanes wash out grit and stringy material that will damage the shaft and mechanical seal.
8.01 AUTOMATIC CONTROL
All single phase pumps should be capable of automatic operation.
9.01 PRESSURE SWITCH
The Single Phase SP50 pump is furnished with a pressure diaphragm switch that features a piggy-back
plug that allows the pump to be operated manually without removal from the sump.
10.01 PAINTING
All cast iron parts shall be painted before assembly with a water reducible alkyd air dried enamel.
The paint shall be applied in one coat with a minimum thickness of 3 to 4 mils.
11.01 TESTING
All pumps shall be individually tested to include the following:
1. The pump and power cord shall be visually inspected for imperfections, cuts or nicks.
2. The pump shall have a ground continuity check and the motor chamber shall be Hi-potted to
test for moisture content and/or insulation defects.
3. The motor and volute housing shall be pressurized and a 10 second air leak decay test run.
4. Oil is added, and the pump is run. Voltage and current are monitored visually, electronically,
and the tester listens for any noise or malfunction.
