Weil Single Seal Submersible Pumps can be used to pump wastewater, unscreened solids, water containing silt and a wide range of pollutants. Suitable applications include wastewater pits, below ground vaults, truck loading docks, parking lots, storm water pumping from underpass drainage and areas flooded from overflowing rivers, streams, etc.
Pump Features
Case
Heavy-duty, close grain, high-density cast iron. Tripod support legs on floor models.
Discharge
1-1/4 to 3 inches.
Solid Size
1/8 to 2 inches.
Impeller
Semi-open or enclosed type, statically and dynamically balanced for a quiet, efficient operation. Cast iron impellers are standard on all models except 1451 and 1452, which have a stainless steel impeller. Bronze is available as an option on most models. Stainless steel is available as an option on selected models.
Strainer
Stainless steel. Model 1451 and 1452 have a brass strainer.
Motor Features
Motor Type
NEMA 6, submersible air-filled, hermetically sealed, Class F insulation. Single-phase motors are capacitor start induction run.
Motor Horsepower
1/3 to 2 horsepower, 1750 RPM, and 3/4 to 2 horsepower, 3500 RPM.
Motor Voltage
Single-phase voltages are 60 Hz, 115 or 208-230 volt with automatic reset thermal and overload protection. Three-phase voltages are 60 Hz, 208-230 or 460 volt.
Temperature Ratings
160 degrees F – Normal Cyclical Duty
140 degrees F – Continuous Cyclical Duty
120 degrees F – Continuous Extended Duty
Motor Shell
Machined from close grain, high-density cast iron.
End Bell
Cast iron, air-filled hermetically sealed. Motor 9725 has a hermetic glass seal that separates the motor cavity from the power cord entrance. A power cord leak due to a cut and/or other damage will not permit water to enter the motor.

Buna-N O-rings for positive sealing. Viton O-rings are available as an option.
Power Cable
Cable type is neoprene jacketed. A three-conductor grounded plug is furnished on single-phase 115-volt cord sets.
Bearings
Permanently lubricated single-row, double-sealed. Oversized to handle radial and axial loads.
Mechanical Seal
Carbon against ceramic face with heat-resistant stainless steel and Buna-N components. High temperature viton components are available as an option.
Shaft
Series 300 stainless steel.
