Weil Double 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.
Heavy-duty, close grain, high-density cast iron. Tripod support legs on floor models.
Statically and dynamically balanced. Cast iron impellers are standard on all models. Bronze is available as an option on most models.
Cast iron or stainless steel.
Stainless steel except for discharge flange bolts.
Tandem Seals (Standard)
Two seals. The upper seal operates inside the seal chamber. The upper seal faces are carbon against ceramic. The lower seal faces are silicon carbide against silicon carbide. Note that the 9706 motor is constructed with carbon/ceramic on both the upper and lower seals and is available in tandem style only.
Double Opposed Seals (Optional)
Two seals. Both seals are in a constant oil bath. The upper seal is carbon against ceramic. The lower seal face is silicon carbide against silicon carbide. Not for pump heads exceeding 80 feet TDH. Not available on 9706 motors.
NEMA 6, submersible air-filled, hermetically sealed, Class F insulation.
Single-phase voltages are 115 or 208-230 with auto-reset thermal and overload protection. Three-phase voltages are 208-230 or 460 volt. Single and three-phase 50 Hz models are also available.
Heavy cast iron with special integral cooling fins to permit trouble free operation while running in a non submerged condition.
Cast iron, air-filled, hermetically sealed, NEMA-6 design. 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 (Nitrile) rings for positive sealing. Viton (fluorelastomer) is available.
All models have 25 feet of neoprene jacketed cable as standard.
Permanently lubricated single-row, double-sealed. Oversized to handle radial and axial loads.
Series 300 stainless steel on 9709 and 9727 motor models. 9706 motor model has 416 stainless steel shaft.
