	I PUMPS J SERIES

	EFFICIENT, DEPENDABLE SOLIDS-HANDLING SEWAGE PUMPS

	UNIQUE MOISTURE SWITCH Protects motor should any leakage penetrate the motor housing, thus avoiding motor damage. CLASS F INSULATION Air-filled squirrel cage motor. EXTERNAL AXIAL ADJUSTMENT Impeller clearance adjusts quickly and easily by turning three external screws. No disassembly or replacement parts are necessary.	PATENTED CABLE ENTRY SEAL Prevents moisture from entering the motor. Unique cable grip prevents cable from dislocating and allows easy cable replacement with common hand tools. No potting is required. THREE THERMAL SWITCHES Imbedded in each stator to protect the motor from overheating. RELIABLE COOLING SYSTEM With the cooling jacket, cooled water is taken from the liquid to be pumped and is circulated around the motor. The pump out vanes on the back side of the impeller, along with the close clearances, keep solids and debris from entering the circulation ports. The heat from the motor is transferred to the seal housing which is cooled by the liquid being pumped. DOUBLE MECHANICAL SEALS Tandem seals located in oil cavity between impeller and motor provide double protection against moisture entering the motor. Seals have sliding rings with lower seal of silicon carbide surfaces for long life. Oil chamber ensures efficient cooling of seals.

	AUTOMATIC CONNECTION TO THE DISCHARGE PIPE Slide rail pumps are lowered into the sump along two guide rails and are connected automatically to the base plate and released automatically when the pump is lifted. The slide rail guide shoe, which is equipped with an integral neoprene seal ring, provides 100% tight connection between the pump and the discharge flange. The seal ring is easily replaced in the event of wear. There is no need to enter the wet well or replace base plate.
