Features

PUMP FEATURES: Type VSSF pumps have cast iron casings with smooth waterway to insure maximum efficiency. Rabbeted construction insures complete alignment of the rotating element. The cast iron impeller is of non-clog design and is balanced prior to assembly.

MOTOR FEATURES: Motors are available for 1750 and 1150 R.P.M. operation with both single phase and three phase windings. Single phase motors are furnished with a separate capacitor box. All motors have prelubricated ball bearings.Explosion proof motors are also available. Motors are rated for intermittent duty in air at full load, continuous duty in air at reduced load, and, if furnished with modified frames, for continuous duty in air at full load. Shaft and fasteners are stainless steel. End brackets and frame are cast iron. All leads are epoxy sealed. Double seals provide protection for the electrical parts. If the outer seal fails, the inner seal protects the motor while water enters the oilfilled chamber. A moisture sensing probe detects the entry of water into the chamber and sends a signal to the appropriate alarm. Motors are furnished with 25-feet of power and control cable and grounding wire. The standard motors are rated for operation in 40 degrees C (104 F) water, but can be modified for higher ambient temperatures. Thermal protection is a standard feature.

FED-FLUSH FITTINGS: VSSF and VSSF-QD units are designed so that sewage entering the pit shall flow through stainless steel strainer baskets in the pump discharge pipes. Solids are retained in the baskets and the liquid continues through the pump casings into the pit. This prevents possible clogging of the pump casing and impeller by the solids. The solids are flushed into the discharge line during the pump discharge cycle and a control valve prevents backup into the house line. An overflow fitting allows liquid to flow directly into the pit during discharge cycles, if necessary.

QUICK-DISCONNECT FITTINGS (OPTIONAL): VSSF pumps can be fumished with Quick-Disconnect fittings (VSSF-QD) if desired. These fittings permit lifting of the pumps from the pit for inspection or service, without anyone entering the sewage pit and without disturbing the pump discharge pipes and electrical connections. The pump is lowered into the pit, held in position by its guide rail and automatically completes the discharge connection. The angled discharge mating flange is designed to assure a complete discharge seal.
