Submersible Sewage Ejector Pump, SP50 (HYDROMATIC PUMP 10' CORD, 1/2HP)

HYDROMATIC PUMP 10' CORD, 1/2HP|Hydromatic's SP50 submersible pump is specifically designed to meet the demands of handling wastewater and sewage in residence and commercial building applications. The 2 inch NPT discharge pump has a powerful ½ horsepower motor, in both automatic and manual configurations; and can handle capacities up to 150 gallons per minute and heads to 29 feet. It features a heavy-duty cast iron construction that provides durability in rugged applications, and assists in dissipating heat from the motor, for cooler operation. The pump’s non-clog, non-corrosive, thermoplastic impeller, which is threaded to a stainless steel shaft, provides long life even in demanding applications; and can handle up to 1-1/2 inch spherical solids and lint. The SP50 also features precision, carbon- and ceramic-faced mechanical shaft seals that are extensively lapped, providing for a long, leakproof life. The SP50’s oil-filled motor provides superior cooling characteristics, allowing the motor to run cool and quiet for years. This oil-filled design also provides permanent lubrication of the shaft bearings, minimizing maintenance and extending the service life of the pump. In addition, to protect against overheating, the motor windings contain an automatic reset thermal overload (1 ø). Water level is controlled on automatic models by Hydromatic’s proven diaphragm type pressure switch, which is sealed in a water tight cast iron housing. Double diaphragm construction provides added protection on preventing liquid or foreign matter from entering switch.
