Myers SP Series Sewage Pumps Buyers Guide & Review

The Myers SP series of submersible sewage pumps is specifically designed to meet the demands of handling wastewater and sewage in residential and commercial building applications. The 2 inch NPT discharge pump (3 inch discharge optional) is available with a powerful 1/2 horsepower motor, in both automatic and manual configurations; and can handle capacities up to 150 gallons per minute and heads to 28 feet.

The SP series features a heavy-duty cast iron construction that provides durability in rugged applications, as well as assists in dissipating heat from the motor, for cooler operation. It is also available in an all bronze model. The pump’s non-clog, non-corrosive, cast iron impeller, which is threaded to a nickel plated steel shaft, provides long life even in demanding applications. This series is capable of handling spherical solids up to 1-1/2 inches and lint. The SP series also features precision, carbon and ceramic-faced mechanical shaft seals that are extensively lapped, providing for a long, leakproof life.

The 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.

Water level is controlled on automatic models by Myer’s proven diaphragm type pressure switch, which is sealed in a water tight thermoplastic housing. Double diaphragm construction provides added protection by preventing liquid or foreign matter from entering switch.
