The submersible pump is a centrifugal pump. Because all stages of the pump end (wet end) and the motor are joined and submerged in the water, it has a great advantage over other centrifugal pumps. There is no need to recirculate or generate drive water as there is with jet pumps, therefore, most of its energy goes toward “pushing” the water rather than fighting gravity and atmospheric pressure to draw water.

A.Y. McDonald offers a full line of no-lead brass submersible pumps built for years of trouble free operation, with high-efficiency impellers and diffusers. These submersibles offer peak capacity performance in 5, 7, 10, 15, 20, and 25 gallons per minute (GPM). Other features include no-lead discharge head with a built-in check valve, and stainless steel shaft and coupling. All No-Lead Pumps come with a 1 1/4” discharge and sizes range from 1/3 to 2 horsepower (HP). Two wire models up to 1 1/2 horsepower (HP) or three wire models up to 2 horsepower (HP).
