The submersible solids handling sewage pump operates under water. The pump is efficient, quiet in operation, safe to install, and performs long and reliably. The submersible wastewater pump is used primarily for wet-pit sewage lift stations and for industrial sump or process effluent applications. A common use for small pumps is to move effluent from tank to disposal in septic tank systems. Large and small units are used in a variety of ways in the home, farm, motel, school, marine, commercial building, industrial plant, and municipal sewage and stormwater systems.
Millions are in daily use.
The submersible wastewater pump came to the United States in about 1955. Growth of the submersible for wastewater pumping has since been dramatic, as an increasing number of specifiers and users learned of its advantages. There are two classes of submersibles. Larger submersibles are discussed in this article. They are used in municipal and industrial applications for pumping sewage and all types of industrial wastewater.
