S37 Submersible PumpSubmersible Pumps

Irving's Plumbing distributes submersible pumps for a variety of applications. A submersible pump is a water pump designed to be fully immersed within a tank or storage water container. The pump's motor is usually sealed in oil-filled cavity protected from contacting the water. A submersible pump is used to move water or waste water from a lower pressure area to higher pressure area, and overcomes this difference in pressure by adding energy to the process using a motorized pumping system.

Main Features
The most important features to consider when choosing a submersible pump includes its 1) horsepower rating, 2) its maximum discharge flow - the flow the pump is designed to generate, 3) the maximum discharge pressure, the pressure the pump is meant to produce, and 4) the size of the discharge outlet connection.

Applications
Submersible pumps have a number of distinct applications: pumping large solids or grinding solids to smaller sizes, to moving wastewater at large flow rates or high pressures, to simply pumping up water off the floor or the bottom of a tank. Depending on the design of the pump, some can be used for handling sewage, for moving solids like sand or moving water in an irrigation system.

We offer the following three models from Liberty Pumps: S37 Series | 240 Series (247) | 250 Series (257)
