Submersible Water Pumps

What is a submersible water pump?

A type of submersible pump that is used specifically to move water. The pump is used for many different applications and commonly classified as well pumps, borehole pumps, pond pumps, pool pumps, and fountain pumps. For many applications, operators have the option to choose between a submersible pump and a vertical turbine pump or jet pump.

How do they work?

Submersible water pumps operate from beneath the surface of the water. Because of this, the mechanical components of the pump must be protected from the fluids, usually by multiple, redundant mechanical seals. Most are considered centrifugal pumps that include a motor that is hermetically attached to the pump end and able to operate submerged in the fluid. When activated, the pump uses centrifugal force to both draw the water through the intake and send water upward to the surface level. Because the pumping chamber is submerged and always filled with water, they are self-priming.

Submersible pumps usually aren't very powerful, and there must be a relatively short distance between the pump and the place where the water is being sent. To increase the power, booster pumps or multistage pumps may be used.
