A typical pump should not be used while fully submerged in deep water. For underwater applications, a submersible pump should be used.
Mechanical seals prevent water from entering the motor. These seals allow the device to operate beyond typical above-ground applications.
Submersible (or “submergible”) pumps can be used in a variety of applications. The most common use is to pump well water.
For people living in rural areas that are unable to access city water, water wells are a good alternate source of clean water. A submersible well pump can be placed down into the well, pushing the water upward.
It is recommended that a stainless steel or thermoplastic pump is chosen to resist corrosion. Proper attention must be given to the horsepower of a pump, as this element factors into the volume and speed of the water flow.
Submersible pumps are known for their reliability, often lasting for 20 to 25 years without requiring maintenance. They are better applied in a deep well; when placed in a shallow well, silt and sand can shorten the life of the pump.
A good non-clog, corrosion-resistant submersible pump can also be used to pump wastewater and sewage. Typical wastewater pump applications are: sewage systems, pollution control, industrial dewatering, and municipal systems.
