What is a Submersible Well Pump?

A submersible pump is a pump that can be fully submerged in water. The motor is hermetically sealed and close-coupled to the pump’s body.

A submersible pump pushes water through your water system by converting rotary energy into kinetic energy, then into pressure energy. This is done by the water being pulled into the pump: first in the intake, where the rotation of the impeller pushes the water through the diffuser. From there, the water rises to the surface.

Benefits of a Submersible Well Pump

No Priming Required: The major advantage to a submersible pump water system is that it never has to be primed, because it is already submerged. Water pressure pushes the water into the pump, thus “saving” a lot of the pump’s energy, making the submersible water system more efficient.
Quiet Operation: Located beneath the water, these pump are operate quietly.
No Cavitation: The fully submerged design eliminates cavitation, which can damage other pump types.

What to Consider:

The seals can become corroded with time. When that happens, water seeps into the motor, rendering it useless until it is repaired. Also, that seal makes the submersible pump a bit difficult to get into for repairs.

One pump does not fit all uses. Single stage pumps are used for most home and light industrial pumping. This includes aquarium filters, sewage pumping, or sump pumps for drainage. Multiple stage pumps are used for anything underground, such as water wells. Also, pumps are designed to work with thin liquids like water, or thick ones like sewage.

If it is used out of water, it can overheat. The water around a submersible pump actually helps to cool the motor. Caution must be used with submersible pumps; they must be fully submerged.

Choosing the Right Submersible Well Pump

A number of variables determine the size and type of pump in any given well, including:

Well yield
Depth
Water system
Delivery pressure
Elevation of delivery point

Additionally, because electricity costs money and water supplies have limitations, it's wise to size pumps for electrical AND water efficiencies. Finally, there are three standard pump types for most residential and small irrigation projects (larger pumping systems, such as systems serving farms & cities, tend to use commercial pumps).
