What is the difference between a centrifugal water pump and a submersible water pump?

Generally, the pump has a suction side and a delivery side. The atmospheric suction of the water service has a limit of approximately 26 feet of stumping level. And it decreases as you live at higher altitudes.

But in many applications, the suction power varies. When the pump is installed in the well, the water level varies greatly. This situation may be a better choice than jet pumps.

A submersible pump means a sealed motor. Although there is no entry of water. It is completely submerged in water. And its electrical connection is waterproof. The electrical connection is completed through a sealed cover. Packed with anti-fruit jelly or grease.

In submersible pumps, the suction port is usually submerged. Which means  the water completely covers in the suction port.

The pump is usually connected to the motor via a retractable shaft. Keep it as close as possible. But try to be slightly higher than the expected high water mark. If the water level is exceeded, the submerged motor will not cause any problems.

Use barbed wire to protect the inlets of open wells to prevent leaves, fish, frogs, and toads from entering.

This avoids the suction side restrictions of the centrifugal pump, such as air locks, bottom valves, air pockets, etc. Because the pump must sometimes be kept below the bottom. Provide hooks, tackles and chains to lift the motor for maintenance is also necessary.
