How a submersible slurry pump works?

A submersible slurry pump operates on the same principle as every other centrifugal pump, creating a centrifugal force that moves the slurry using an impeller that rotates at high speed.

This impeller is connected to a motor designed to operate in a waterproof compartment while fully submerged. The slurry enters the pump through the inlet and, with the conversion of rotary energy into kinetic, is pumped out the discharge at pressure. Submersible slurry pumps are typically made of wear-resistant materials such as high chrome alloys to withstand the corrosive nature of the slurry they pump.

Submersible pumps eliminate suction piping or priming issues when pumping out of a tank or vessel below ground.
