Centrifugal pump is the machine which transports mud or water to the drilling hole. Centrifugal pump is a important part of the drilling mechanical equipment. The main function of the centrifugal pump is taking the mud enter into the downhole with the drilling head.

Function

Cooling the drilling head
Washing drilling tools
Fastening the wall, drive drilling
Carry the rock debris back to the ground
