Mud pump is used to deliver flushing fluid (mud or clean water) to the drilling rig during geological drilling, and is used in conjunction with a 200-500 meter hydrological well drilling rig.

The mud pump is a horizontal reciprocating double cylinder double acting piston pump that uses variable speed to change displacement and pressure for selection during use.

The main body of the mud pump consists of two parts: the crankcase and the pump head. The function of the crankcase is not only to decelerate, but also to convert rotary motion into reciprocating motion. The pump head is a mechanism that directly absorbs and discharges water.
