A mud pump also is called a slush pump.A large, reciprocating pump that circulates drilling mud in rotary drilling. The duplex (two-cylinder) or triplex (three-cylinder) pump draws mud from the suction mud pit and pumps the slurry downhole through the drillpipe and bit and back up the borehole to the mud settling pits. After the rock cuttings drop out in the settling pit, the clean mud gravitates into the suction pit where it is picked up by the pump's suction line. In rotary drilling there are at least twin mud pumps, sometimes more. In case of a breakdown or other necessary stoppages, another pump can be immediately put on line.
