A Mud pump is a reciprocating plunger device designed to circulate drilling fluid down the drill string and back up the annulus.
Mud pumps come in a variety of sizes and configurations but for the typical petroleum drillin
rig, the triplex (three piston/plunger) mud pump is the pump of choice. Duplex mud pumps (two piston/plungers)have generally been replaced by the triplex pump, but are still common in developing countries. A later development is the Hex pump with six piston/plungers.
