Mud Pumps

Rig Equipment

A mud pump is a heavy-duty pump used in drilling operations to circulate drilling fluid (commonly known as "mud") down the wellbore. It is a key component of the circulating system in both onshore and offshore drilling rigs.

The mud pump forces drilling fluid down the drill string and out of the drill bit nozzles at high pressure. This fluid then returns to the surface through the annular space (the gap between the drill string and the walls of the borehole). Use the link below to learn more about drilling mud and its use.

Mud pumps are typically reciprocating pumps, either duplex (two cylinders) or triplex (three cylinders), designed to handle the demanding and abrasive nature of drilling fluid. They are indispensable for maintaining an efficient and safe drilling operation. 

The mud pump output (volume) is controlled by the use of different size liners, a larger liner will provide an increase in fluid volume but will have a lower pressure where conversely a smaller liner will allow larger pump pressures but at a lower volume per stroke.
