A quintuplex is a classification of mud pump commonly used for oil drilling. The primary purpose of a mud pump is to circulate the mud, also called drilling fluid, during drilling operations. It works by forcing drilling fluid down the hollow drill string and back up through the annulus. Quintuplex gets its name because it has five plungers that force the drilling fluid into the drill string.

Mud pumps can be divided into two main sections: the power end, which houses the crankshaft and other parts that produce the power; and the fluid end, which converts the reciprocating action of the power end into suction and discharge power for the drilling fluid. Depending on the application, mud pumps can create up to 7,500 pounds per square inch of pressure.
In addition to quintuplex pumps there are also duplex pumps with two plungers, triplex pumps with three plungers, and hex pumps with six plungers. Duplex pumps have largely been replaced by triplex pumps. However, quintuplex pumps and hex pumps are preferred because of their smoother operation, which results in reduced noise during operation. This facilitates easier measurement while drilling and logging while drilling.
