adj: in reference to a mud pump, the action of the piston moving mud through the cylinder on both its forward and backward stroke. Compare single-acting.

n: a common reciprocal pump with two hydraulic cylinder ,the pump will complete two operations of fluid-incoming and fluid-outcoming when the piston does an alternating motion

n: a rotational bumper for drilling or fishing which can smack up and down alternately

n: a reciprocating pump with two pistons or plungers and used extensively as a mud pump on drilling rigs.

n: A reciprocating positive displacement pump having two pistons that are double-acting. Used as the circulating pump on some older drilling rigs.

a type of pump with two, dual acting pistons.

n: a large, high-pressure reciprocating pump used to circulate the mud on a drilling rig. A typical mud pump is a single- or double-acting, two- or threecylinder piston pump whose pistons travel in replaceable liners and are driven by a crankshaft actuated by an engine or a motor. Also called a slush pump.

n: a large reciprocating pump used to circulate the drilling fluid down the well.both duplex and triplex pumps are used with replaceable liners. mud pumps are also called slug pumps

primary mud circulation pumps on the rig.

n: a reciprocating pump for circulating drilling fluids. It operates through cranks and connecting rods by power supplied to its crankshaft from an electric motor or internal-combus- tion engine. It may be a duplex (with two cylinders) or a triplex (with three cylinders). Some mud pumps have double-acting pistons, and some have single-acting pistons that function as plungers.

adj: the action of a mud pump piston cylinder moving mud only on its forward stroke. Compare double-acting.
