| Definition |
A mud pump that is so called because it has two cylinders, each containing a piston that moves back and forth inside a liner. One end of the pump, the fluid end, is concerned with intake and output of the fluid being pumped. Each cylinder is attached to two intake valves and two discharge valves. The movement of the piston causes the valves to act in pairs; both an intake of mud into the pump and a discharge of mud from the pump occur during each back-and-forth movement of the piston. For this reason the pump is described as double- acting.
