AD Type Diesel Engine Plunger 131150-2420 Element A812 plunger suit for DAEWOO 300-5

Rotary piston and plunger pumps use a crank mechanism to create a reciprocating motion along an axis, which then builds pressure in a cylinder or working barrel to force gas or fluid through the pump. The pressure in the chamber actuates the valves at both the suction and discharge points. Plunger pumps are used in applications that could range from 70 to 2,070 bar (1,000 to 30,000 psi).
