Piston pump

Piston pumps work to reduce a volume by a fixed crank-driven piston within a cylinder.

A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston.[1] Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate. Piston pumps can also deal with viscous media and media containing solid particles.[2] This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems
