MPA1002 air pump

Piston pumps and plunger pumps are reciprocating positive displacement pumps that use a plunger or piston to move media through a cylindrical chamber.They use a mechanism (typically rotational) 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. Specifically, air flow rate is proportional to motor speed, piston stroke, and piston diameter.
