Plunger pumps are used in pressure washers to create high-pressure water jets that clean, degrease, or descale surfaces. Plunger pumps work by moving a reciprocating plunger back and forth, which creates suction and forces water through valves.
Here are some features of plunger pumps:
How they work
Plungers fit loosely in a cylinder, unlike pistons that fit tightly. The plunger's movement creates negative and positive water pressure, which sucks water in through the intake valve and forces it out through the outlet valve.
