How Electric Plunger Pump Manufacturers' Piston Pumps Work
Piston pumps consist of a reciprocating piston that fits tightly within a cylinder with seals. The piston is connected to a rotor that forces it to move up and down in the cylinder. As the piston reciprocates up and down, it draws water into the cylinder through the intake valve. When the piston is pushed back through the cylinder, it pushes the water through the outlet valve.
The piston is connected to a seal that moves in unison with the piston. For this reason, piston pumps tend to wear out quickly and cannot generate high pressures. Therefore, piston pump pressure washers are best suited for residential use where vehicles, fences, and siding are cleaned.
How a plunger pump works
Unlike the piston, which is tightly mounted in the cylinder, the plunger is loosely mounted. When the plunger moves up and down, negative and positive water pressure is generated in the cylinder. It sucks water through the inlet valve and discharges it through the outlet valve.
The seal is fixed, which allows a plunger pump to generate higher pressures than a piston pump. Plunger pumps are ideal for high pressure industrial applications such as graffiti removal and washing or cleaning of heavy industrial vehicles.
