Plunger Pumps

Plunger pumps are a type of positive displacement pump where the high-pressure seal is stationary and a smooth cylindrical plunger slides through the seal. This makes them different from piston pumps and allows them to be used at higher pressures.

Plunger pumps component materials are chosen for wear and contact with the media type.

Component materials include bronze, brass, steel, stainless steel, iron, nickel alloy, or other material. For example, plunger pumps that function in general service or oil service applications often have an iron cylinder and plunger.

The plunger, discharge valves, and suction valves come in contact with the media type transferred, and material choices are based on the fluid transferred. In power applications where continuous duty plunger pumps are needed, solid ceramic plungers may be used when in contact with water and oil, but may not be compatible for use with highly acidic media types.
