About Piston Pumps and Plunger Pumps

Piston pumps and plunger pumps are reciprocating pumps that use a plunger or piston to move media through a cylindrical chamber. The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. Piston pumps and plunger pumps are also called well service pumps, high pressure pumps, or high viscosity pumps.


Products & Services Related to Piston Pumps and Plunger Pumps

Centrifugal Pumps
Centrifugal pumps consist of a set of rotating vanes, enclosed within a housing or casing, that are used to impart energy to a fluid through centrifugal force.
Condensate Pumps
Condensate pumps are used to collect and transport condensate back into a steam system for reheating and reuse, or to remove unwanted condensate from an HVAC or appliance collection pan.
Diaphragm Pumps
Diaphragm pumps use a diaphragm that moves back and forth to transport liquids from one place to another.
Drum Pumps
Drum pumps are used to transfer materials from a container into a process or other container. They may be electrically, hydraulically, or pneumatically powered depending on the working environment or application.
Gear Pumps
Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.
Metering Pumps
Metering pumps are precision pumps, which dispense an exact amount of material. They are used in a variety of chemical dosing and metering applications.
Screw Pumps
Screw pumps are rotary, positive displacement pumps that have one or more screws to transfer fluids or materials along an axis.
