About Hydraulic Pumps

Hydraulic pumps deliver high-pressure fluid flow to the pump outlet. Hydraulic pumps are powered by mechanical energy sources to pressurize fluid. A hydraulic pump, when powered by pressurized fluid, can rotate in a reverse direction and act as a motor.  Operating specifications, housing materials, and features are all important specifications to consider when searching for hydraulic pumps.

Pump type and pump stages are the most important operating specifications to consider when searching for hydraulic pumps.  Choices for hydraulic pumps types include axial piston, radial piston, internal gear, external gear, and vane.  An axial piston pump uses an axially-mounted piston to pressurize fluid.  Mechanical motion from the pump's power source moves the piston through a chamber, pressurizing the fluid it comes in contact with.  A radial piston pump uses pistons mounted radially about a central axis to pressurize fluid.  An alternate-form radial piston motor uses multiple interconnected pistons, usually in a star pattern.  The hydraulic pumps’ power source causes the pistons to move, forcing the pistons through the chambers and pressurizing fluid.  An internal gear pump uses internal gears to pressurize fluid.  The pump's power source causes the internal gears to turn, which forces fluid through the pump outlet.  An external gear pump uses external gears to pressurize fluid.  The pump's power source causes external gears to turn, which forces fluid through the pump outlet.  A vane pump uses a vane to pressurize fluid.  The pump's power source causes the vane to rotate.  As the vane rotates, blades on the vane push fluid out the pump's outlet.  Pump stages include single stage, double stage, triple stage, and four or more pump stages.

Products & Services Related to Hydraulic Pumps

DC Powered Pumps
DC powered pumps use direct current from motor, battery, or solar power to move liquids such as acids, chemicals, lubricants and oil, as well as water, wastewater, and potable water.
Dosing Pumps
Dosing pumps are low-volume fluid pumps with controllable discharge rates used to inject additives into the mixing or pumping system.
Magnetic Drive Pumps
Magnetic drive pumps are sealless pumps that use a coaxial magnetic coupling to transmit torque to an impeller. A standard electric motor drives a set of permanent magnets that are mounted on a carrier or drive assembly.
Plastic Pumps
Plastic pumps are designed to move fluids that would corrode or damage other types of pumps. They provide broad chemical resistance and are less costly and lighter in weight than metal pumps.
Positive Displacement Pumps
Positive displacement pumps use a mechanical force such as gears, bladders, pistons, plungers or diaphragms to push liquid through and out of the pump.
Sanitary Pumps
Sanitary pumps are used to transport and meter solutions, slurries, and colloids of food and agricultural materials in operations such as food processing that require cleanliness. There are four basic types of sanitary pumps: centrifugal, positive displacement, jet, and airlift.
Syringe Pumps
Infusion or withdrawal syringe pumps provide high pressure and high accuracy for applications such as high performance liquid chromatography (HPLC).  Used to deliver precise amounts of fluid at specific time intervals.
