Hydraulic Pump is a water pump that uses the kinetic energy of flowing water to force a small fraction of that water to a reservoir at a higher level. It is used as a device to move liquids in hydraulic drive systems.

Hydraulic Pump Types

Gear pumps uses meshed gears that rotate and move liquid through a hydraulic system.

Gerotor Pumps is a variation of gear pumps, with internal teeth of optimized design. For medium pressure pump, the efficiency and noise level are very good.

Rotary vane pumps has higher efficiencies than gear pumps, but are also used for mid pressure up to 180 bars general. A positive-displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity.

Screw Pumps are rotary, positive displacement pumps that can have one or more screws to transfer high or low viscosity fluids along an axis. One example of classic screw pumps is Archimedes screw pump which is still used in irrigation and agricultural applications.

Bent Axis Piston Pumps has a rotating cylinder which is driven by shaft which is arranged at an angle to the cylinder axis.

Axial Piston Pumps is a positive displacement pump that has number of pistons in a circular array within cylinder block. It can be used as stand alone pump, automotive air conditioning compressor or as hydraulic motor.

Radial Piston Pumps is a variable-displacement pumps that can produced a very smooth flow under extreme pressure.

Peristaltic Pumps is a type of positive displacement pump used for pumping a variety of fluids. It is usually used to pump sterile or aggressive fluids.
