Different types of piston pumps

Fixed displacement radial piston pumps for high torque hydraulic applications at low speeds.

Hydraulic Pumps

What is a radial piston pump and why do you need it?

Radial piston pumps are used in applications that involve high pressures (operating pressures above 400 bar and up to 700 bar), such as presses, machines for processing plastic and machine tools that clamp hydraulics. Radial piston pumps are the only pumps capable of working satisfactorily at such high pressures, even under continuous operation.

Radial piston pumps are available in two different configurations. With eccentric cylinder block, the piston rotates within the rigid external ring. Eccentricity determines the stroke of the pistons. Or, with an eccentric shaft, the rotating eccentric shaft causes radially-oscillating piston movements to be produced. Most models have an odd number of pistons to reduce the flow pulsation.
