What is a piston pump and for which hydraulic application do you need it?

Hydraulic piston pumps can handle large flows at high hydraulic system pressures. The piston pump is a hydraulic pump that delivers optimum efficiency and reliability while maintaining a compact size with a high power density. In these pumps, the pistons accurately slide back and forth inside the cylinders that are part of the hydraulic pump. The pistons' sealing properties are excellent, making it possible to operate at high pressures with low fluid leakage.

Piston pumps are the hydraulic pumps with the highest pressure rating and best overall efficiency.

Due to low fluid leakage, hydraulic piston pumps operate at very high volumetric efficiency levels. The plungers may consist of valves at the suction and pressure ports or with input and output channels. Piston pumps with valves at the ports are better suited to operate at higher system pressures due to better sealing characteristics. Applications are mobile and construction equipment, marine auxiliary power, metal forming and stamping, machine tools and oil field equipment.
