PSV-SNSF-20HRM-110/115-56

The PSV-SNSF-20HRM-110/115-56 belongs to the PSV Variable Vane Pumps series from Bosch Rexroth and delivers adjustable hydraulic power for automated machinery. It is a variable-volume vane unit that supplies 15.2 gallons per minute when driven at 1,800 rpm, providing steady flow for cylinders and motors without excessive heat generation. A maximum working pressure of 2,000 psi allows it to serve medium-pressure circuits common in machine tools and presses. Right-hand rotation matches standard electric motor direction, while the subplate mounting style anchors the housing to a manifold block so service work can be performed without disturbing pipe runs.

Control is handled by a solenoid two-pressure mechanism that shifts the pump between two preset pressure levels for energy savings during idle phases. No external volume adjustment is fitted, so flow changes depend solely on the internal displacement system. Design code 56 identifies the precise manufacturing revision used for replacement ordering and interchangeability. Viton sealing elements resist synthetic and high-temperature fluids, extending service life in demanding plant environments. Together, these characteristics support reliable hydraulic automation where compact installation and controlled pressure shifts are required.
