PSV-PNAF-10HRM-66

The PSV-PNAF-10HRM-66 pump belongs to the PSV Variable Vane Pumps series produced by Bosch Rexroth for hydraulic automation. It supplies adjustable flow by means of a variable volume Silentvane cartridge that keeps operating noise low while allowing displacement change during every shaft turn. Output is governed by a pressure compensator, and its two-stage layout first opens quickly to meet sudden load demand and then trims flow to stabilize pressure. A continuous working limit of 2000 psi supports medium-pressure actuation circuits. The casing attaches with a flange mount so alignment to the prime mover is fixed, and right-hand rotation matches standard motor direction.

Side ports drilled with SAE threads let piping approach directly from the reservoir or manifold and help maintain compact installations. Because dedicated volume control is absent, flow variation depends solely on the internal compensator reacting to system pressure rather than a separate manually set device. Viton sealing elements resist common hydraulic oils and higher temperature excursions, reducing downtime from leakage. Internal features are defined by design revision 66, ensuring parts interchangeability for this release. The overall arrangement provides a regulated source of hydraulic flow while minimizing external components in automated machinery.
