PSV-PNAF-25ERM-66

The PSV-PNAF-25ERM-66 variable vane pump is supplied by Bosch Rexroth as part of the PSV Variable Vane Pumps series and is intended to maintain stable hydraulic power in automated machinery. It employs a pressure compensator to match output flow to system demand and avoid unnecessary energy use. The unit is flange mounted, allowing a rigid connection to the prime mover, and the hydraulic lines enter through side ports that share an SAE straight thread profile to simplify hose selection. A right-hand rotation shaft suits standard clockwise drives, while a rated flow of 20.2 GPM at 1800 rpm supports moderate actuator speeds in mobile or industrial circuits.

The pump sustains continuous service at 1000 psi, supplying pressure levels common to light-duty press, clamp, or steering functions. Fluid enters through an SAE 24 inlet port with a 1 7/8-12 thread and exits via an SAE 16 outlet port with a 15/16-12 thread, so line sizing is fixed for predictable pressure loss. Viton seals are installed to resist mineral oil and elevated temperature, extending service life under cyclic duty. Because no external volume control mechanism is provided, flow trimming relies solely on the internal compensator. These features integrate into hydraulic automation layouts that require dependable delivery without additional control hardware.
