PSV-PSRF-40HRM-66

The PSV-PSRF-40HRM-66 pump is manufactured by Bosch Rexroth for the PSV Variable Vane Pumps series and serves hydraulic automation systems that need adjustable delivery. As a variable volume vane design, it provides 30 GPM at 1750 rpm so actuators receive stable flow without wasting energy. A pressure compensator changes the displacement automatically to keep circuit pressure near the 2000 psi rating, preventing overloads. Right-hand rotation matches most clockwise prime movers for straightforward shaft coupling, while flange mounting fixes the housing firmly to a power-unit plate and resists vibration during continuous duty.

Rear ports arranged with flange connections bring both suction and pressure lines to the back face of the unit, reducing hose loops and easing cabinet layouts. Technicians can set the maximum displacement with a screw volume control that functions as a simple mechanical stop, eliminating the need for external pilot controls when fine-tuning flow limits. Viton seals withstand hot petroleum-based or synthetic fluids and protect the internal vanes from leakage over long service intervals. Together these features support accurate pressure and flow regulation in automated presses, molding machines, and other duty cycles that demand repeatable hydraulic performance.
