Product Overview
The Rexroth PVV4-1X/082RA15DMC (Material Number: R900931548) is a high-performance fixed displacement vane pump engineered for demanding industrial hydraulic systems. Operating on the proven rotary vane principle, this pump features a precision-ground rotor with radially guided vanes that sweep against a stationary cam ring to create a continuous, uniform pumping action. With a nominal displacement of 82 cm³/rev, the PVV4 series delivers consistent flow output independent of system pressure fluctuations, making it an ideal choice for applications requiring stable volumetric delivery and low pulsation. The “1X” designation indicates the first generation series, while “RA15” defines the specific cam ring geometry and pressure rating. This pump is widely deployed as a reliable power source in centralized hydraulic power units, offering exceptional suction performance and quiet operation compared to gear or piston alternatives.
