The PVV21-1X/055-036RA15DDMB pump is produced by Bosch Rexroth for the PV Fixed Displacement Pumps series and supplies constant hydraulic flow to automation circuits that require dual outlet operation. The unit rotates clockwise, matching standard right-hand drive shafts in power-take-off arrangements. A SAE-B mounting flange simplifies direct attachment to industrial engines or electric motors, while SAE port connections with UNC screws let technicians fit common hose ends without extra adapters. Both the cover and flange pressure outlets sit on the top at 0°, keeping supply lines aligned for overhead routing inside compact power packs. The cover side displacement is 36.4 cm³ per revolution and the flange side displacement is 55.2 cm³ per revolution, so designers can obtain different flow rates from a single drive.
The cover section withstands continuous pressure up to 210 bar, whereas the flange section is rated for 175 bar, allowing each circuit to match its operating load. At 1500 rpm the cover outlet provides 53 l/min and the flange outlet reaches 80 l/min, delivering stable flow for simultaneous actuator groups. Maximum drive speed is 1800 rpm at a 1 bar inlet pressure, and operating above this limit increases cavitation risk. Approved fluid temperatures range from −10 °C to +70 °C, accommodating year-round service with standard mineral oils. The complete assembly weighs 20 kg, which supports installation on mobile equipment frames without additional structural reinforcement.
