The PVV52-1X/193-055RA15DDMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and provides constant volume delivery for hydraulic automation tasks. It is built around SAE ports secured by UNC screws, so installers can attach common North American hydraulic fittings without adapters. A SAE-C mounting flange aligns the housing with standard prime movers, simplifying drivetrain layout. The cover side pressure connection is a SAE 1 in port located on the top at 0°, which allows a straight, short high-pressure line toward downstream components. NBR seals are fitted to contain oil compatible with this elastomer and to minimize leakage across the service life. At 46 kg, the unit can be lifted by a single hoist and supported by typical pump brackets. Clockwise rotation matches many diesel engines and electric motors, avoiding the need for gear reversers. The pump holds a continuous pressure rating of 175 bar so circuit designers can size actuators for steady medium-pressure operation.
The cover side displacement is 55.2 cm³ per revolution, yielding 80 L/min at 1500 rpm and giving predictable flow for auxiliary functions. The flange side section provides 193.4 cm³ per revolution, which increases output to 285 L/min at the same speed and supports large volume consumers in the same circuit. A SAE 1 1/2 in pressure outlet on the flange side handles the higher flow while limiting line velocity, and a SAE 3 1/2 in suction port reduces inlet restriction to avoid cavitation. The pump can run at speeds up to 1800 rpm when inlet pressure is at least 1 bar, extending its usable range on variable-speed drives. These parameters allow the two-stage assembly to deliver balanced flow to multiple loads without adding separate pumps.
