The PVV2-1X/055RA15LMB belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies constant flow for hydraulic automation circuits. It delivers 55.2 cm³ per revolution so system designers can predict pump output precisely. Clockwise rotation aligns with right-hand drive arrangements, and a cylindrical "A" drive shaft simplifies direct coupling to electric motors. The SAE J744 mounting style with an SAE-B (101-2) flange lets the unit attach to common power take-off pads without adapters. Suction and pressure ports follow SAE sizing with UNC threads, enabling the use of standard hose fittings during installation. The suction side is a 1-1/2 in connection, while the pressure side is 1 in to maintain proper velocity ratios. The pressure port is located on the left, 90° from the inlet, which keeps hose runs compact inside a manifold block. An NBR seal resists petroleum-based fluids, and the complete assembly weighs 14.8 kg for manageable handling during maintenance.
The pump sustains 175 bar continuous outlet pressure, supplying actuators with stable energy for clamping, pressing, or steering functions. A minimum inlet pressure of 0.83 bar absolute must be maintained to prevent cavitation at the suction side. At 1500 rpm it produces a maximum flow of 80 l/min, giving designers a clear benchmark for heat exchanger sizing and return-line capacity. When inlet pressure is held at 1 bar, the unit can be driven up to 1800 rpm, extending its flow range for intermittent high-demand cycles. It may also run as low as 600 rpm, allowing slow actuator movement during setup or positioning. These speed limits define a broad operating window so one pump can cover diverse machine modes without risking internal wear or flow instability.
