The PVV52-1X/139-046RJ15UUMC pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series. It delivers a fixed hydraulic output for automation loops that require predictable flow. The unit rotates clockwise, matching common right-hand prime movers, and mounts through an SAE-C flange so it drops directly onto standardized housings. Its drive shaft uses an SAE-C 1 1/4-inch, 14-tooth, 12/24 DP spline that transmits torque without backlash under pulsating loads. The cover side displacement is 45.9 cm³ per revolution, providing medium-volume delivery to secondary circuits; at 1500 rpm this side reaches a maximum flow of 70 L/min. The pressure port for the cover side sits on the bottom, 180° from the inlet, which keeps pressure and suction lines parallel. This port is sized at 1 inch SAE, while the suction connection measures 1 1/2 inch SAE to limit inlet velocity. NBR sealing material protects the interface against common mineral oils.
Operating pressure is limited to 175 bar continuously, allowing the pump to serve medium-pressure manifolds without fatigue. The flange side displacement increases to 138.6 cm³ per revolution so that high-demand actuators receive greater volume, and its flow peaks at 203 L/min at 1500 rpm. The flange side pressure outlet is also positioned on the bottom, 180° from the inlet, giving the installation identical routing on both stages. A maximum speed of 1800 rpm at a 1-bar inlet permits high throughput when reservoir conditions are favorable, while a minimum speed of 600 rpm maintains internal lubrication during idle cycles. The assembly weighs 46 kg, a figure that guides bracket design and vibration isolation for mobile or stationary frames.
