PVV42-1X/113-068RA15DDMC

The PVV42-1X/113-068RA15DDMC pump is built by Bosch Rexroth within the PV Fixed Displacement Pumps series for hydraulic automation circuits that demand steady volumetric delivery. It turns clockwise, allowing direct coupling to engines or electric motors that follow the common right-hand rotation convention. Two internal pumping elements support different work sections: the cover side displaces 67.5 cm³ per revolution and the flange side displaces 112.7 cm³ per revolution so designers can assign separate flows to multiple actuators from one shaft. At 1500 rpm those sections supply 100 l/min and 167 l/min respectively, giving predictable throughput for machines that rely on synchronized motion. The unit sustains a continuous pressure of 175 bar, which protects cylinders and motors from pressure drop during long duty cycles. A maximum speed of 1800 rpm and a permitted minimum of 600 rpm define the usable speed window, letting system programmers adjust pump output with variable-speed drives without pushing the pumping group into cavitation or overspeed.

Installation follows established American standards; the housing carries an SAE-C 127-2 mounting flange and conforms to the SAE J744 flange style, so it bolts directly to most industrial gearboxes and bell housings without adapters. The cover side pressure port is sized at SAE 1 inch while the larger flange side outlet uses an SAE 1 1/4 inch connection, enabling each section to route its rated flow through appropriately dimensioned lines. A single 3 inch SAE suction port feeds both stages to minimize inlet velocity and reduce risk of aeration. NBR seals are fitted to resist typical hydraulic oils and maintain leakage control across the specified temperature range. With a mass of 34.5 kg, the pump can be handled by one technician using standard lifting eyes, yet it is heavy enough to damp vibration on the mounting surface. These interface features allow the pump to integrate into presses, injection machines, and other fixed-displacement drive systems with minimal adaptation.
