The PVV4-1X/113RA15RVC pump belongs to the PV Fixed Displacement Pumps series manufactured by Bosch Rexroth for hydraulic automation circuits that demand constant volume delivery. It displaces 112.7 cm³ per revolution, providing predictable flow with every shaft turn, and sustains a continuous working pressure of 175 bar so actuators receive stable force. At 1500 rpm it reaches 167 L/min, offering ample capacity for medium-size systems, while a top speed of 1800 rpm is permissible when the inlet is held at 1 bar absolute. The minimum operating speed is 600 rpm to keep internal bearings lubricated and avoid flow starvation. Clockwise rotation when viewed at the shaft aligns with most diesel engine drives, and the cylindrical drive shaft simplifies direct coupling to keyed hubs. Mounting is on an SAE-C flange, allowing quick attachment to standard bell housings.
The inlet and outlet interfaces are dimensioned to protect the pump against cavitation and excessive pressure drop. A maximum absolute inlet pressure of 2.4 bar guards against seal overload, whereas a minimum absolute inlet pressure of 0.83 bar defines the lowest suction condition that still maintains fluid continuity. Oil enters through an SAE 2 in suction port sized for low entry velocity and exits through an SAE 1 1/4 in pressure port that sits on the right side to match right-hand manifold layouts and reduce hose bends. FKM sealing withstands hot hydraulic oil and common additives, preserving service life under continuous duty. The unit weighs 23 kg, which fits within the load limits of typical engine adapters and permits one-person handling during installation.
