The PVV4-1X/113RD pump belongs to the PV Fixed Displacement Pumps series and is produced by Bosch Rexroth for hydraulic automation circuits where a constant displacement unit is required. It delivers 112.7 cm³ of fluid per revolution, so flow is directly proportional to shaft speed and simplifies volume calculations. When driven at 1500 rpm it provides a flow of 167 l/min, matching medium-size actuator demands. The pump can run as slow as 600 rpm for low-duty cycles and up to 1800 rpm at a 1 bar inlet, giving users a wide operating window. Clockwise shaft rotation must be observed to maintain correct internal porting. A SAE-C mounting flange standardizes attachment to common power take-offs. The unit is intended for HLP mineral oil specified in DIN 51524-2, and it requires a minimum viscosity of 13 mm²/s to keep hydrodynamic lubrication stable.
Continuous system pressure may reach 175 bar, allowing the pump to supply moderate-pressure mobile or industrial circuits without overload. Suction conditions should not drop below an absolute inlet pressure of 0.83 bar so cavitation is avoided during high flow demand. The permitted fluid temperature rises to 70 °C, enabling operation in warm return-line environments. Pressure delivery leaves through a SAE 1 1/4 in port that sits on the top side in line with the inlet orientation, simplifying rigid tube routing in compact manifolds. Fluid entry is through a larger SAE 2 in suction port to keep inlet velocities low. Acceptable contamination levels are limited to ISO 4406 code 20/18/15 to protect the sliding surfaces. The pump weighs 23 kg, which influences support bracket sizing when mounted on machinery.
