Applications & Use Cases

The Rexroth PVQ52 hydraulic vane pump serves critical roles across diverse industries and operational environments:

Marine Hydraulic Systems

Commercial vessels, offshore platforms, and port equipment rely on the PVQ52 for steering gear, winch drives, cargo handling systems, and deck machinery. The pump's robust construction resists the corrosive effects of saltwater environments while delivering the high flow rates necessary for large hydraulic cylinders and motors found in marine applications.

Industrial Presses & Metalworking

Hydraulic presses, stamping equipment, and metal forming machines utilize the PVQ52's high-pressure capability to generate the forces required for bending, punching, and drawing operations. The pump's consistent flow characteristics ensure uniform cycle times and repeatable part quality.

Mobile Equipment

Construction machinery, mining equipment, and agricultural vehicles benefit from the PVQ52's power density and reliability. The vane pump technology handles the shock loads and contamination typical of mobile hydraulic systems while maintaining consistent performance across varying speed and temperature conditions.

Material Handling

Forklifts, cranes, and conveyor systems employ the PVQ52 for lift, tilt, and travel functions. The pump's efficiency reduces fuel consumption in engine-driven systems and minimizes electrical load in motor-driven installations.

• Proven Track Record: The PVQ series has accumulated millions of operating hours across diverse applications, validating its design and construction

Compatibility & Integration

The Rexroth PVQ52 vane pump integrates with standard hydraulic systems using mineral oil-based fluids with viscosities between 10 and 100 mm²/s. The pump's SAE flange mounting and splined shaft interface with standard bell housings and couplings, simplifying installation in both new designs and retrofit applications.

System designers should ensure adequate inlet conditions to prevent cavitation, maintaining inlet pressure above 0.8 bar absolute at operating temperature. Proper filtration with a return line filter of ß10 ≥ 75 is recommended to maximize service life. For cold start conditions, pump speeds should be limited until fluid viscosity drops into the normal operating range.

Hydraulic System Design Considerations

Integrating the Rexroth PVQ52 vane pump into a hydraulic system requires careful attention to several design parameters that directly affect performance and service life. The inlet conditions deserve particular attention, as vane pumps are more sensitive to inlet restrictions than piston or gear pumps. The reservoir should be positioned to provide a positive head to the pump inlet, with suction line velocity maintained below 1.2 m/s to prevent cavitation. A bell-mouth inlet fitting reduces turbulence and pressure drop at the pump suction port.

Filtration represents another critical design element. The PVQ52 requires clean hydraulic fluid to maintain the tight clearances between vanes, rotor, and cam ring. A return line filter with a beta ratio of ß10 ≥ 100 is recommended, with a filter element condition indicator to alert maintenance personnel when replacement is needed. For systems operating in dusty environments or with high contamination generation rates, consider installing an additional pressure filter on the pump outlet to protect downstream components.

Thermal management should be addressed during system design. The PVQ52's efficiency characteristics result in heat generation proportional to operating pressure and flow rate. For continuous-duty applications above 150 bar, a heat exchanger may be required to maintain fluid temperature below 60°C. Reservoir sizing also affects thermal management - a general rule of thumb is to provide 3-5 minutes of dwell time at maximum pump flow to allow heat dissipation and air release.

The 45.500 kg weight of this pump requires adequate structural support in mobile equipment installations. Mounting bolts should be torqued to Rexroth specifications using grade 8.8 or higher fasteners. For installations subject to severe shock and vibration, consider using vibration isolation mounts between the pump mounting flange and the equipment frame.
