PVR50 Series Variable Vane Pump | PVR50-F-F-39, 56, 45 | Pressure Compensated

PVR50 Series High-Performance Variable Displacement Vane Pumps

Product Overview: The PVR50 Series variable displacement vane pump is the definitive solution for high-efficiency power and precise pressure control in industrial hydraulic systems. Engineered with a built-in Pressure Compensated mechanism, it instantaneously adjusts flow output based on real-time load demand. This range features premium specifications including PVR50-F-F-39-RAA-3180, PVR50-F-F-45-RAA-3180, and the high-flow PVR50-F-F-56-RAA-3280. Utilizing superior cutoff characteristics, the pump automatically minimizes displacement once the preset pressure is reached, significantly lowering energy consumption and inhibiting system heat—making it the ideal power source for modern automated machinery.

Key Technical Advantages:

• Automatic Pressure Compensation: Equipped with a highly sensitive internal regulator. When the system reaches the preset pressure limit, the pump automatically reduces displacement to minimum flow, eliminating wasted overflow and reducing electrical costs.

• Ultimate Silent Operation: Advanced stator geometry and precision-ground vane construction ensure exceptionally low decibel levels even under high-pressure holding states, enhancing the workshop environment.

• Rapid Dynamic Response: Provides millisecond-level flow switching response, ensuring smooth actuator movement and precise positioning for high-frequency automated cycles.

• Low Heat Generation & Long Life: By reducing thermal buildup from excess circulation, it effectively controls oil temperature rise, extending the service life of seals and hydraulic fluids.

• Target Applications: CNC cutting machines, specialized grinders, small presses, spindle lubrication systems, woodworking machinery, and energy-saving industrial Hydraulic Power Units (HPU).
