VPKC Series High-Performance Variable Displacement Vane Oil Pumps

Product Overview: The VPKC Series variable displacement vane pumps are the premier choice for achieving “Silence and Energy Efficiency” in industrial hydraulic systems. As a precision pressure-compensated pump, it automatically adjusts output flow based on system load demand. This range features core models including VPKC-F12-A4-02-1, VPKC-F15-A4, VPKC-F20-A4-01/02, and the high-flow VPKC-F40-A4-D. Utilizing unique silencing grooves and side-plate pressure compensation technology, the VPKC series de-strokes to near-zero displacement once the set pressure is reached—drastically saving energy while effectively controlling oil temperature rise.

Key Technical Advantages:

• Automatic Pressure Compensation: The variable mechanism reacts instantaneously to load changes. During pressure-holding phases (deadhead), the pump operates at minimum power, saving 30% – 50% energy compared to fixed systems.

• Ultimate Silent Performance: Precision-ground vanes and cam ring profiles, combined with optimized suction port geometry, ensure operational noise remains at exceptionally low decibel levels even at its rated 7 MPa pressure.

• Low Temperature Rise Stability: Precision internal clearance management minimizes internal leakage and heat. This ensures minimal oil temperature rise during prolonged pressure-holding cycles, protecting the life of hydraulic seals and valves.

• Rapid Dynamic Response: The sensitive variable mechanism reacts instantaneously to actuator movements (e.g., cylinders or clamps), ensuring consistent cycle times and stability for precision CNC equipment.

• Target Applications: CNC lathe clamping systems, precision grinding machines, automated machining centers, woodworking machinery, and energy-saving hydraulic power units.
