PVF Series Variable Vane Pump | PVF-12, PVV-15, PVF-20, PVF-30 | High Efficiency

PVF Series High-Precision Pressure Compensated Variable Vane Pumps

Product Overview: The PVF Series variable displacement vane pump is the cornerstone for high-performance industrial hydraulic systems prioritizing energy efficiency. Engineered as an advanced Pressure Compensated pump, it instantaneously senses system pressure changes and automatically adjusts displacement to provide “oil on demand.” This range features a complete spectrum of mainstream models, including PVF-12-35-10S, PVF-20-70-10, PVF-30-55-11S, PVF-15-55-10, and PVF-12-70-10. With precision-machined internal components, the PVF series drops to near-zero flow once the preset pressure is reached, drastically cutting wasted energy and suppressing oil temperature rise—making it the ideal choice for enhancing machining precision and equipment longevity.

Key Technical Advantages:

• Intelligent Energy Saving: Integrated pressure compensation valves automatically minimize flow during actuator standby or pressure-holding phases, reducing energy consumption by over 40% compared to fixed pumps.

• Ultra-Low Heat Generation: By significantly reducing overflow losses, it effectively inhibits hydraulic oil temperature rise, protecting seals and maintaining system viscosity stability.

• High-Sensitivity Response: Offers exceptional flow-to-pressure dynamic response, ensuring swift movements and precise positioning for machine tools during high-frequency cycles.

• Silent Bearing Support: Features a specially designed pressure-balanced structure and high-quality bearings, maintaining smooth operation and ultra-low decibel levels even at 70 Bar pressures.

• Target Applications: CNC lathes, vertical/horizontal machining centers, shoe-making machinery, precision grinders, automated production lines, and eco-friendly industrial Hydraulic Power Units (HPU).
