SVPF Series Variable Vane Pump | SVPF-20-70-20, SVPF-12/20-55 | Pressure Compensated

SVPF Series High-Efficiency Variable Displacement Vane Pumps

Product Overview: The SVPF Series variable displacement vane pump is the definitive power source for achieving energy efficiency and precision control in modern industrial hydraulics. Engineered with an integrated Pressure Compensated mechanism, this high-efficiency pump automatically adjusts its flow output based on the real-time pressure demands of the system. This range features core models including single pumps SVPF-20-70-20, SVPF-20-55-20, and versatile double pump configurations like SVPF-20/12-55/70/35-B-20. By automatically reducing displacement to a minimum once the preset pressure is reached, the SVPF series eliminates overflow loss and suppresses oil temperature rise—making it the premier choice for enhancing the stability of precision machine tools.

Key Technical Advantages:

• Automatic Displacement & Energy Saving: The high-precision compensation structure ensures minimal flow during standby or pressure-holding states, boosting system energy efficiency by over 30%.

• Ultra-Quiet Operation: Features an optimized slider-balance design that maintains a remarkably quiet performance even under frequent pressure fluctuations.

• Rapid Dynamic Response: Provides exceptional flow-to-pressure switching characteristics, ensuring swift actuator movements and highly accurate positioning.

• Compact & Easy Integration: Its space-saving design supports both B (Single) and Double-pump configurations, catering to everything from small grinders to complex automated lines.

• Target Applications: CNC machining centers, automated grinding machines, shoe-making machinery, woodworking equipment, and eco-friendly industrial Hydraulic Power Units (HPU).
