SVPDF & SVPF Series Variable Vane Pump | SVPDF-3035-3035, SVPF-20-55 | Pressure Compensated

SVPDF & SVPF Series High-Performance Variable Displacement Vane Pumps

Product Overview: The SVPDF and SVPF Series represent the core power solutions for intelligent energy-saving and multi-circuit control in hydraulic systems. While SVPF is a classic single variable pump renowned for its high response speed, SVPDF is a Double Variable Pump integrating two independent cartridges within a single housing. This page highlights premium models: the double pump SVPDF-3035-3035-20 and the single pump SVPF-20-55-20. Featuring precise Pressure Compensation, these pumps automatically transition to a low-flow standby state upon reaching preset pressure, drastically minimizing overflow losses and system heat.

Key Technical Advantages:

• Independent Dual-Circuit Regulation (SVPDF): The SVPDF series allows independent pressure and flow settings for both cartridges, enabling a “one pump, two circuits” configuration. One circuit can handle high-pressure clamping while the other powers auxiliary motions independently.

• Ultra-Fast Compensation Response: The highly sensitive regulation mechanism provides millisecond-level displacement adjustments based on load demand, ensuring stable system pressure and precise execution.

• Ultimate Silent Operation: Utilizing optimized vane geometry and precision-ground rotors, the pumps maintain exceptionally low decibel levels even in pressure-holding states.

• Superior Energy Efficiency: Eliminates heat losses found in fixed-displacement systems using relief valves, resulting in minimal oil temperature rise and extended service life for seals and hydraulic fluids.

• Target Applications: CNC machine clamping, automated footwear machinery, woodworking equipment, multi-station modular machines, and energy-saving hydraulic power units (HPU).
