SVPF Series High-Performance Variable Displacement Vane Oil Pumps

Product Overview: The SVPF Series variable displacement vane oil pumps are the premier power source for modern precision hydraulic systems aiming for “Low Energy Consumption and Ultra-Quiet Operation.” As an advanced pressure-compensated pump, it automatically adjusts output flow based on system load demand. This range features core models including SVPF-20-55-20, SVPF-20-70-20, and the high-flow SVPF-40-70-20. Utilizing a precision pressure-compensated mechanism, the SVPF series de-strokes to near-zero displacement once the set pressure is reached (e.g., during machine clamping or pressure-holding), significantly saving energy while effectively controlling oil temperature rise.

Key Technical Advantages:

• Intelligent Energy Savings: Features automatic pressure compensation. During deadhead phases when actuators are idle, the pump reduces eccentricity to a minimum, cutting power consumption by 30% – 50% compared to fixed systems.

• Ultimate Silent Performance: Precision-ground vane assemblies and optimized suction port geometry ensure exceptionally low decibel levels across all pressure ranges, ideal for quiet workshop environments.

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

• Low Temperature Rise Stability: Precision internal clearance management minimizes heat generated by internal leakage, ensuring minimal oil temperature rise during prolonged pressure-holding cycles.

• Target Applications: CNC lathe clamping systems, precision grinding machines, specialized machine tools, woodworking machinery, and compact energy-saving industrial power units.
