Product Overview
The YUKEN SVPF-20-70-20 is a high-performance variable displacement hydraulic vane pump engineered by YUKEN, a globally recognized leader in precision fluid power technology. Operating on the proven balanced vane principle, this pump utilizes a hydraulically balanced rotor and precision-ground vanes that track against a movable cam ring to vary the displacement and maintain constant pressure or flow as demanded by the system. The SVPF series is specifically designed for industrial circuits requiring smooth, low-pulsation output with the ability to automatically adjust delivery to match actuator demand, thereby reducing heat generation and power consumption. With a nominal displacement of 70 cm³/rev and a 20-series pressure-compensated control configuration, the SVPF-20-70-20 serves as a reliable, energy-efficient power source for continuous-duty hydraulic systems in demanding manufacturing environments.

Engineering Features & Advantages
- Precision Performance: The hydraulically balanced rotor and precision-ground vanes deliver exceptionally smooth, low-pulsation flow, minimizing noise and vibration while extending the service life of downstream valves and actuators.
- Variable Displacement Efficiency: The 20-series pressure compensator automatically reduces displacement as system pressure approaches the set point, cutting power consumption and heat generation during holding or idle phases.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust cam ring and durable cartridge design that withstands high duty cycles and contaminated environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original YUKEN SVPF series mounting footprints, shaft configurations, and port locations for drop-in OEM replacement.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original YUKEN OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
