Pump Cylinder

Pump Cylinder

Usage

Press, Assembly, Press Fitting , Trimming, Banding, Bonding, and Spot Welding

Characteristics

Developed a hydraulic cylinder equipped with booster pump all-in-one, which advances at a high speed when low load, and advances with double action booster pump when high load. Additionally, when double action booster pump is spinning, the surging of pressure is minimized with built-in accumulator
