Serial Advantage

  • High pressure and ultra-high pressure open hydraulic system.

  • In addition to conventional pressure cutoff, load sensitivity, and constant power, it also has electro-hydraulic proportional and electro-hydraulic servo control modes.

  • External or internal digital electro-hydraulic control amplifier.

  • Integrated closed-loop control of flow rate, pressure, and power.

  • Equipped with built-in variable speed adjustment function, which matches the variable speed motor to form a variable speed energy-saving system.

  • Equipped with synchronous and volumetric efficiency compensation functions.

  • Low noise, long lifespan, strong self-priming ability.

  • Optional negative swing angle pressure relief mode.
