Performance Features
-
High-Efficiency & Stable High-Pressure Operation: Equipped with innovative pressure control, pressure balance mechanisms, and an original 3-point ring support system, ensuring outstanding performance at high pressures up to 21 MPa (214 kgf/cm²), suitable for heavy-duty industrial scenarios.
-
Low Vibration & Noise: The 3-point support system for the control piston and bias piston enhances ring stability, minimizing vibration and enabling quiet operation—ideal for noise-sensitive working environments such as precision machining workshops.
-
High-Precision Response: An innovative ring stopper eliminates excessive ring displacement, ensuring high-precision operation during startup, shutdown, and load changes, effectively reducing hydraulic system errors.
-
Easy Maintenance: Pressure and discharge rate adjustment mechanisms are located on the same side of the pump, simplifying maintenance and reducing downtime, which helps improve production efficiency.
-
Energy-Saving & Durable: New mechanical innovations minimize power loss, especially at full cutoff, achieving high-efficiency operation and reducing energy consumption; the high-quality material and precision manufacturing extend the pump’s service life.
