Key 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 excellent performance at high pressures up to 14 MPa.
-
Low Vibration & Noise: Adopts advanced mechanisms, including 3-point support for control piston and bias piston, minimizing ring vibration and achieving quiet operation适合 industrial environments requiring low noise levels.
-
Precise & Stable Discharge Rate: A revolutionary pressure compensator-type pressure control mechanism maintains a highly stable fixed discharge rate even in the high-pressure range.
-
High Efficiency with Minimal Power Loss: New mechanical innovations reduce power loss, especially during full cutoff, improving energy efficiency and reducing operating costs.
-
Easy Maintenance & Handling: Pressure adjusting and discharge rate adjusting mechanisms are located on the same side of the pump, simplifying maintenance and daily operation.
-
Outstanding Response: An innovative ring stopper eliminates excessive ring displacement, ensuring high-precision operation during starts, stops, and load changes.
Application Scope
Notes
-
The operating fluid must meet ISO VG 32-68 standards with a viscosity index of 90 or higher to ensure pump performance and service life.
-
Do not exceed the maximum revolution speed (1800 rpm) or allowable peak pressure (14 MPa) to avoid damage to the pump.
-
Regular maintenance is recommended to check the pump’s pressure, discharge rate, and fluid quality, ensuring stable operation.
-
