Performance Features of Nachi VDC-2A-1A5 & VDC-2B-1A5
-
High-Efficiency & Stable High-Pressure Operation: Equipped with innovative pressure control, pressure balance mechanisms, and an original 3-point ring support system, the pumps deliver outstanding performance at high pressures up to 14 MPa (2000 psi), minimizing power loss and ensuring stable operation[superscript:3].
-
Low Vibration & Noise: The 3-point support system for the control piston and bias piston enhances ring stability, effectively reducing ring vibration and achieving quiet operation, which is suitable for noise-sensitive working environments[superscript:2].
-
High Precision & Quick Response: An innovative ring stopper eliminates excessive ring displacement, improving response speed and ensuring high-precision operation during startup, shutdown, and load changes[superscript:3].
-
Stable Discharge Rate: Adopting a revolutionary pressure compensator-type pressure control mechanism, the pumps maintain a highly stable fixed discharge rate even in the high-pressure range[superscript:2].
-
Easy Maintenance: Pressure adjusting and discharge rate adjusting mechanisms are located on the same side of the pump, simplifying maintenance and handling procedures[superscript:3].
