NACHI PUMP VDC SERIES High Pressure Type Variable Volume Vane Pump 30 to120 l/min, 14 MPa.

Features Nachi Pump VDC Series
- Highly efficient and stable high pressure operation
Innovative pressure control and pressure balance mechanism combine with an original 3 point ring support system dramatically improves high pressure operation. The result is outstanding performance at high pressure up to 14MPa - Low vibration and noise
A number of innovative new mechanism are adopted to minimize vibration and noise. In particular, a 3-point support system is used for the control piston and bias piston to increase ring stability. This minimizes ring vibration and delivers quiet operation. - Outstanding response, high precision operation
An innovative new ring stopper eliminates excessive ring displacement and improves response. The result is high precision operation at all times including during starts, stops, and load changes. - Precise characteristics for a stable discharge rate
A revolutionary new pressure compensator type pressure control mechanism ensures a highly stable fixed discharge rate, even in the high pressure range. - High efficiency operation with minimal power loss
New mechanical innovations minimize power loss, especially at full cutoff. - Simplified maintenance and handling
Pressure adjusting and discharge rate adjusting mechanisms are located on the same side of the pump for simplified maintenance and handling.
