Nachi Pump VDR22 design series variable volume vane pump 30 l/min 14MPa, 40 l/min 7 MPa.
Features Nachi Pump VDR22
- Stable, highly efficient operation up to 14MPa
A biased piston that minimizes ring vibration and leak free pressure balance construction enables highly efficient high pressure operation, and very stable performance up to 14MPa. - High precision instantaneous response.
Response has been improved by a special bias piston mechanism. Prompt response at both ON-OFF and OFF-ON ensures instantaneous, stable, high precision operation. - Silent operation, even in the high pressure range
Quiet journal bearings, a bias piston that allows a 3-point support system, and new suction and discharge port shapes all contribute to minimize operation noise. Silent, vibration-free operation is ensured, even in the high pressure range. - Reduced power loss
A combination of NACHI-original mechanical innovations and precision machining create a pump that minimizes power loss, especially at full cutoff. - Solid construction stands up to harsh operating condtions
The tough and rugged construction of this pump is made possible by a long history of quality pump designs. This, in combination with specially selected materials and skilled workmanship, provides outstanding durability.
