Vane Pump Nachi VDR22 design series variable volume vane pump 30 l/min 14 Mpa, 40 l/min 7 Mpa. High efficient, high precision, silent operation, reduce power loss, and solid construction stands up to harsh operating conditions.
Features Vane Pump Nachi 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 14 Mpa - 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. - Reduce power loss
A combination of NACHI-original mechanical innovations and precision machining create a pump that minimizes power loss, especially at full cut – off - Solid construction stands up to harsh operating conditions
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 dirability.
