Vane Pump Nachi VDR22 Design series variable volume vane pump 30L/min 14MPa 40L/min 7MPa. High efficient, high precision, silent operation, reduce power loss and solid construction stands up harsh operating condition.
Features :
- 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.
- 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.
- 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 conditions,
- The tough and rugged construction of this pump is made possible by a long history of quality pump designs.
