VDR 22 DESIGN SERIES VARIABLE VOLUME VANE PUMP
 
 
Features Specifications qStable, highly efficient operation up to 14MPa A biased piston that minimizes ring vibration and leak-free pressure balance construction enables highly efficient highpressure operation, and very stable performance up to 14MPa. wHigh-precision instantaneous response Response has been improved by a special bias piston mechanism. Prompt response at both ON-OFF and OFFON ensures instantaneous, stable, high-precision operation. eSilent 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. rReduced power loss A combination of NACHI-original mechanical innovations and precision machining create a pump that minimizes power loss, especially at full cutoff. tSolid 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 durability
