description

• Variable Volume Vane Pump

features

• Stable, 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.
• High-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
• 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 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.
