Nachi VDR22 and VDR13 Series Variable Volume Vane Pump

‍The Nachi VDR series of vane pumps offer quick responsiveness and efficiency while operating at high pressures up to 14MPa. Nachi hydraulic components are known for precision construction, durability and ability to tolerate tough operating conditions. Minimal power loss and quiet operation with little vibration. Best uses include in industrial machines, machine tools and mobile hydraulics systems for vehicles.

VDR22 Design Series Variable Volume Vane Pump feature:

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 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.

VDR13 Design Series Variable Volume Vane Pump feature:

The new design number 13 was created by modifying some of the components of old design numbers 11 and 12, and the new design installation compatible with the old design.

Energy efficient, economical operation

Built-in high-precision temperature compensation mechanism

The ring is displaced by a spring, and a rise in pressure automatically moves it to the center to make the discharge rate zero.

Relief valve and unloading valve can be eliminated from the circuit.

It was possible to reduce the size of the unit because there was no increase of proportional input to pressure which prevented increases in the temperature of the fluid.
