Vane Pump Nachi VDR13

Vane Pump Nachi VDR13 design Series Variable Volume Vane Pump 20 to 45 l/min, 6 MPa.

Features Vane Pump Nachi VDR13

1. Energy efficient, economical operation.
2. Built in high precision temperature compensation mechanism.
3. The ring is displaced by a spring, and a rise in pressure automatically moves it to the center to make the discharge rate zero.
4. Relief valve and unloading valve can be eliminated from the circuit.
5. 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.
6. New design for lower noise and improved durability.
