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

Features Vane Pump Nachi VDR13
- 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.
- New design for lower noise and improved durability.
