Nachi Vane Pump Nachi Vane Pump Manufacture

1. Energy saving, economical pump.

2. Built in high-precision pressure compensation structure.

3. The oil ring is in a biased state due to the spring force, and automatically moves to the center as the pressure increases, resulting in zero discharge.

4. The overflow valve and unloading valve in the circuit can be omitted.

5. The input that increases proportionally to the pressure can prevent an increase in oil temperature and has the characteristic of small volume.

6. The new design achieves low noise and durability. (There are many similarities with the Fujitsu UVN series vane pump):

1. Working environment: Avoid the impact of noise, pollution, and impact.

2. Check the steering, speed range, pressure, temperature, oil quality, and viscosity of the pump;

3. Check whether the suction conditions of the pump meet the usage requirements;

4. Filtering: Must meet the minimum pollution level requirements;

5. Check whether the type and torque of the transmission shaft meet the requirements of the working conditions;

6. Select appropriate couplings to minimize the radial load of the pump (caused by weight, different shaft deviations, etc.);
