Nachi are a world-class manufacturer of pumps, valves, flow controls, hydraulic power units and other products. Known not only for product excellence but for our competitive pricing and product availability.
The PVS Series from Nachi offers a displacement range from 8 - 45cc/rev and continuous pressure of 210 bar.
The NACHI-proprietary semi-circular barrel swash plate that receives pressure on its surface always ensures a stable discharge volume. This eliminates excess discharge volume and enables the effective use of power corresponding to the load cycle. This "energy-saving type" conserves energy, reduces power loss, and helps to reduce hydraulic costs.
Proprietary low-noise mechanisms are incorporated on the shoe, swash plate, valve plate, and other locations to ensure silent operation. A semi-circular barrel swash plate stabilizes operation characteristics to ensure silent operation.
The new mechanisms reduces vibration and noise levels. Of particular note is the unique and exclusive threepoint support system which uses, a regulating piston and a bias piston to eliminate vibration. The mechanism, together with improvements to the shape of the inlet and outlet ports and high performance journal bearings, has reduced the noise level during operation.
Efficiency has been improved with the new mechanisms and Nachi's high precision machining technology. Power loss has been reduced, especially during dead-heading.
Maintenance is easier due to the positioning of the pressure adjusting mechanism and the volume adjusting mechanism on the same side of the pump.
