Nachi PVD Hydraulic Piston Pump

Nachi PVD Hydraulic Piston Pump is an innovative pump that was designed for use on small construction machinery such as mini excavators. The primary application of this pump is the delivery of two identical hydraulic flow outlets from one single unit. This would help ensure that the left and right travel lines get equal oil flow, thus making straight movement possible during travel.

In contrast to the traditional pump that only produces a single output, the PVD series contains both pumps in one single body. This means that the manufacturer can minimize the number of hydraulic parts used for producing pumps. Furthermore, the compact nature of the body ensures that the pump can fit into small engine compartments.

Nachi PVD range is based on the variable displacement piston pump. In its functioning, the revolving assembly causes a number of pistons to work, sucking hydraulic fluid into the pump and then pumping it out at high pressure. The displacement device varies the piston stroke depending on operational needs. As a consequence, the output of the pump can be varied.

One of the main features of Nachi PVD Pump is that it is made in the form of a dual equal-flow design. The output on both sides is balanced such that it is consistent. It becomes very critical in the case of excavators since an uneven amount of oil discharged through both track motors will make the machine move out of the straight path.

The Nachi company provides the PVD models with constant horsepower control. It is responsible for controlling the displacement of the pump in respect to hydraulic pressure, thus ensuring that the pump can effectively utilize the power of the engine.
