valve plate hydraulic pump factory

Hymon Hydraulics provide Piston Plunger Pump Parts Valve Plate for Rexroth A4VTG90 . We can make varies of hydraulic pumps parts with factory direct prices and have state of the art machining testing facilities to assist clients with their projects.

As the contact pressure is increased to 3 MPa, severe wear occurs on the upper sample (Figure 15(b)), and several pieces of bronze are torn away from its surface. For the lower sample shown in Figure 15(d), some bronze particles adhere to its surface, and its surface is severely oxidized by the friction heating. The results indicate that the valve plate/cylinder block friction pairs cannot reach the specified life at the contact pressure of 3 MPa.

Along with constantly improving performance, industrial machines continue to become increasingly sophisticated. Hydraulic equipment has to meet the challenge of diversifying needs.

You may already appreciate the Nachi-Fujikoshi reputation for compact equipment that delivers energy efficiency, safety, and high performance. Our equipment is also constantly refined by our quest for ultimate hydraulics that combine great power with flexible motion control.
