VDC series vane pump characteristics:

1. High-efficient and stable high-pressure operation: with unique pressure control structure and pressure balance structure, independent oil ring 3-point support mode effectively improves high-pressure operation performance. The running pressure is as high as 14MPa, which is efficient and stable.

2. Vibration, low noise and quiet: The stability of the oil ring is effectively improved by adopting various structures of anti-vibration and noise. The oil ring is supported by two pistons, control piston and offset piston in an independent three-point way, which has the characteristics of small vibration, balanced operation and low noise.

3. Fast response and high-precision action: Through the new block structure, the oil ring displacement is solved, and the responsiveness is improved. High-precision action can be obtained at start, stop and load change.

4. Accurate characteristics, stable discharge: pressure control structure in the form of pressure compensator can achieve high pressure performance, high and stable rated discharge.

5. Efficient operation to reduce power loss: According to various new structures, power loss can be further reduced, especially when the power loss is completely stopped.

6. Maintenance and operation are simple: Because the pressure adjustment structure and discharge adjustment structure are installed side by side on the same side of the pump, the maintenance and operation are simpler.
