Product Introduction
The High-pressure and high-performance Intra-vane pumps for Mobile Equipment or Industrial Machinery

Features

1. To adopt balanced hydraulic for the structure of Intra-vane and ten –Vane design, higher pressure, max to 210 Bar.

2. To adopt floating structure for side plate, it will do a compensation for end-face clearance by automatic, so that even the pump under high pressure it can maintain a high volumetric efficiency.

3. The side plate is made of dual-metal material, it improved the seizure resistance, and so that the life of pump will be longer.
