VQ Series Single Pumps
Introduction
The high-pressure and high-performance Intra-vane pumps for mobile equipment.
Features:
- To adopt balanced hydraulic for the struction of Intra-vane and ten-Vane design, higher pressure, top to 21MPa.
- 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.
- The side plate is made of dual-metal material, it improved the seizure resistance, and so that the life of pump will be longer
