VQ Series Pump
The high-pressure and high-performance Intra-vane pumps for Mobile Equipment.
Features:
1. To adopt balanced hydraulic for the structure of Intra-vane and ten-Vane design, higher pressure, top to 21MPa.
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 proved the seizure resistance, and so that the life of pump will be longer.
