High-Performance Hydraulic Vickers VQ Series Vane Pump - Reliable China Suppliers & Factory for Engineering Equipment
Technical Features of Vickers VQ-Series Vane Pumps
1
To adopt balanced hydraulic for the structure of intra-vane and ten-Vane design, higher pressure, top to 21 MPa.
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, so that the life of pump will be longer.

Frequently Asked Questions (FAQ)
What is the maximum operating pressure of the Vickers VQ-Series vane pumps?
The maximum operating pressure of the VQ-Series vane pumps can reach up to 21 MPa, depending on the specific series and flow code configurations.
How does the floating structure of the side plate benefit the pump performance?
The floating structure allows for automatic compensation of end-face clearance. This ensures that the pump maintains high volumetric efficiency even when operating under high pressure.
What materials are used for the side plates of the VQ-Series pumps?
The side plates are constructed from dual-metal materials, which significantly improves seizure resistance and extends the overall service life of the pump.
What fluid media are compatible with the Vickers VQ-Series?
They are compatible with petroleum series oil and emulsification fluids. Additionally, the F3 designated models are suitable for water glycol-fluid and phosphate ester fluid applications.
What are the speed limitations for the VQ-Series vane pumps?
The minimum operating speed for all models is 600 r/min. The maximum speed ranges between 2200 r/min and 2700 r/min, depending on the specific pump series (20VQ, 25VQ, 35VQ, or 45VQ).
