High-Pressure Vickers VQ Series Vane Pumps from China Suppliers - Reliable Performance from Leading Factory
Technical Features of Vickers VQ-Series Vane Pumps
1
To adopt balanced hydraulic for the struction 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. and so that the life of pump will be longer.

Frequently Asked Questions (FAQ)
Q: What is the maximum operating pressure of the Vickers VQ-Series Vane Pumps?
The VQ-Series vane pumps can operate at pressures up to 21 MPa for the 20VQ, 25VQ, and 35VQ series, and up to 17.5 MPa for the 45VQ series.
Q: How does the VQ-Series maintain high volumetric efficiency under high pressure?
The pumps employ a floating structure for the side plate, which automatically compensates for end-face clearance, ensuring high efficiency even under high-pressure conditions.
Q: What material is used for the side plate, and what are its benefits?
The side plate is manufactured from dual-metal material, which significantly improves seizure resistance and extends the overall service life of the pump.
Q: What fluid types are compatible with the VQ-Series pumps?
They are compatible with Petroleum series oil, Emulsification fluid, Water glycol-fluid, and Phosphate ester fluid (indicated by the F3 prefix).
Q: What rotation options are available for these vane pumps?
They support both right-hand (clockwise, marked as R) and left-hand (counter-clockwise, marked as L) rotations when viewed from the shaft end of the pump.
Q: What is the minimum and maximum speed range for the VQ-Series?
The minimum operating speed for all series (20VQ to 45VQ) is 600 r/min, while the maximum speed ranges between 2200 r/min and 2700 r/min depending on the specific model and flow code.
