Features & Benefits

VG OIL PUMP
The front and rear oil pumps adopt floating flower-splined coupling structure, with a unique grease formula to ensure stable performance, long life and low noise of the oil pump.
The maximum displacement can be extended to 320CC, which provides enough choice space for motor and driver selection and model selection.
The direction of oil outlet and suction outlet of oil pump is flexible and easy to install.
Any displacement combination, to meet the needs of different working conditions.

Frequently Asked Questions

What do the different codes in the VG series model representation mean?
The model representation code (e.g., VG11D-63-40-R-E-W-A1) specifies the exact configuration of the pump: "VG11D" stands for the series, "63" is the displacement at the shaft end, "40" is the displacement at the cover end, "R" indicates the clockwise rotation direction (viewed from the shaft end), "E" represents a straight key shaft, "W" indicates NBR sealing material, and "A1" is the design number.
What shaft types and sealing materials are available for the VG series double pumps?
The VG series offers two shaft types: Straight key shaft (E) and SAE Spline shaft (R). For sealing materials, you can choose between NBR (W, Buna) and FKM (V, Viton) depending on your application requirements.
What are the benefits of the floating flower-splined coupling structure?
The front and rear oil pumps utilize a floating flower-splined coupling structure paired with a unique grease formula. This configuration ensures stable performance, significantly extends the service life of the pump, and reduces operational noise.
What is the maximum displacement capacity of these double pumps?
The maximum displacement of the VG series double pumps can be extended up to 320CC. This broad range provides sufficient flexibility for motor and driver selection as well as model customization.
Can the direction of the oil inlet and outlet ports be adjusted?
Yes, the installation directions for both the oil outlet and the suction inlet of the pump are flexible. This adaptability makes them easy to install and align with various system layouts.
