Frequently Asked Questions (FAQ)

1. What does the model code structure of the VG series double pump represent?

The model code represents the configuration details. For example, in VG11D-63-40-R-E-W-A1: "VG11D" is the series; "-63" is the flow code of the shaft end pump; "-40" is the flow code of the cover end pump; "R" indicates the rotation direction (Right hand for clockwise); "E" represents the shaft type (Straight key shaft); "W" represents the sealing material (Buna NBR); and "A1" is the design number.

2. What shaft types and sealing materials are available for these double pumps?

You can choose between a Straight key shaft (E) and an SAE Spline shaft (R). For sealing materials, Buna NBR (W) and Viton FKM (V) are available to match different media and temperature requirements.

3. What is the maximum displacement combination for the VG series?

The maximum displacement combination can be extended up to 320CC, which offers ample selection flexibility for motor matching, driver selection, and system planning.

4. How does the coupling design of the front and rear pumps improve performance?

The front and rear oil pumps utilize a floating flower-splined coupling structure combined with a unique grease formula. This configuration ensures stable performance, low noise, and a prolonged operational life.

5. Is the oil port orientation flexible during installation?

Yes, the direction of both the oil outlet and the suction inlet of the VG series oil pumps is flexible, making it highly adaptable and easy to install in various system configurations.
