Frequently Asked Questions

What does the model designation VG11-63-40-R-E-W-A1 represent?

This model designation represents a VG series double pump (VG11) with a shaft end pump flow of 63 ml/r, cover end pump flow of 40 ml/r, clockwise rotation direction (R), straight key shaft type (E), Buna NBR sealing material (W), and design number A1.

What shaft type options are available for the VG series oil pumps?

The VG series oil pumps can be configured with two shaft types: E (Straight key shaft) or R (SAE Spline shaft).

Which sealing materials are offered for the VG pumps?

Depending on your application environment and medium, you can select sealing materials of either W ((Buna) NBR) or V ((Viton) FKM).

How do I determine the rotation direction of the pump?

The rotation direction is determined by viewing the pump from its shaft end. "R" stands for Right hand (clockwise rotation), and "L" stands for Left hand (counter-clockwise rotation).

What is the difference between VG11, VG21, and VG22 installation dimensions?

The difference lies in the combination of front and rear pump sizes. VG11 pairs smaller front and rear pumps (flows 25-63), VG21 pairs larger front pumps (80-160) with smaller rear pumps (25-63), and VG22 pairs larger front pumps (80-160) with larger rear pumps (80-160). Specific lengths (L1, L2, L3) for each combination are detailed in their respective dimension tables.
