Frequently Asked Questions

What does the VG Series Model Designation mean?
The model designation details the specific configuration of the double pump. For example, in "VG11-63-40-R-E-W-A1": "VG11" represents the series, "63" and "40" specify the flow codes (ml/r) for the shaft end and cover end pumps respectively, "R" indicates clockwise rotation, "E" represents a straight key shaft, "W" denotes NBR sealing material, and "A1" is the design number.
How is the rotation direction determined for VG oil pumps?
The rotation direction is determined by viewing the pump from the shaft end. "R" stands for Right-hand (clockwise rotation), while "L" stands for Left-hand (counter-clockwise rotation).
What shaft types are available for the VG Series?
We offer two primary shaft options to suit different application requirements: "E" for a Straight Key Shaft, and "R" for an SAE Spline Shaft.
What sealing materials are used in these pumps?
Two standard sealing materials are available depending on your fluid and temperature demands: "W" (Buna NBR) and "V" (Viton FKM) for enhanced thermal and chemical resistance.
How do I choose the correct installation dimensions for VG11, VG21, and VG22?
Installation dimensions depend on the combination of the Front Pump and Rear Pump sizes. Refer to the respective installation dimension tables for VG11, VG21, or VG22, and match your front and rear pump displacement specifications to find the exact L1, L2, and L3 lengths.
