Frequently Asked Questions

What does the VG series pump model designation stand for?

The model designation specifies the series (e.g., VG11, VG21, VG22), the flow codes for both the shaft end and cover end pumps (in ml/r), the rotation direction, the shaft type, the sealing material, and the design number.

What rotation directions are available for VG oil pumps?

Viewed from the shaft end of the pump, the rotation direction can be either R (Right hand for clockwise rotation) or L (Left hand for counter-clockwise rotation).

What sealing materials are used in VG series pumps?

Two standard sealing materials are available: W (Buna NBR) and V (Viton FKM), allowing for compatibility with different hydraulic fluids and operating temperatures.

What are the differences between E and R shaft types?

Type E refers to a straight key shaft, whereas Type R indicates an SAE spline shaft, providing flexible mounting options for various industrial drive systems.

How do I find the correct installation dimensions for a VG series pump?

Installation dimensions (L1, L2, L3) are determined by checking the front pump displacement size against the rear pump displacement size in the corresponding dimension tables (VG11, VG21, or VG22).
