Frequently Asked Questions (FAQ)
What does the model code "VG11D-63-40-R-E-W-A1" represent?
It represents a VG series double pump with a VG11D pump body, a 63 ml/r flow code for the shaft end pump, a 40 ml/r flow code for the cover end pump, clockwise rotation (viewed from the shaft end), a straight key shaft, NBR (Buna) sealing material, and design number A1.
What shaft and sealing options are available for the VG series?
For the shaft type, you can choose between a Straight Key Shaft (Code E) and an SAE Spline Shaft (Code R). For the sealing material, options include NBR (Buna, Code W) and FKM (Viton, Code V).
How is the rotation direction determined for these pumps?
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 are the benefits of the floating spline coupling structure?
The floating flower-splined coupling structure, combined with a unique grease formula, ensures stable performance, low operational noise, and a significantly extended service life for both the front and rear oil pumps.
Can the inlet and outlet port directions be customized during installation?
Yes. The direction of the oil outlet and suction inlet of the VG series oil pump is designed to be highly flexible, making it easy to configure and install according to various system requirements.
What is the maximum displacement capacity for the VG series double pumps?
The maximum displacement of the VG series can be extended up to 320CC. This wide range offers sufficient selection space when matching the pump with different motors and drivers.
