Frequently Asked Questions

Q: What models are included in the VG series double pump line?

The VG series consists of the VG10D, VG11D, VG21D, and VG22D double pump models, designed to handle varying displacement combinations and working conditions.

Q: What coupling structure is used in these pumps, and what are its benefits?

They utilize a floating flower-splined coupling structure combined with a unique grease formula. This design ensures stable performance, low operating noise, and an extended service life.

Q: What options are available for shaft types and sealing materials?

The pumps offer Straight Key Shafts (E) and SAE Spline Shafts (R). For sealing, you can choose between Buna NBR (W) and Viton FKM (V) depending on your application needs.

Q: Can the rotation direction of the VG series pumps be customized?

Yes, rotation directions viewed from the shaft end of the pump can be configured for clockwise (R - Right hand) or counter-clockwise (L - Left hand) operation.

Q: What is the maximum displacement available for the VG series?

The maximum displacement of the VG series double pump can be extended up to 320CC, providing substantial flexibility for motor and driver pairing.
