Product Questions & Answers

got a Vickers 35VQ21A-11B20 on the machine now. is this the same pump and rotation, or am i gonna get burned on the shaft and ports
Question by: Ricky M on Oct 22, 2025, 1:31 PM
Match-up points on this one are the model number 35VQ21A-11B20, clockwise rotation, and the 14 tooth SAE C splined shaft. Porting is SAE 4-bolt flange with a 2 inch inlet and 1-1/4 inch outlet, and the mounting is a 2-bolt SAE C flange, so those are the key fit items to line up.

What kind of mounting does this pump use?
Question by: Donna R on Feb 16, 2026, 5:53 PM
This vane pump uses a 2-bolt SAE C mounting flange, so it should be pretty standard for a lot of setups.
Answer by: Customer Support on Feb 17, 2026, 7:11 PM
does this pump work on a 14-tooth splined shaft setup or do I need an adapter of some kind
Question by: Harvey R on Apr 20, 2025, 6:33 AM
Straight fit, no adapter needed. The 35VQ21A comes with a 14-tooth SAE C splined shaft, so if your drive already matches that spec, you're ready to bolt up and go. Just confirm your coupling matches SAE C before ordering.
