Question by: Cody H on Jul 3, 2025, 2:56 PM
need to swap out a pump, is this one the 25VQ21A-11D20 with the 13 tooth SAE B spline and CW rotation?
Answer by: Customer Support on Jul 4, 2025, 6:15 PM
Match-up wise, it lines up with model number 25VQ21A-11D20, a 25VQ series single vane pump with a 21 ring size and a 13 tooth SAE B splined shaft. It is also a clockwise rotation unit, with Buna-N seals.
