Product Questions & Answers (1)

Question by: Ronnie H on Nov 1, 2025, 7:08 PM

trying to figure out if this pump'll work as a drop-in swap on my machine, it's running a 25VQ setup now and I need to match the shaft and mounting. what does this one use?

Answer by: Customer Support on Nov 3, 2025, 6:41 AM

For mounting, this pump uses a 2-bolt SAE B flange, which is standard for the 25VQ series. The shaft is a 7/8 inch straight keyed, and the port configuration is SAE 4-bolt flange with a 1-1/2 inch inlet and a 1 inch outlet. The inlet on this unit sits 90 degrees counterclockwise from the outlet, so as long as your current setup matches that orientation and runs clockwise rotation, the physical fit should line up without modification.
