What kind of machinery is this pump good for?
Question by: Marvin T on May 1, 2025, 2:02 PM
This 25VQ series vane pump works well in heavy machinery like dump trucks and wheel loaders, along with oil and gas applications and metal cutting. It's also used in plastic injection molding equipment.
Answer by: Customer Support on May 3, 2025, 1:15 PM
Got a dump truck running a 25VQ pump now and the shaft wore out on me. This one's got the 13 tooth SAE B splined shaft, right? Just want to make sure it's a straight swap before I pull the trigger.
Question by: Ross B on Jan 26, 2026, 6:34 PM
Yeah, the shaft on this one is a 13 tooth SAE B splined configuration, so if your current pump uses that same shaft spec, you're looking at a direct match on that end. The mounting is a 2-bolt SAE B flange, and the ports are SAE 4-bolt flange style with a 1-1/2 inch inlet and a 1 inch outlet. Worth confirming those port sizes line up with your existing hydraulic connections before ordering, but the shaft itself checks out for what you're describing.
