Product Questions & Answers

got a 45VQ pump that finally gave out on us, been running it on a wheel loader for a few years now. this the same series that handles high-pressure work? want to make sure i'm not stepping down in performance before i order
Question by: Billy H on May 9, 2025, 7:38 AM
Same series, yes. The 45VQ runs up to 2500 PSI and is rated for high-pressure, high-speed applications, so if your previous unit was holding up on a wheel loader, this one is built for that same kind of work. Rated flow on this particular pump comes in at 77.14 GPM at up to 2200 RPM, which puts it squarely in heavy-duty territory for mobile equipment like that.

Reckon this’ll bolt right up to a standard SAE C flange? Got one of them old pumps going bad on my log splitter.
Question by: Bobby S on Nov 27, 2025, 8:25 PM
it’s got a 2-Bolt SAE C Mounting Flange. Should be a direct fit if your old pump uses that same flange.
