Product Questions & Answers

Got a mini excavator that's been burning through pumps and I need something built for that kind of work. This 420 Series unit rated at 3.00 CID, that displacement figure, is that per shaft revolution?

Question by: Wade G on Sep 20, 2025, 9:09 PM

Yes, 3.00 cubic inches per revolution is the displacement on this pump, which works out to 49cc. For a mini excavator running variable duty cycles, the 420 Series is a reasonable fit. It's listed specifically for that application, along with crawler dozers and loader backhoes that see similar stop-and-go hydraulic demand. The open circuit piston design handles those frequent load changes without the sluggish response you get from some lower-tier units.
