Product Questions & Answers

Got a mini excavator and a crawler dozer both needing pump work this season. This the right series to be looking at for that kind of equipment?

Question by: Billy H on Oct 17, 2025, 9:44 PM

Both of those machines fall squarely in the application range for this pump. The X20 420 Series is specifically listed for mini excavators and crawler dozers, so you're not stretching the fit at all. It's an open circuit piston pump rated at 3.00 cubic inches per displacement (49cc), built for heavy-duty mobile hydraulic work. The high pressure and flow capacity it carries makes it a solid match for equipment that sees real load cycles day in and day out.

So, this thing will work alright on my backhoe? I'm always a little nervous buyin' stuff online.

Question by: Rod W on Feb 20, 2026, 3:49 PM

This Danfoss/Eaton open circuit piston pump is used in loader backhoes, among many other applications, so it should be a good fit. It's also used in agriculture tractors, mini excavators, and material handling equipment, so it's built for heavy-duty work.
