Product Questions & Answers

Got a loader backhoe that's been running a worn-out pump for two seasons now. This the kind of unit that'd hold up to that kind of daily grind?

Question by: Bonnie R on Dec 18, 2025, 6:08 PM

Loader backhoes are actually one of the primary applications this pump was built around. It's an open circuit piston pump rated for high pressure and high flow, so it's got the muscle for the kind of continuous, load-heavy work that chews through lesser units. The 420 Series from Danfoss/Eaton has a reputation for durability in exactly that kind of environment, and the advanced control options help keep the system running efficiently even when demand spikes.

I’m looking for a pump to use on some heavy equipment that sees rough duty. Would this Eaton/Danfoss unit be suitable for something like that?

Question by: Rhonda J on Feb 28, 2026, 9:32 PM

Designed for heavy-duty use, this open circuit piston pump excels in demanding environments. Its applications include mining machinery, agricultural tractors, and even rough terrain forklifts, so it should stand up to the job.
