Product Questions & Answers

Got a loader backhoe that needs a new pump and I keep seeing this 420 series come up. Is that a application it's actually built for or just something folks slap on and hope works?

Question by: Norm M on Dec 23, 2025, 5:20 PM

Loader backhoes are one of the core applications this pump was engineered around, so you're not guessing on that one. The X20 series in the 420 line covers a broad range of mobile equipment, and loader backhoes sit right at the top of that list alongside crawlers, mini excavators, and articulated haulers. The 3.80 CID displacement with high pressure and flow capacity is sized to handle the kind of continuous demand that equipment puts on a hydraulic system.

What kind of machinery does this Eaton piston pump usually go on?

Question by: Donna R on Apr 21, 2025, 4:06 PM

You'll find this Danfoss/Eaton open circuit piston pump used in a pretty wide range of equipment. Think loader backhoes, ag tractors, mini excavators, even stuff like mining machinery and concrete pavers. It's a common choice for mobile hydraulic applications.
