Product Questions & Answers

Got a loader backhoe that needs a new pump and I keep seeing this 420 series pop up. Is it actually built for that kind of work or is it more of a specialty unit?

Question by: Cody B on Feb 15, 2026, 1:55 PM

Loader backhoes are right in the wheelhouse for this pump. The X20 420 series is an open circuit piston pump built specifically for mobile hydraulic applications, and loader backhoes are one of the primary uses it was engineered around. It also handles things like rough terrain forklifts, dump truck lifts, and crawler dozers, so it's well suited to the kind of hard-working equipment that sees real daily abuse. The high pressure and flow capacity backs that up for demanding cycles.

So, this is an open circuit pump, right? What does that mean for how it gets used?

Question by: Tammy P on Apr 1, 2026, 8:14 PM

Open circuit piston pumps like this Danfoss/Eaton model are generally used in systems where the fluid is drawn from a reservoir, pressurized by the pump, and then sent to perform work before returning to the reservoir. This makes it suitable for mobile equipment where a continuous loop isn't necessary.
