Product Questions & Answers

Will this Eaton-Danfoss pump hold up okay on a dump truck lift that gets used pretty hard, day in and day out?

Question by: Eddie R on Nov 7, 2025, 6:59 PM

For dump truck lifts and other demanding mobile hydraulic applications, this open circuit axial piston pump from the X20 420 Series is designed for reliable high-pressure performance across a range of heavy-duty equipment.

Got a mini excavator and a loader backhoe both sitting idle cause the pumps went out, this unit rated for either one of those machines?

Question by: Pete H on Nov 24, 2025, 9:33 PM

Both of those applications fall squarely in the intended use range for this pump. The X20 420 Series was built with loader backhoes and mini excavators specifically in mind, along with a pretty wide spread of other mobile equipment. At 3.80 CID (62 cc) displacement, it handles the kind of variable hydraulic demand those machines put on a system, and the fast response and recovery characteristics help when you're cycling between functions quickly on a loader or digging with an excavator.
