Question by: Ralph R on Dec 13, 2025, 7:26 PM
What kinda machines can you put this hydraulic pump on? I got an old tractor I'm fixin' up.
Answer by: Customer Support on Dec 15, 2025, 8:58 AM
This Danfoss/Eaton open circuit piston pump is well-suited for equipment like agriculture tractors, loader backhoes, and even some of the bigger stuff like crawler dozers. It's also used on machinery such as dump truck lifts and container handlers.
Question by: Denise W on Nov 27, 2025, 6:38 AM
What kind of equipment is this pump actually built for? Got a loader backhoe and a couple crawlers sitting in the yard and trying to figure out if it fits the bill.
Answer by: Customer Support on Nov 29, 2025, 8:41 AM
Loader backhoes and crawler dozers are both right in the wheelhouse for this pump. The 420 Series covers a pretty wide range of mobile equipment, including agriculture tractors, mini excavators, dump truck lifts, and container handling machinery. It runs on an open circuit piston design, handles high-pressure and high-flow demands, and has a 3.80 CID (62cc) displacement. For the kind of work those machines typically see, this platform was put together with exactly that in mind.
