Question by: Wade M on Mar 2, 2026, 5:20 PM
We run a loader backhoe pretty hard out on job sites and been burnin through pumps faster than we'd like. This the 420 Series from Danfoss/Eaton with the 3.00 CID displacement?
Answer by: Customer Support on Mar 4, 2026, 7:14 AM
that's the one. Part number 421AK00223B, 3.00 cubic inch displacement which works out to 49 cc. It's built for exactly that kind of application too. Loader backhoes are right at the top of the list for what this pump was put together to handle, and the 420 Series is rated for high pressure and high flow, so it's not going to fold under a heavy workload the way a lesser pump might.
