I'm looking for a pump for a loader backhoe, is this one suitable?

pump's got a 3.00 CID displacement and I keep seeing "420 Series" in the name -- what does that actually tell me about what I'm getting here?

Question by: Ralph D on May 21, 2025, 7:28 AM

The 420 Series designation is part of Danfoss/Eaton's X20 open circuit piston pump lineup, and that 3.00 cubic inch displacement (49cc) tells you the volume of fluid the pump moves per shaft revolution. Bigger displacement generally means more flow at a given RPM, which is why this unit gets used in high-demand mobile equipment like loader backhoes, crawler dozers, and mini excavators. The "Code B" in the part number refers to a specific configuration within the series. If you're matching it to an existing setup, the supplier part number is 421AK01769B and the product width runs 5.75 inches, so those are your hard reference points for fitment.
