Danfoss / Eaton-2.50 CID(41CC)420 Code B

Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton-2.50 CID(41CC)420 Code B is an open circuit piston pump built around the X20 420 Series platform. With a 2.50 cubic inch displacement (41 cc), it delivers high pressure and flow capacity suited to heavy-duty mobile equipment including loader backhoes, agriculture tractors, crawler dozers, mini excavators, and articulated haulers.

The 420 Series platform supports a broad range of working environments, from mining machinery and tunnel boring equipment to concrete and asphalt pavers, feller/bunchers, container handling equipment, and utility boom trucks. Advanced control options contribute to system efficiency, while the pump's response and recovery characteristics make it well suited to applications with variable or intermittent demand cycles. A product width of 5.75 inches is noted for installation reference.

Question by: Sheila T on Dec 23, 2025, 6:29 AM
Just wanna be sure, this'll work on my mini excavator?
Answer by: Customer Support on Dec 25, 2025, 6:49 AM
Designed for heavy-duty mobile equipment, this open circuit piston pump is used on mini excavators, among other applications.
Question by: Lee S on Mar 20, 2026, 6:44 PM
Got a mini excavator and a crawler dozer both running off the same machine setup, would this pump hold up across both those applications or is it more of a one-trick pony?
Answer by: Customer Support on Mar 22, 2026, 6:35 AM
Both of those fall squarely within what the X20 420 Series was built for. Mini excavators and crawler dozers are both listed application types for this pump, so you're not stretching it or asking it to do something outside its design range. The 2.50 cubic inch displacement gives you solid flow capacity, and the platform handles variable and intermittent demand well, which is pretty common when you're switching between implements or load cycles on that kind of equipment.
