Danfoss / Eaton-3.80 CID(62CC)420 Code B

Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton-3.80 CID(62CC)420 Code B is an open circuit piston pump engineered to deliver high pressure and flow capacity across a wide range of heavy-duty equipment. With a displacement of 3.80 CID (62cc), this 420 Series unit suits systems where consistent performance and rapid response are critical.

Compatible equipment includes loader backhoes, agriculture tractors, crawler dozers, mini excavators, concrete and asphalt pavers, feller/bunchers, articulate haulers, vibratory cable plows, container handling equipment, and mining and tunnel boring machinery, among others. Advanced control options support greater efficiency in applications such as dump truck lifts, railroad equipment, utility boom trucks, and rough terrain forklifts. Response and recovery characteristics make this pump a practical fit for mobile equipment subject to variable load demands.

Question by: Norm A on Feb 8, 2026, 9:33 PM
Got a mini excavator and a crawler dozer both running open circuit systems, this 420 Series pump rated to handle that kind of workload across different machines?
Answer by: Customer Support on Feb 10, 2026, 6:12 PM
Both of those are squarely in the wheelhouse for this pump. Mini excavators and crawler dozers are among the equipment types this unit was built around, so running it in either open circuit setup is a solid fit. The 3.80 CID displacement and high pressure and flow capacity give it enough muscle for the variable load demands those machines throw at it. Swapping it between applications in your fleet isn't a stretch at all given how broadly this series was spec'd out.
