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 built around the 420 Series platform. With a displacement of 3.80 CID (62cc), it delivers high pressure and flow capacity suited to equipment that requires reliable hydraulic output under variable load conditions.

This pump is well-suited to a broad range of mobile machinery, including loader backhoes, agriculture tractors, crawler dozers, mini excavators, articulated haulers, vibratory cable plows, and concrete and asphalt pavers. It also sees use in container handling equipment, railroad machinery, utility boom trucks, and tunnel boring applications. Advanced control options support efficient power management across these varied duty cycles, and the pump's fast response and recovery characteristics make it practical for equipment where hydraulic demand changes frequently.

Reckon this pump'd hold up okay on a mini excavator where things get kinda dusty?

Designed for mobile hydraulic applications, this pump from the 420 Series is built to handle variable load conditions, making it suitable for equipment like mini excavators. The high pressure and flow capacity should provide reliable output even when the job gets tough.

Been running an older open circuit piston pump on my loader backhoe and it's finally wore out. This a 420 Series unit? Trying to make sure I'm staying in the right family before I order.

Answer by: Customer Support on Nov 6, 2025, 8:55 PM

Yeah, this is a 420 Series open circuit piston pump from the Danfoss/Eaton X20 lineup. The displacement is 3.80 CID, which is 62cc, and it runs under the Code B configuration. If your machine was already set up for a 420 Series pump, this fits right in that platform family. It's built specifically for mobile hydraulic applications, so loader backhoes are well within its intended use.
