Ask A Question

Description & Features

Rated at 4.88 CID (80cc) displacement, this open circuit piston pump is built for demanding mobile hydraulic applications where pressure capacity and responsive performance are priorities. The Danfoss / Eaton-4.88 CID(80CC)420 Code C belongs to the X20 420 Series and is designed for high-cycle, variable-load environments common in heavy mobile equipment.

Typical applications include loader backhoes, agriculture tractors, crawler dozers, mini excavators, articulated haulers, concrete and asphalt pavers, and container handling equipment. It is also well suited for railroad equipment, vibratory cable plows, mining machinery, tunnel boring equipment, utility boom trucks, and rough terrain forklifts.

Advanced control options support efficiency across varied duty cycles, and the pump is engineered for fast response and recovery, a relevant characteristic in mobile equipment where load conditions change frequently. Product width is 5.75 inches.

Question by: Donna M on Feb 14, 2026, 8:30 PM
Got a mini excavator that's been running a smaller pump and we're looking to step up the performance, would the 80cc displacement on this one handle higher-demand work cycles without bogging down?
Answer by: Customer Support on Feb 16, 2026, 6:45 AM
At 4.88 cubic inch displacement, this pump sits in a range well suited for mobile equipment that sees variable and demanding load conditions. Mini excavators are actually listed as one of the target applications for this series, and the X20 420 design is built around fast response and recovery when load conditions shift quickly. So yes, stepping up to this size should give you more headroom for higher-demand cycles compared to a smaller unit.
