DANFOSS / EATON-3.00 CID (49CC) 420 CODEB

Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton X20 420 Series open circuit piston pump delivers a displacement of 3.00 CID (49cc) with high pressure and flow capacity suited to heavy-duty cycling. The 420 Code B configuration is built for equipment that requires responsive, reliable hydraulic power across variable load conditions.

Typical applications include loader backhoes, agriculture tractors, crawler dozers, mini excavators, concrete and asphalt pavers, container handling equipment, and railroad machinery. The pump is also used in vibratory cable plows, mining and tunnel boring equipment, utility boom trucks, and rough terrain forklifts, making it a versatile choice across mobile and off-road platforms.

Advanced control options support efficient power management, and the pump's response and recovery characteristics make it well suited to applications where hydraulic demand changes rapidly. A product width of 5.75 inches is noted for installation planning purposes.

Question by: Lyle H on Oct 24, 2025, 4:10 PM
Got a mini excavator that's been burning through pumps, would this 420 Series unit hold up to that kind of hard cycling?
Answer by: Customer Support on Oct 26, 2025, 6:39 AM
Heavy cycling is exactly what this pump was built around. The X20 420 Series is rated for high pressure and high flow, and mini excavators are actually called out as one of its core applications. The response and recovery characteristics are specifically noted as among the fastest available, which matters a lot when hydraulic demand is shifting constantly during digging and lifting cycles. For a machine that's working hard day in and day out, this is a reasonable fit.
