Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton-420 Tandem Pump is a high-pressure open circuit piston pump built for equipment that requires fast response and reliable flow recovery. Its advanced control options support efficient power management across a wide range of load conditions.

This pump is well suited to heavy-duty mobile equipment including loader backhoes, crawler dozers, mini excavators, articulated haulers, and concrete and asphalt pavers. It also serves agricultural tractors, railroad equipment, container handling machinery, vibratory cable plows, feller/bunchers, and utility boom trucks. The tandem configuration makes it applicable where multiple hydraulic circuits must be driven from a single power source.

Product Questions & Answers (2)

Question by: Daryl H on Jan 17, 2026, 3:03 PM
We run a couple loader backhoes and a mini excavator off the same power source on a job site. This tandem pump setup, does it handle driving multiple hydraulic circuits at once or is that not really what it's built for?
Answer by: Customer Support on Jan 19, 2026, 7:58 AM
Running multiple circuits from a single power source is exactly the kind of situation this pump is built for. The tandem configuration is specifically meant for equipment that needs to drive more than one hydraulic circuit at the same time without splitting off to a second pump unit. Loader backhoes and mini excavators are both listed application fits for this pump, so that pairing makes a lot of practical sense.
