Start with what the hydraulic circuit needs: ZU4120DB is an Enerpac ZU4 Electric Hydraulic Pump arranged for LCD-equipped remote control. Because this model carries LCD control, it offers a different operator interface from the classic/non-LCD variants in the same family.
The control package is a 3-way, 2-position dump valve for single-acting circuits, providing advance / retract movement.
ZU4104DB is a natural cross-check during selection. Relative to that model, reservoir capacity is 5.2 gal on ZU4120DB versus 1.2 gal on ZU4104DB. This is the model-level change that should be confirmed before ordering.
How to Choose the ZU4120DB Version
A 1.7 hp motor drives the pump, with rated-pressure output specified at 60 in³/min @ 10,000 psi. The pendant moves pump control away from the power unit, which is useful when the operator needs to watch the tool or cylinder. Its LCD-equipped controls provide operating and diagnostic readouts at the pump.
Confirm that the connected equipment uses the single-acting circuit this model is configured to control.
