The value of ZU4104DB is in the exact combination of controls and power it provides. This Enerpac ZU4 Electric Hydraulic Pump is built around 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.
What the ZU4104DB Model Number Means in Practice
If the shortlist includes ZU4108DB, focus on the configuration change: reservoir capacity is 1.2 gal on ZU4104DB versus 1.8 gal on ZU4108DB. The remaining shared family characteristics should not obscure that difference.
Enerpac configures ZU4 pumps for several hydraulic tasks, including standard cylinder operation and torque-wrench service. The valve and control package identify the intended use. Pendant control lets the operator command the pump without standing at the valve body. The LCD control package adds pump status and diagnostic information. Hydraulic direction comes from a 3-way, 2-position dump valve, matched to single-acting service and advance / retract operation.
Its motor package is configured for 115V, single phase, 50/60 Hz, which is often the deciding factor between closely related model numbers.
Verify site power against the 115V requirement; a nearby suffix may represent a different electrical version.
