The selection case for ZU4408JB starts with double-acting advance / hold / retract operation. This Enerpac ZU4 Electric Hydraulic Pump is one specific hydraulic and electrical arrangement within the broader family. The 1.8 gal reservoir sits between the smallest and largest capacities offered in this group, making oil-volume demand an important comparison point.
ZU4408MB is a natural cross-check during selection. Relative to that model, pendant control is Yes on ZU4408JB versus No on ZU4408MB. This is the model-level change that should be confirmed before ordering.
The Role of ZU4408JB in the Series
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. The 1.8 gal reservoir determines how much oil is available to the connected hydraulic circuit and should be checked against total cylinder or tool volume. At rated pressure, Enerpac specifies 60 in³/min @ 10,000 psi from the 1.7 hp motor package.
Verify site power against the 115V requirement; a nearby suffix may represent a different electrical version.
