If single-acting advance / retract operation is the defining requirement, ZU4208JB is the Enerpac ZU4 Electric Hydraulic Pump version to evaluate. The 1.8 gal reservoir sits between the smallest and largest capacities offered in this group, making oil-volume demand an important comparison point.
Model selection becomes clearer against ZU4204JB. In that comparison, reservoir capacity is 1.8 gal on ZU4208JB versus 1.2 gal on ZU4204JB.
Understanding the ZU4208JB Arrangement
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. Its motor package is configured for 115V, single phase, 50/60 Hz, which is often the deciding factor between closely related model numbers. With a 1.8 gal reservoir, this version occupies a specific capacity point within the series; reservoir sizing should follow the oil demand of the full circuit.
Verify site power against the 115V requirement; a nearby suffix may represent a different electrical version.
