If LCD-equipped remote control is the defining requirement, ZU4204SB is the Enerpac ZU4 Electric Hydraulic Pump version to evaluate. This is a hold-capable single-acting configuration, which matters when the application needs to stop and maintain cylinder position before pressure is released for return.
ZU4208SB is a natural cross-check during selection. Relative to that model, reservoir capacity is 1.2 gal on ZU4204SB versus 1.8 gal on ZU4208SB. This is the model-level change that should be confirmed before ordering.
Understanding the ZU4204SB 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. With a 1.2 gal reservoir, this version occupies a specific capacity point within the series; reservoir sizing should follow the oil demand of the full circuit. A 1.7 hp motor drives the pump, with rated-pressure output specified at 60 in³/min @ 10,000 psi.
Verify site power against the 115V requirement; a nearby suffix may represent a different electrical version.
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.
