ZU4204MB is an Enerpac ZU4 Electric Hydraulic Pump configured around single-acting advance / retract operation. The valve behavior is intentionally simple: advance the single-acting tool, then release pressure for return. Applications that need a hydraulic hold step should use a hold-capable configuration instead.
Model selection becomes clearer against ZU4204JB. In that comparison, pendant control is No on ZU4204MB versus Yes on ZU4204JB.
Why ZU4204MB Is Its Own Configuration
This is a local-control configuration; the operator changes hydraulic direction at the pump valve. The control package is a 3-way, 2-position manual valve for single-acting circuits, providing advance / retract movement.
Check the hydraulic system's total oil demand against the 1.2 gal reservoir before final selection.
Power input is 115V, single phase, 50/60 Hz. That requirement should be matched to the facility, generator or jobsite supply.
