ZU4208SB is best understood by its configuration rather than by the series name alone. This Enerpac ZU4 Electric Hydraulic Pump is set up for LCD-equipped remote control. For a single-acting circuit, the hold function separates this model from simple dump-style pumps by allowing hydraulic pressure to be maintained between advance and return.
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. Valve selection on this model is deliberate: a 3-way, 2-position solenoid valve handles advance / hold / retract operation for single-acting equipment. This model is built for 115V, single phase, 50/60 Hz power, making the electrical supply an important distinction from otherwise similar variants.
Valve, Reservoir and Power Fit for ZU4208SB
The adjacent model ZU41108SB helps clarify the choice. valve arrangement is 3-way, 2-position solenoid valve on ZU4208SB versus 3-way, 3-position solenoid Venturi valve on ZU41108SB; that is the key separation between these two otherwise related pumps.
Check the hydraulic system's total oil demand against the 1.8 gal reservoir before final selection.
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.
