ZU4704PB occupies a distinct point in the Enerpac ZU4 Electric Hydraulic Pump family because of its single-acting advance / retract operation configuration. 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.
The 1.2 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.
A practical comparison is ZU4204MB. Between the two, pendant control is Yes on ZU4704PB versus No on ZU4204MB. That gives the buyer a concrete reason to choose one model over the other.
Verify site power against the 115V requirement; a nearby suffix may represent a different electrical version.
