Start with what the hydraulic circuit needs: ZE3320MB is an Enerpac Electric Hydraulic Pump arranged for single-acting advance / hold / retract operation. The 5.2 gal reservoir sits between the smallest and largest capacities offered in this group, making oil-volume demand an important comparison point.
Where ZE3320MB Fits in the Pump Family
Enerpac’s ZE-Series ordering structure separates models by flow group, valve arrangement, reservoir size and control package. Those differences matter more than the shared family name when choosing a pump. This is a local-control configuration; the operator changes hydraulic direction at the pump valve. Valve selection on this model is deliberate: a 3-way, 3-position manual valve handles advance / hold / retract operation for single-acting equipment.
Model selection becomes clearer against ZE3304MB. In that comparison, reservoir capacity is 5.2 gal on ZE3320MB versus 1.2 gal on ZE3304MB.
Check the hydraulic system's total oil demand against the 5.2 gal reservoir before final selection.
