Start with what the hydraulic circuit needs: ZE3440MB is an Enerpac Electric Hydraulic Pump arranged for double-acting advance / hold / retract operation. Its four-way style of control is appropriate where both directions are hydraulically powered, while the center hold position allows movement to be paused between commands.
The 10.3 gal reservoir determines how much oil is available to the connected hydraulic circuit and should be checked against total cylinder or tool volume. For cycle planning, the key output figure is 40 in³/min @ 10,000 psi; the motor size is 1 hp.
ZE3404MB is a natural cross-check during selection. Relative to that model, reservoir capacity is 10.3 gal on ZE3440MB versus 1.2 gal on ZE3404MB. This is the model-level change that should be confirmed before ordering.
Hydraulic direction is controlled locally at the pump rather than from a pendant.
Confirm that the connected equipment uses the double-acting circuit this model is configured to control.
