ZE3304MB is an Enerpac Electric Hydraulic Pump configured around single-acting advance / hold / retract operation. This is a hold-capable single-acting configuration, which matters when the application needs to stop and maintain cylinder position before pressure is released for return.
Choosing ZE3304MB Over a Near-Match
The ZE platform is built around configurable hydraulic control. Manual, solenoid and Venturi-valve options let the same pump family serve different cylinder and operating requirements. Valve selection on this model is deliberate: a 3-way, 3-position manual valve handles advance / hold / retract operation for single-acting equipment. Power input is 115V, single phase, 50/60 Hz. That requirement should be matched to the facility, generator or jobsite supply.
Confirm that the connected equipment uses the single-acting circuit this model is configured to control.
If the shortlist includes ZE3308MB, focus on the configuration change: reservoir capacity is 1.2 gal on ZE3304MB versus 1.8 gal on ZE3308MB. The remaining shared family characteristics should not obscure that difference.
