For a system that requires double-acting advance / hold / retract operation, PUJ1400B is the corresponding Enerpac Economy Electric Hydraulic Pump configuration. The hold position is useful in a double-acting circuit when the cylinder must be stopped between powered advance and powered return movements.
If the shortlist includes PUJ1400E, focus on the configuration change: input voltage is 115V on PUJ1400B versus 230V on PUJ1400E. The remaining shared family characteristics should not obscure that difference.
How to Choose the PUJ1400B Version
Within the PU family, PUJ models are the manual-valve versions. Cylinder compatibility and valve geometry are the main differences between individual pumps. Valve selection on this model is deliberate: a 4-way, 3-position manual valve handles advance / hold / retract operation for double-acting equipment. Power input is 115V, single phase, 50/60 Hz. That requirement should be matched to the facility, generator or jobsite supply.
Verify site power against the 115V requirement; a nearby suffix may represent a different electrical version.
