Start with what the hydraulic circuit needs: PUJ1400E is an Enerpac Economy Electric Hydraulic Pump arranged for double-acting advance / hold / retract operation. The hold position is useful in a double-acting circuit when the cylinder must be stopped between powered advance and powered return movements.
Control and Power Decisions for PUJ1400E
The control package is a 4-way, 3-position manual valve for double-acting circuits, providing advance / hold / retract movement. The electrical requirement is 230V, single phase, 50/60 Hz, so site power should be confirmed before the pump is specified.
Confirm that the connected equipment uses the double-acting circuit this model is configured to control.
The adjacent model PUJ1400B helps clarify the choice. input voltage is 230V on PUJ1400E versus 115V on PUJ1400B; that is the key separation between these two otherwise related pumps.
