The selection case for ZU4408SB starts with LCD-equipped remote control. This Enerpac ZU4 Electric Hydraulic Pump is one specific hydraulic and electrical arrangement within the broader family. 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.
ZU4420SB is a natural cross-check during selection. Relative to that model, reservoir capacity is 1.8 gal on ZU4408SB versus 5.2 gal on ZU4420SB. This is the model-level change that should be confirmed before ordering.
What the ZU4408SB Model Number Means in Practice
The ZU4 family is designed around a 1.7 hp universal motor and two-stage hydraulic output. The meaningful differences are in how each model controls and supplies the connected tool. For cycle planning, the key output figure is 60 in³/min @ 10,000 psi; the motor size is 1.7 hp. Remote pendant operation allows the operator to remain closer to the hydraulic work while controlling the pump. Its LCD-equipped controls provide operating and diagnostic readouts at the pump.
Confirm that the connected equipment uses the double-acting circuit this model is configured to control.
Valve selection on this model is deliberate: a 4-way, 3-position solenoid valve handles advance / hold / retract operation for double-acting equipment.
