ZE4440SB is a model-specific Enerpac Electric Hydraulic Pump choice for LCD-equipped remote control. The LCD-equipped control package is a meaningful upgrade when operating information and diagnostics at the pump are useful to the application.
What the ZE4440SB Model Number Means in Practice
Within the ZE range, valve choice and flow group are major selection points. ZE3 and ZE4 models use different motor sizes and rated-pressure flow levels. Hydraulic direction comes from a 4-way, 3-position solenoid valve, matched to double-acting service and advance / hold / retract operation. This model is built for 115V, single phase, 50/60 Hz power, making the electrical supply an important distinction from otherwise similar variants.
Check the hydraulic system's total oil demand against the 10.3 gal reservoir before final selection.
Compare this model with ZE4408SB if the choices look similar. reservoir capacity is 10.3 gal on ZE4440SB versus 1.8 gal on ZE4408SB. That distinction is more important than the shared series name when matching the pump to the system.
