Series: ZU4T

Product Line: Bolting Tools

2. Desciption: ZU4-Series Electric Hydraulic Torque Wrench Pumps use Enerpac market leading Z-Class hydraulic technology. This provides higher oil flow and by-pass pressure, cooler running, and 18% less current draw than comparable pumps.

Within the ZU4-Series are ‘Classic’ and ‘Pro Series’ models to choose from.

The ZU4 Classic includes an analog pressure gauge and traditional electro-mechanical components (transformers, relays and switches) in place of solid state electronics. The Classic delivers reliable, safe, and efficient hydraulic power.

The Pro Series features a digital (LCD) display, with a built-in hour meter, and shows pressure, torque, diagnostics, cycle-count, and low voltage warning information. Also included is the auto cycle feature to enable continuous cycle operation of your torque wrench. The pump can be used with or without the auto cycle feature.
