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.
All ZU4 Torque Pump Models
- Features Z-Class high-efficiency pump design for higher oil flow and bypass pressure, cooler running and requires 18% less current draw than comparable pumps
- Powerful 1.7 hp universal electric motor provides high power-to-weight ratio and excellent low-voltage operating characteristics
- High-strength, molded composite shroud protects motor and electrical components, while providing an ergonomic, nonconductive handle for easy transport
- Low-voltage pendant provides additional safety for the operator
- Relief valve adjustment range 1800 - 10,000 psi
Pro-Series Only
- LCD readout provides pressure and torque display, and diagnostic and readout capabilities never offered before on a portable electric pump
