Z-CLASS – A Pump For Every Application
Patented Z-CLASS pump technology provides high by-pass pressures for increased productivity—important in applications using long hose runs and high pressure-drop circuits, like heavy lifting or certain double-acting tools.
Enerpac ZU4 Hydraulic Pumps are built to power small to large torque wrenches. Choosing the right ZU4 torque wrench pump for your application is easy.
Classic Electric Torque Wrench Pump
The Classic has traditional electro-mechanical components (transformers, relays and switches) in place of solid-state electronics. The Classic delivers durable, safe and efficient hydraulic power.
Pro Series Electric Torque Wrench Pump
Digital (LCD) display features a built-in hour meter, pressure display and shows self-diagnostic, cycle-count and low voltage warning information. These premium features are not available on any other pump—anywhere!
AutoCycle feature provides continuous cycle operation of the torque wrench as long as the advance button is pressed. (Pump can be used with or without AutoCycle feature).
Enerpac | Hydraulic Cylinders, Pumps & Valves
Enerpac is the recognised global market leader in high pressure hydraulics. Manufacturer of hydraulic cylinders, pumps, valves, presses, tools, bolting tools, accessories and system components for the manufacturing and construction industries, for productions, maintenance, operation and repair.
The success story dates back to 1910 when, during the dawning of industrialisation in the United States, the originator of our company produced water pumps for the legendary Model T-Ford and other motor cars. Enerpac's reputation in hydraulics started in the early twenties when the first hydraulic jacks were introduced.
Today, dedicated teams of individuals are working on each continent - focusing on the industries needs for hydraulic components, f.e. for the heavy construction trade. Lifting, lowering, pushing, pulling, bending, holding, stressing, cutting, spreading, bolting. Demanding projects worldwide have been accomplished faster and more safely with help from Enerpac's integrated hydraulic systems and equipment. Talk to us about your project.
