Enerpac (A Division of Actuant Corp) presents a new range of air hydraulic torque wrench pumps designed for reliable high performance, ease of use and safety in challenging and potentially hazardous environments.
Enerpac is a major supplier of high-pressure (700 bar) hydraulic equipment including precision hydraulic cylinders, tools and safety equipment.
Suitable for use in oil and gas, energy, mining, and onshore and offshore infrastructure projects, the ZA4 series ZA4208TX-QE100 air hydraulic torque wrench pumps are ATEX 95 certified for use in potentially explosive atmospheres.
Featuring a high efficiency pump design with higher oil flow and bypass pressure, the ZA4 series torque wrench pumps offer enhanced two-speed operation to reduce cycle time for improved productivity.
Custom-engineered for extended operation in its first stage, the new ZA4 modular pump delivers extended performance in ranges required by users working on maintenance and fabrication applications such as pipelines, pressure vessels, tanks, metal structures, rigs, and onshore and offshore machinery.
According to Enerpac Manager, Oil and Gas Industry, Mr Slade Greenaway, Wilkerson reclassifer exhaust technology has been employed to prevent motors freezing as well as to reduce exhaust noise while a larger air motor piston allows the pump to operate with air input as low as 2 bar.
He adds that a key advantage of lower operating pressures is that multiple torque wrenches can be operated from a single source of compressed air.
The new ZA4208TX-QE100 model pump is part of the ongoing development of the broader ZA4 series, which is available in reservoir capacities from 4 to 40 litres.
Key benefits of ZA4 series torque wrench pumps:
- Simplified air logic circuit increases efficiency and reduces redundant components
- Pressure gauges can be re-calibrated on site
- Enhanced oil mist lubricator prevents adjusting screw failure
- Stainless steel relief adjuster valve and plated bolts for durability
- Roll frame permits crow’s foot connector to be screwed directly into the air outlet
- Air pressure gauge mounted on 45-degree fitting for easy reading
