Enerpac Announces LU-Series Lightweight Electric Torque Pumps

Industrial tools and heavy lift systems specialist, Enerpac, announces the new LU-Series Electric Torque Pump specifically engineered for intermittent bolting applications. A lightweight, highly portable pump, the LU-Series is a compact alternative to the oversized, continuous-duty pumps traditionally used by maintenance and repair teams, without compromising on performance.

At just 33 lbs empty, the Enerpac LU-Series is designed for safe handling and true portability. Its balanced lifting points and multiple carry points ensure that manoeuvring equipment across ladders, platforms, and tight spaces is simple and ergonomic. Critical components are fully protected, ensuring reliable operation in harsh field conditions where smaller, less robust pumps may fail.

“The Enerpac LU-Series provides a compact, right-sized solution that simplifies the workflow for field technicians and maintenance teams,” said Angie Wallace, Global Product Manager, Enerpac. “Feedback from MRO technicians has included – lightweight and easy to transport thanks to the exposed frame design and multiple secure grip points – responsive and easier to operate remote control even with gloves on – a perfect combination of simplicity, size and weight.”

Intermittent bolting involves periodic or on-demand bolting in response to ongoing maintenance monitoring such as routine torque checks and servicing a limited number of bolts across multiple sites. Traditionally, technicians have had to transport heavy, continuous-duty industrial pumps for these quick, routine checks. The Enerpac LU-Series eliminates this logistical burden by delivering consistent, repeatable torque performance and the exact power required for standard maintenance, packaged in a significantly smaller, lighter footprint.

The introduction of the Enerpac LU-Series fills a critical gap in Enerpac’s wider wind energy and industrial portfolio. While Enerpac’s larger high-flow pumps remain the industry standard for heavy-duty, continuous installation operations, the LU-Series provides a dedicated, highly mobile solution for distributed, application-specific maintenance work.

The Enerpac LU-Series is fully optimized for the rapidly evolving wind energy sector, where technicians face intense pressure regarding mobility, tight maintenance windows, and challenging environments. Developed closely with operators, OEMs, and contractors, the pump’s design directly addresses how crews interact with equipment in real-world conditions.

As maintenance and operation tasks grow larger and installations become more complex, Enerpac continues to support industry growth through practical, application-driven innovation that enhances safety, improves operator efficiency, and maximizes uptime.
