New LU-Series Lightweight Torque Pump

Enerpac has unveiled an exciting new member of its torque pump family. The LU-Series Lightweight Torque Pump is engineered specifically for intermittent bolting projects - for bolting crews who demand speed and reliability, without excess size, weight, or complexity.

This easy-to-use solution is ideal for crews handling maintenance and repair work. It delivers the portability and speed bolting technicians expect and is backed by Enerpac's market-leading durability for unmatched reliability in the field.

Bolting technicians often struggle with oversized, bulky torque pumps that are difficult to carry to hard-to-reach work areas, increasing setup time, fatigue, and handling risks. Many units are overengineered for the task, adding unnecessary weight and complexity, while others fail to deliver the promised performance on site. This disconnect between design and real-world application was a key factor in the development of the new LU-Series torque pump.

Portability at this level doesn't happen by accident. It starts by putting the operator at the center of every design decision. At just 41 lbs (18.8 kg) fully equipped, it can be carried by one person, ensuring safe and predictable handling. A compact footprint, balanced lifting points, and a right-sized reservoir make movement, set-up, and repositioning simple – without unexpected weight or awkward lifting.

A pump that's easier to carry shouldn't come at the expense of durability. Engineered for real-world jobsite conditions, the LU-Series is tested across demanding duty cycles for proven long-lasting performance. Tested to 50,000+ cycles for intermittent duty use, and designed to withstand typical knocks and accidental drops, you can be assured of long-term durability and performance. Additionally, critical components are protected by the front shield from potential impact and damage on harsh industrial sites, and the pump will perform reliably in extreme temperatures ranging from -30°F to 122°F.

While portability is a key advantage of the LU-Series pump, its benefits go beyond mobility. The LU-Series features an integrated pocket that keeps the pendant securely docked and off the ground, ensuring it stays protected yet easily accessible. An upward-facing, glycerin-filled, angled gauge provides clear visibility from ground level, eliminating the need for crouching or straining. To further enhance usability, quick-disconnect couplers, a quick-release gauge, and a detachable pendant simplify servicing and calibration, helping to minimize downtime and deliver a smooth, efficient, user-friendly experience.

In many bolting scenarios, selecting the right equipment size can have a direct impact on efficiency and usability. For smaller, localized torque applications, continuous-duty high-flow pumps are often oversized. The LU-Series Pump provides a compact, right-sized solution, delivering faster setup, easier transport, and efficient performance without excess size, weight, or complexity. The result is a more streamlined 2-speed solution engineered for real torque-wrench duty cycles, that reaches usable speed quickly, supporting reliable and predictable performance on the job.

Some pumps overpromise on paper, but what matters is how they perform in your hands, on your site, and under pressure. With the LU-Series the advertised specification is exactly what you get on site: predictable performance, straightforward operation, and dependable results. No inflated claims and no hidden extras.
