Bring hydraulic bolting power closer to the work with the Enerpac LU2504TE-QR Electric Torque Wrench Pump. Built for intermittent torque wrench applications, this compact pump gives maintenance technicians and industrial service crews a practical alternative to larger hydraulic power units that add unnecessary size and weight to routine bolting jobs.
The LU2504TE-QR operates from a 208–240V single-phase electrical supply and develops hydraulic pressure up to 10,000 PSI. Its 0.73-horsepower electric motor and solenoid-operated valve provide powered control for compatible double-acting hydraulic torque wrenches used in equipment maintenance, flange bolting, machinery repair, and other controlled fastening applications.
A two-stage hydraulic system helps reduce time spent waiting for the tool to advance. The pump initially delivers up to 190 cubic inches per minute under no-load conditions, rapidly moving the torque wrench into position. As system resistance increases, flow transitions to 20 cubic inches per minute at rated pressure for the controlled application of torque.
Rather than using an oversized oil reservoir, Enerpac equips the LU2504TE-QR with a compact 3-liter aluminum reservoir containing approximately 1.9 liters of usable oil. This application-specific design keeps the overall package manageable while supplying the oil capacity needed for common hydraulic torque wrench operations.
Field handling is supported by angled carrying handles, multiple lifting locations, and a protective roll cage surrounding the pump. These features make it easier to reposition the unit around machinery, plant floors and service areas while helping protect internal components from impact during transportation and use. A removable front plate also provides more direct access when inspection or maintenance is required.
Operators can monitor hydraulic pressure through the upward-facing 4-inch glycerin-filled gauge. Its angled position improves readability from a normal working stance, reducing the need to lean over the pump during pressure adjustments or tool operation.
Pump functions are managed through a handheld pendant with a detachable 20-foot control cord. The extended lead allows the technician to operate the connected torque wrench from a practical working position, while the integrated pendant pocket provides a dedicated storage location when the equipment is being moved or stored.
At approximately 41 pounds, the Enerpac LU2504TE-QR combines industrial hydraulic performance with a form factor designed around portability. It is a strong fit for maintenance teams that perform periodic bolting work and need a rugged, easy-to-deploy electric torque pump without the bulk of a continuous-production power unit.
