Product information

This diesel hydraulic power unit is built for heavier, stationary, and continuous-duty work. The skid frame is made to be lifted into place by crane or forklift and run hard on site. Compare flow rate, horsepower, and working pressure against your tools to confirm fit.

Applications

Rescue & specialty tooling
Hydraulic breakers
Oilfield

Built for salt water

Underwater cutting, hydraulic breakers, and specialist subsea tooling demand pressure as much as flow. The D-25S12-L7-S runs at 2,500 PSI — the highest working pressure in the HydraTough range — making it the right specification for marine and underwater contractors running high-pressure hydraulic equipment below the waterline.

Designed to be serviced

Every HydraTough unit is built for straightforward field servicing. Parts are stocked in the US. Manuals are free — no account or registration required.
