Product information

This portable diesel hydraulic power unit runs hydraulic tools across demanding job-site conditions. The wheeled frame moves easily over rough ground, and the 0–12 GPM (variable) output matches a range of tools. Compare flow rate, horsepower, and circuit type against your tools to confirm fit.

Applications

Hydraulic breakers
Underground boring
Hydraulic excavation
Marine & underwater
Oilfield

Built for salt water

Marine and underwater crews rarely run just one tool. The D-23S12-J5-W’s variable 0–12 GPM flow means it adapts to whatever hydraulic equipment is in use — from lighter surface tools to heavier underwater cutting and breaker equipment. One diesel unit that covers the range of tools your marine operation demands.

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.
