To remove coatings, impurities, or soft materials, a pure water jet can be utilized. Due to its high kinetic energy, the workpiece is subjected to shock loads when the jet hits it. Flat jet nozzles or rotating nozzle heads are usually used for removal. By using a pure water jet, the process can be designed so that the removal is selective, i.e. does not damage selected components of composite materials.

For cleaning or material removal applications, powerful directly-driven high-pressure pumps are typically employed. To achieve high cleaning or material removal effectiveness, process parameters are often optimized towards high water flow rates. The additional use of multiple simultaneously operated water nozzles, such as on rotating nozzle heads, requires additional power. In industrial applications, pumps with over 1,000 kW hydraulic power are frequently used in such processes. At the Institute for Materials Science, a plunger pump with 110 kW hydraulic power and electrical power supply is available for research purposes.
