In several industrial applications, water is the only viable pressure medium. Three examples from the field: 🔥 Forging presses and hot rolling mills: An oil leak near glowing steel means acute fire hazard. A water leak has no consequences. ⛏️ Underground longwall mining: Hundreds of hydraulic cylinders with diameters up to 500 mm support the roof. They are supplied by water-hydraulic pump stations with several thousand kW of total input power. Oil would be an unacceptable fire risk in this environment. 🏭 Processes with contamination risk: Wherever an oil spill would endanger product or environment, water remains the medium of choice. The technical case is just as strong: ✅ Low compressibility delivers direct kinetics and precise closed-loop position control ✅ Low viscosity enables higher system efficiency than oil hydraulics ✅ Water can be pumped at high velocities, allowing smaller pipe diameters ✅ The fluid is inexpensive and easy to dispose of. With system volumes of several thousand litres, that is a real cost factor. Water forgives no design errors, though. It is corrosive, non-lubricating, and cavitation-induced pressure shocks hit the system undamped, at full force. That is why KAMAT develops every component for water-hydraulic systems in-house: stainless steel wetted parts, solid ceramic plungers, drive powers up to 3,000 kW at pressures up to 4,000 bar. Engineering for Engineers, leading in water hydraulics for decades. 👉 Where are you still running oil hydraulics today, even though fire safety or contamination is an issue? #KAMAT #HighPressureTechnology #WaterHydraulics #Mining #MetalsIndustry #EngineeringForEngineers
