NORMS AND REGULATIONS Waterjet cutting is widely accepted as one of the best methods for precision cutting – especially for materials sensitive to heat. Originally suited for softer materials, the addition of abrasives to the cutting jet means that today’s jet cutters can tackle the hardest of metals, glass and stonewith accuracy and at speed. ABOUT WATERJET CUTTING • Removing impurities prevents damage to the waterjet nozzle • Softening reduces calcium and magnesium ions at speed • Reverse osmosis reduces most dissolved solids for optimum water quality and machine efficiency • Treatment systems are low maintenance requiring only routine filter replacement • Pre-treated water results in maximum up-time for jet cutting machines • Operators report cost savings on nozzle replacements WATERJET CUTTING BENEFITS OF PRE-TREATING WATER FOR JET CUTTING Before reaching the pump and jet cutting nozzle, mains water can be pre-treated for ultimatemachine efficiency. The next page illustrates howPentair products can be used in that treatment process. WATER TREATMENT PROCESS FOR WATERJET CUTTING MACHINES WHAT IS IT? Water is pressurized up to 6000 bar and passed through a small diameter nozzle at around 1000 meters per second. It is fast and accurate, yet gentle on materials as it generates little heat. PURE WATERJET CUTTING Using water only, the nozzle can be relatively small and the jet very fine (as little as 0.1 mm) so this is highly effective for thinner materials. This method creates no dust or toxic gases so is more environmentally friendly. ABRASIVE WATERJET CUTTING The addition of an abrasive garnet, drawn in and mixed with the waterjet as it passes through the nozzle, makes possible a more powerful, deeper cut. Advances in pump and nozzle technology mean this method of waterjet cutting is more widely adopted. Operating in excess of 6000 bar with a usage of up to 19 liters per minute, these hi-spec machines require a steady supply of pure water. Impurities can do serious damage, quickly wearing out costly nozzles. If a water quality test shows excessive minerals or contamination, then filtration, softening and reverse osmosis units may prevent costly maintenance over time. Many waterjet cutting operations choose to pre- treat their water, and for some it is the only option. Here we examine the treatment possibilities and explain how Pentair solutions can help.
