Sapphire and Ceramic Nozzles

Complete range for all applications

For high and ultra high pressures up to 4000 bar it is very common to use more exotic materials like sapphire or ceramic. The benefits of these materials are that they are harder and therefore the nozzles have a longer lifetime. Ceramic has also the benefit to give a very long and sharp jet. Further ceramic is suitable for handling small particles in the water (recycling sewer cleaning trucks) and still achieving a long life time. The sapphire or ceramic inserts are fixed and glued in stainless steel holders to suit the application.
