                           Grindaix cleaning nozzles are available in two types. Low pressure: Here we achieve the same
                           cleaning performance at a supply pressure of below 25 bar and can thus use more cost-efficient
                           centrifugal pumps which are less prone to wear. High-pressure type: Supplied upon customer re-
                           quest. Here, screw spindle pumps are used, as considerably higher lubricoolant pressures (>25 bar)
                           are needed.

                           Although at 20 bar, the operating pressure of the Grindaix cleaning nozzles is still high – and this is
                           often necessary for achieving an optimum cleaning result – our cleaning nozzles only consume low                                          GEAR TOOTH

                           When cleaning grinding wheels, the orientation of the cleaning nozzles is also important. Here, it is
                           possible to spray in the same direction that the grinding wheel is rotating or counter to it, or else
                           vertically onto the grinding rim. It is also possible to use one row of cleaning nozzles or several.                                     Our high-pressure cleaning nozzle RD-LP 70 is a flexible solution for cleaning
