Safety-related information Monro-Jet

We have now received a burst Monro-Jet nozzle body from a low-cost manufacturer, which we have had tested by the neutral test laboratory MatExpert.

The material 1.4305, that has been used for the production of the Monro-Jet nozzle copy does not meet the requirements for a water jet nozzle with a working pressure up to 2500 bar at all.

The picture alonside shows a nozzle body that has burst due to a low-cost manufacturer not using the appropriate material. This is extremely problematic, since the longitudinal crack in the nozzle body poses a great risk of injury to itself and the entire environment. Such a spontaneous breakage only occurs if the mechanical properties of the material have not been considered. In this case, a material was used which, as already mentioned, has a lower tensile strength than the original material for Monro-Jet nozzle bodies. This led to an overload of the material which subsequently broke / cracked. In the event of such a breakage, all the energy in the form of high pressure of up to 2500 bar in the housing is released at one stroke.
