PST4 DN39 CS: A SCREW COUPLING WITH A SAFETY SYSTEM

13 November, 2020

DNP has announced a product designed for earth-moving machinery in general but above all to be used on hammers and wherever it is necessary to have big ¬ow rates (379 l/min.) at high pressure (30 MPa) in the presence of strong vibrations. DNP says it has therefore created a screw coupling with a safety system capable of preventing the coupling from unscrewing where the locking ring nut system is as simple as it is effective and this has allowed the problem to be easily solved.


DNP has also inserted a mechanism in the male to reduce the residual pressure, which facilitates the connection despite the large size of the coupling.
