Coupling suitable for use in potentially explosive atmospheres. Complies with the current ATEX Directive for: II 2GEx h IICT6 ... T2Gb X I M2 Ex hMb X Benefits N-ARPEX couplings of theARN-6/-8/-10 series are outstanding for their application-optimized construction. The NEN, BEB, MCECM, MFEFM series meet the requirement of API 610. Couplings in accordance withAPI 671 are also possible. For speeds of over 1,800 rpm the five-part version with pre-assembled intermediate unit is used. Aspecial catching device acts to secure the intermediate spacer in the event of plate breakage. Application of the N-ARPEX couplings in potentially explosive atmospheres in accordance with the current ATEXDirective are available. Application N-ARPEX couplings of the ARN-6/-8/-10 series are used wherever reliable torque transmission is called for, even in cases of often unavoidable shaft misalignment. They are universally applicable over a temperature range of from -50 °C (or even as low as -60 °C on request) up to +280 °C, are torsionally rigid, free of torsional backlash and enable quiet running at a constant angular velocity. They are wear-free and maintenance-free and, if correctly fitted, can be expected to have an unlimited service life. Special consideration is given for use in pump and compressor drives. For this type of application are couplings with standardised intermediate spacer lengths from stock (see following tables).
