Siemens N-ARPEX Couplings



Benefits

N-ARPEX ARN-6 series couplings are outstanding for their application-optimized construction. Types NEN, 

BEB, and MCECM meet the requirements of API 610. Couplings designed according to API 671 are also possible. At speeds above 1800 rpm, the 5-part design with preassembled intermediate unit is used. A special fly-away prevention secures the intermediate spacer if a plate breaks. The use of the N-ARPEX coupling is permitted in potentially explosive atmospheres according to the current ATEX directive.

Application 

The N-ARPEX couplings of the ARN-6 series are used wherever reliable torque transmission is required despite unavoidable displacements of the shafts. They can be used universally in a temperature range of -50 °C (use down to -60 °C on request) up to +280 °C, are torsionally rigid, free of torsional backlash, and permit smooth running at a constant angular velocity. They are not subject to wear, are maintenance-free, and an unlimited service life can be expected if they are properly mounted.

They are particularly suitable for use in pump and compressor drives. Couplings with standardized intermediate spacer lengths are available for this that can be supplied from stock


Main applications of the ARN-6 series:

  • Pumps 
  • Fans 
  • Compressors
  • Generator and turbine drives
  • Axial and radial blowers
  • Paper making and printing machines
  • Mixers, agitators • Extruders
  • Hoisting gear and running gear
  • Marine drives
  • Water screw drives
