FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARP-6 Series General information © Siemens AG 2011 ■ Design NAN: The design of an ARPEX NAN coupling of the ARP-6 series is shown in the following illustration. The plate packs are bolted alternately between the flanges of the coupling hubs and the intermediate spacer. Up to size 298-6 close-fitting bolts and from size 325-6 conical screw connections are used for fastening. The intermediate spacer is available from stock in various fixed lengths. Hubs are designed with threaded pull-off holes. Type MCECM MCECM: The design of an ARPEX MCECM coupling of the ARP-6 series is shown in the following illustration. Bolted between two hubs is the CEC transmission unit, the preassembled plate packs of which are bolted alternately between flanges and intermediate spacer. Up to size 275-6 close-fitting bolts and from size 310-6 conical screw connections are used for fastening. The intermediate spacer is available from stock in various fixed lengths. Jumbo hubs for large bore diameters can be optionally used.
