Germany: Flender has increased the torque of its N-Arpex coupling product range with two new designs featuring eight and ten bolting points. N-Arpex now covers a diameter up to 988mm and a torque up to 2MNm. The compact design and enhanced bore capacities also enable a leap in size. A smaller coupling transmits a higher torque compared to the predecessor model. The steel disc coupling is suitable for use in drive applications including pumps, fans, compressors, generators, turbines, and paper and printing machines.
Other improvements include a more compact Flender conical bolt connection for the plate packs. With the two new N-Arpex couplings, Flender has introduced a modular system that increases the number of available types as well as reducing the number of components required. The three standard series of the predecessor Arpex merge into one N-Arpex series. The new series of couplings has also been designed for use in potentially explosive environments as defined in directive 2014/34/EU and fulfil the requirements of API610/ISO13709 and API671/ISO10441.
