NEW A new type, , added to N-EUPEX DK the modular principle of N-EUPEX and the performance & bore capacity of all types increased. 1. NEWTYPE: N-EUPEXDK 1.1 Double-cardanic system With the new double-cardanic design, the coupling compensates for not only a greater range of shaft angle offsets, but also a considerably greater radial offset so that shaft ends can be connected in a manner that offers the drive greater protection. With this two-joint version, compensation for radial offset that occurs between the shaft ends is enabled by a corresponding angle of inclination in the elastomer joints. This increases the range of possible radial offset by more than a multiple of four. Especially with pump solutions, shaft ends that are not 100% in alignment present a significant problem. In this case, the N-EUPEX DK provides a solution for many problems because, depending on the coupling length and size, it enables compensation for a radial offset of up to 3mm. Furthermore, in contrast to the previous N-EUPEX, the new coupling type "DK" makes use of not just one, but two series of elastomer elements, which
