Disc Couplings are made of 100% metal, have no lubrication, and are rigid in torsion. The drive and driven flanges of the disc pack assembly are alternately fitted with discs (on the same bolt circle) to transmit torque.

The misalignment capacity depends on the pack thickness, the disc material, the amount of drive bolts and the free span of the material between the drive bolts.

The total torque capacity depends on the disc pack thickness, total number of drive bolts and their bolt circle. Disc coupling will in most cases have two flexible elements and a spacer. As all parts are positively connected, the disc coupling ensures good inherent balancing properties and is hence often used at motor speeds without any additional balancing. Escodisc couplings meet the API 610 standards. 

The ESCODISC DPU series is built around ESCO Couplings genuine and original disc pack sub assembly design. This design with optimized disc shape and thickness, is factory assembled and secured by shipping screws against damages, minimizes assembly errors, simplifies coupling mounting and guarantees worry free performance, low operating costs as well as long life of the connected equipment.
