The Esco Disc Coupling DPU Series is a robust, maintenance-free coupling solution designed for high torque transmission applications. Featuring a non-lubricated, all-metal disc pack assembly made of full hard AISI 301 stainless steel, this coupling provides exceptional torsional stiffness and durability. The torque is transferred through alternating discs positioned between drive and driven flanges, securely fastened on the same bolt circle. With a torque capacity of up to 23,100 Nm and bore sizes reaching 220 mm, the DPU series is engineered to handle demanding industrial applications. Its flexible twin element and spacer design offer inherent dynamic balancing properties, eliminating the need for additional balancing at motor speeds and ensuring smooth operation. The coupling’s misalignment capability is influenced by disc pack thickness, disc material, number and layout of drive bolts, making it versatile for diverse operational requirements. It operates efficiently within a temperature range of -40°C to 270°C and complies with API 610 standards, cementing its suitability for heavy-duty industrial equipment. By integrating the proven ESCO Couplings disc pack design, the DPU series enhances reliability, boosts performance, and extends equipment lifespan, making it ideal for power transmission systems in industries such as manufacturing, power plants, and heavy machinery.

Disc couplings are non-lubricated, all-metal components known for their remarkable torsional stiffness. They rely on torque transmission through discs, which alternate between the drive and driven flanges on the same bolt circle within the disc pack assembly. The coupling's misalignment capacity hinges on factors like pack thickness, disc material, the number of drive bolts, and the span between them. The total torque capacity, on the other hand, is determined by the disc pack thickness, total drive bolts, and their arrangement.
Escodisc couplings usually feature two flexible elements and a spacer, ensuring excellent inherent balancing properties and often negating the need for additional balancing at motor speeds. These couplings comply with API 610 standards. The ESCODISC DPU series leverages ESCO Couplings' original disc pack design, enhancing reliability, performance, and equipment longevity.
