The Esco Disc Coupling DMU Series is a high-performance, non-lubricated, all-metal disc coupling designed for efficient torque transmission with superior torsional stiffness. This coupling utilizes alternating discs positioned between the drive and driven flanges on the same bolt circle, ensuring optimized torque transfer across the disc pack assembly. The coupling accommodates misalignment based on critical design parameters such as pack thickness, disc material, number and placement of drive bolts, allowing it to maintain operational reliability in diverse industrial conditions. Capable of handling torque loads up to 260,000 Nm and bore sizes reaching 370 mm, the DMU Series provides exceptional balance up to AGMA class 9 for sizes up to 85, significantly reducing maintenance requirements and lowering lifecycle costs. The coupling incorporates special plated hardware, with black oxidized and oiled steel components to resist corrosion and extend product durability, making it a highly versatile solution for a myriad of demanding industrial coupling applications.

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 DMU series is a versatile solution, suitable for various applications up to 260,000 Nm (and even larger on request). With impressive torque, bore, and misalignment capabilities, and a high degree of inherent balance (up to AGMA class 9 for sizes up to 85), it excels in reducing maintenance and life cycle costs, making it an ideal choice for a wide range of industrial needs.
