The anticipated growth in the diaphragm coupling in the turbo machinery market is expected to be fueled by the demand for high-performance equipment. High-performance diaphragm couplings, designed to handle misalignment based on the thickness distribution of the diaphragm, play a crucial role in applications such as oil and gas turbines. In this context, they transmit power from the compressor to the turbine and absorb displacement for proper torque transmission. An illustrative example is the performance reported by Volvo Construction Equipment in January 2023, which indicated a 27% increase in net sales in the fourth quarter of 2022, totaling SEK 27.59 billion ($21,812 million). This growth was attributed to contributions from both machine sales and the service sector. Adjusted for currency changes, net sales witnessed a 13% increase, with net machine sales rising by 15%. The demand for high-performance equipment in the oil and gas industry stands out as a significant driver behind the growth of diaphragm couplings in the turbo machinery market.

The increasing focus on renewable energy integration is expected to contribute to the growth of diaphragm couplings in the turbo machinery market. Renewable energy integration involves the incorporation of sources such as wind, solar, geothermal, and hydroelectric power into the existing electric grid. Diaphragm couplings emerge as a favorable choice for renewable energy applications, including solar and wind power, owing to their features such as low backlash, low vibration transmission, high torque capacity, and sustainability benefits. According to the Energy Information Administration, it is anticipated that 16% of total energy generation in 2023 will come from renewable sources such as wind and solar, up from 14% in 2022. The increasing focus on renewable energy integration is thus driving the growth of diaphragm couplings in the turbo machinery market.

Product innovation is a significant trend gaining traction in the diaphragm coupling segment of the turbomachinery market. Leading companies in this sector are creating innovative products to maintain their competitive edge. For example, in April 2024, SKF, a Sweden-based company, launched a series of diaphragm couplings designed to offer cost-effective, lubrication-free operation for high-torque applications with medium torsional stiffness. These couplings are available in various configurations, including single and double disc designs, and can be installed in both horizontal and vertical orientations, supporting load capacities of up to 178 kNm. Made with all-steel mechanical components, SKF diaphragm couplings ensure reliable performance and are particularly suited for high-speed applications due to their two-plane dynamic balance.

The increasing demand within the oil and gas industry is anticipated to be a driving force behind the growth of diaphragm couplings in the turbomachinery market. The oil and gas industry encompasses various operations related to the exploration, extraction, refining, transportation, and marketing of petroleum products. In this industry, equipment often faces misalignments due to factors such as ground settling, thermal expansion, or vibrations. Diaphragm couplings, recognized for their flexibility in accommodating both angular and parallel misalignments, play a crucial role in ensuring the proper functioning of turbomachinery in dynamic environments. For instance, as of November 2023, the UAE was reported to produce an average of 3.2 million barrels of petroleum and liquids per day, emphasizing the substantial demand in the oil and gas sector.

A diaphragm coupling is a flexible coupling used in turbo machinery to transfer torque between two shafts that may experience slight misalignment. This coupling design consists of two sets of thin metallic diaphragms that are bolted together to form a series of corrugations.

There are different types of diaphragm couplings utilized in turbo machinery, mainly categorized as single diaphragm and double/multiple diaphragm couplings. A single diaphragm coupling is a flexible coupling specifically designed to transmit torque between two rotating shafts that may be slightly misaligned. These couplings find applications in various energy equipment such as drilling equipment, turbine drives, compressors, and other turbo machinery. They are constructed using materials such as metal diaphragms, plastic diaphragms, and others, making them suitable for diverse applications across industries such as power, oil and gas, chemicals, transportation, and more.
