As the global energy structure accelerates its transformation, the upgrading of thermal power, the expansion of nuclear power safety, and the large-scale development of photovoltaics have become the main themes of the industry. As the core supporting equipment of power production, the performance of the vacuum pump system directly affects unit efficiency, environmental protection levels, and operational safety. According to the QYResearch report, the global vacuum pump market size reached US$14.69 billion in 2024 and is expected to increase to US$23.15 billion by 2031, with a compound annual growth rate of 6.8%. The power industry has become a core demand scenario.

In this context, Edwards, a global leader with 95 years of experience in vacuum technology, has achieved extensive implementation in the global power industry with its full range of liquid ring vacuum pump product matrices and customized solutions. With the three core advantages of "high efficiency and energy saving + stability and reliability + multi-scenario adaptation," it provides hard-core support for power enterprises to reduce costs and increase efficiency, leading the innovation of industrial vacuum technology.

1. Industry Pain Points: Why Traditional Equipment Struggles

In power projects such as thermal, nuclear, and solar power plants, core links such as condenser air extraction, water chamber vacuuming, and flue gas treatment place strict requirements on equipment. However, traditional systems face three major bottlenecks:

• Efficiency Bottleneck: Limited pumping capacity makes it difficult to maintain high vacuum in condensers, leading to increased back pressure in steam turbines and higher coal consumption.
• Poor Adaptability: In nuclear or geothermal plants, media contain corrosive components. Traditional equipment is prone to wear and corrosion, while dusty conditions lead to frequent clogging.
• Compliance Issues: Many devices fail to meet HEI global industry standards, consuming excessive sealing water and failing to meet modern carbon reduction requirements.
