Jiangsu Haifa Machinery Manufacturing Co., Ltd.

In 2026, China independently developed the S4000 tethered airborne wind energy generation system, completing full-process validation tests covering ascent, station-keeping, power generation, and recovery at an altitude of 4,000 meters, marking the official transition of high-altitude wind energy systems from technological R&D to engineering deployment. The S4000 is equipped with a helium-based floating platform, lightweight power generation modules, ducted ejector diffusion, and kilometer-level medium-voltage power transmission systems. The test data will provide critical support for the subsequent development of the S6000-5MW high-power product. The development of the high-altitude wind energy industry will drive the deployment of diverse application scenarios including green hydrogen, energy storage, Power-to-X, island off-grid power supply, mining area power supply, and-carbon industrial parks, generating substantial demand for new energy equipment. Green hydrogen production, energy storage thermal management, medium circulation cooling, water treatment, and new energy chemical facilities all rely on high-reliability fluid transfer core components such as chemical process pumps, imposing stringent requirements on the continuous operation performance of corrosion-resistant centrifugal pumps and leak-free magnetic drive pumps. In response to the new energy supporting market derived from high-altitude wind, Jiangsu Haifa Machinery Manufacturing Co., Ltd.www.jslgpump.com), specializing in the R&D and manufacturing of API series pumps, offers API 610 process pumps BB5 high-pressure multistage pumps, API 685 magnetic drive pumps, high-temperature high-pressure chemical pumps, and special pumps for new energy applications. Targeting emerging operating conditions in green hydrogen, energy storage, water treatment, and new energy chemicals, the company provides professional pump selection and engineered fluid transfer solutions for complex media, the long-cycle, high-reliability operational requirements of new energy projects and contributing to the localization of supporting equipment for the high-altitude wind power industry chain.
