Sulzer has been chosen to supply both hot and cold molten salts pumps for a major concentrated solar power (CSP) Tower project in China.
Sulzer boasts a long history of delivering molten salt pumps to solar installations worldwide, including recent projects in China. The 100 MW CSP Tower project marks the first of its kind to utilise Sulzer pumps for both hot and cold circuits. Three cold molten salt pumps, fitted with 2.6 MW motors, will extend 18 metres below the base plate into the cold molten salt tank, complemented by two hot pumps. All pumps will be manufactured at Sulzer’s Suzhou plant.
The end-user aimed to achieve several objectives, including sourcing key equipment from international brands, ideally manufactured in China, while remaining cost-effective. Sulzer met all these objectives, with the bare-shaft pump engineering completed in Europe and manufacturing collaboratively undertaken in Belgium and China. Additionally, Sulzer offers a comprehensive support package through its local service centre, streamlining spare parts inventory for the end-user.
