High pressure circulation pumps are used to transport high-temperature and high pressure hot water in power plants, serving as circulation pumps. They are also suitable for hot water circulation in pipeline systems or closed loops in metallurgical, chemical, and waste heat recovery systems. The dataset includes primary raw materials, auxiliary materials, energy inputs, atmospheric emissions, and waste generated during the production process. Infrastructure such as production equipment and factory construction is excluded from the system boundary of the dataset. The life cycle inventory is compiled from data collected from multiple sources. The manufacturing process of high pressure circulation pumps includes raw material preparation, component machining, product assembly, painting, packaging, and other related operations.
