Application of hydraulic high-pressure water pump in seawater desalination equipment-INDUSTRY NEWS-Medium pump fluid

Hydraulic high-pressure water pump is a key component in seawater desalination equipment, especially playing an important role in reverse osmosis seawater desalination systems. This pump is responsible for providing the necessary high pressure to push seawater through a semi permeable membrane, thereby achieving the desalination process.

Recent developments include the VMHP membrane seawater desalination high-pressure pump developed by China International Capital Environmental Protection Corporation, which has been applied in the seawater desalination industry and has participated in the construction of seawater desalination projects in Tianjin, Longkou and other cities. In addition, Beijing University of Technology has also achieved significant results in the key technology and industrialization of seawater hydraulic pumps. They have successfully developed multiple highly reliable seawater hydraulic pump prototypes, which are suitable for various fields such as reverse osmosis seawater desalination systems, underwater operation tool systems, and high-pressure fine water mist fire suppression systems.

Danfoss also offers high-energy efficiency pumps designed specifically for seawater desalination, which are suitable for various seawater desalination applications on land, near shore, and at sea, and have high efficiency and low lifecycle costs.

In practical applications, some new high-pressure booster pumps for seawater desalination have been industrialized and validated in the 5000 ton/day reverse osmosis unit of Zhejiang Zhoushan Liuheng Water Company, proving their high efficiency and stability. These pumps not only meet the wear and corrosion resistance requirements of seawater desalination conditions, but also have the characteristics of high efficiency, simplicity, and easy maintenance.

These developments indicate that the application of hydraulic high-pressure water pumps in seawater desalination equipment is constantly advancing, not only improving equipment efficiency and reliability, but also helping to reduce operating costs and promote the development of seawater desalination technology.
