The forthcoming

The "Energy recovery device General Technology Criterion" which is drafted by Nanfang Pump Co.,Ltd on December 31st,2014 will be put into implementation from August 1st,2014.

As one of the three key device of seawater reverse osmosis, energy recovery device was the only one that depends on import.It is mainly applied to domestic large-scale projects. CNP successfully let the energy recovery device be localization.It is also the second research subject of state science and technology support program assigned to CNP.

The criterion mainly stipulates the classification, type, technical requirements, test methods, inspection rule of energy recovery device.

CNP, a green water expert beside you.

CNP integrates the advanced R&D technologies from Europe and America, with the most advanced industrial design concept in Western Europe, with the production experience of modern industrial clusters in North America, with the most efficient and energy-saving product structure research in Hangzhou, China.

With the application of information technology, CNP has built its own smart factory, taking the lead in the introduction of SAP resource management system, becoming one of the key units of the key construction project of  "machine substitution" in Hangzhou, with the whole process of production information monitoring and tracking, applying laser welding technology to the manufacturing process of robot pump spare parts in depth, using progressive die technology to ensure the quality of the whole process of the parts, all of which greatly reduce the production and manufacturing cycle, provide an intelligent production and manufacturing basis for the pump production.

CNP was recognized as state-certified enterprise technology center in 2016. It is the highest evaluation level for technology center in China. Besides, CNP has been carrying some technical courses in 11/12/13th National Five-Year Plan.

CNP uses digital integrated intelligent control technology to create domestic advanced M2M mode, intelligent control technology.

It includes intelligent current stabilization system, intelligent vacuum suppression system, intelligent auxiliary control monitoring system, intelligent non-negative pressure full frequency control system and intelligent water hammer two-way elimination system.
