ISG vertical pipeline pump product overview:
ISG vertical pipeline centrifugal pump is abbreviated as pipeline pump. It is the domestic water pump expert of our factory. The domestic water pump expert selects the domestic excellent hydraulic model, which is often used in: air conditioning water circulation pump, hot water pipeline circulation pump, pipeline booster pump, pipeline pressure pump, cooling. Pumps, chilled water pumps, etc. The performance parameters of the IS type centrifugal pump and the SG type pipeline pump are designed on the basis of the SG pipeline pump, and the vertical hot water pump is derived based on the centrifugal pump of the pipeline according to the use temperature and medium. , stainless steel pipeline pump, explosion-proof centrifugal pump. This series of centrifugal pump products has the advantages of high efficiency, low noise, and reliable performance. This meets the requirements of the latest national machinery department JB/T53058-93 and is designed and manufactured according to the international ISO2858 standard.
