1. ISGD series low-speed centrifugal pump is designed on the basis of ISG vertical centrifugal pump uniting low speed motor, which greatly decrease the operating noise and redouble prolong damageable part's useful life, it is most suitable for air-condition cycling and all kind of cycling's end super charging creatively design vertical structure makes it cover less area and less space, also used more convenient.
2. ISGD series centrifugal pump with low speed is designed on the basis of ISG series, also referring to IS centrifugal pump's performance parameter and according to pipeline centrifugal pump's special characteristics. They are made and designed strictly complying with international standard ISO2858.
3. The products which have many advantages such as high-effective, reliable specification adopt hard hitting hydraulic model provided by pump's experts. Some of them gaining good recognition of customers from home and abroad are exported.
