product overview
The ISG series single-stage single suction vertical centrifugal pump is a second-generation high-efficiency and energy-saving product designed by our company based on the performance parameters specified in international ISO2858 and national standard JB/T6878.2-93, combined with our years of production experience. It is an ideal product to replace conventional pumps such as SG type pipeline centrifugal pumps, IS type centrifugal pumps, and D-type multi-stage centrifugal pumps

Product Features
The pump is a vertical structure with the same inlet and outlet diameters and located on the same centerline. It can be installed in pipelines like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. If a protective cover is added, it can be used outdoors. The impeller is directly installed on the extended shaft of the motor, with a short axial dimension and a reasonable configuration of pump and motor bearings, which can effectively balance the radial and axial loads generated by the pump operation, ensuring smooth pump operation and low vibration noise. Installing and repairing instant noodles does not require dismantling the piping system. Simply remove the pump coupling nut to extract all rotor components. Pumps can be operated in series or parallel according to the requirements of flow rate and head. Vertical and horizontal installation of pumps can be adopted according to the requirements of pipeline layout. Series flow range of 1.5-1600m3/h, head range of 5-125m, available in various specifications such as basic type, diversion type, cutting type, etc

application
ISG vertical pipeline centrifugal pump is used for transporting clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire protection pressurization, long-distance transportation, HVAC refrigeration cycle, cold and warm water cycle pressurization, and equipment matching. The operating temperature is less than 80 ℃.
