Product Overview 
 ISG Series single-stage single-suction vertical centrifugal pump is a reference to the provisions of the international ISO2858 and national standard JB/T6878.2-93 performance parameters, combined with the company many years of experience in production and design of the second generation of energy efficient products, alternative SG type pipe centrifugal pump, IS centrifugal pump, D-type multi-stage centrifugal pumps and other conventional pumps ideal product 

 Features 
 Pump for the vertical structure, import and export of the same caliber, and in the same center line as the valve installed in the piping into the compact appearance, small footprint, the building into low, such as coupled with the protective cover can placed in outdoor use. Impeller mounted directly on the longer axis of the motor, short axial dimension, the pump and motor bearing configuration is reasonable, can effectively balance the radial and axial loads of pump operation, thus ensuring the smooth operation of the pump, low vibration and noise . Installation and maintenance of instant noodles, no need to open the pipeline system, remove the pump conjoined nut to be pulled out all the rotor components. According to the requirements of the flow and head need to use pumps in series and parallel operation mode. According to the vertical and horizontal piping arrangements require the use of pump installation. Series flow range of 1.5 ~ 1600m3 / h, the lift range 5 ~ 125m, the basic type, shunt type, cut type, such as a variety of specifications 

 Product Use 
 ISG vertical pipeline centrifugal pumps for the transport of water and physical and chemical properties similar to water and other liquids used for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire booster, long distance transportation, HVAC refrigeration cycle, heating and water circulation booster and equipment for the use of temperature <80 ° C.
