Type IH pump is single-stage and single-suction (axial suction) corrosion resistant centrifugal pump, which is suitable for pumping corrosive liquid without solid particles or other liquid whose consistency is similar to that of clean water. The temperature of medium is -20～105℃, if necessary, cooling measure can be taken to reach a higher temperature. It applies to petroleum, chemical, metallurgical, power, paper making，foodstuff, pharmaceutical, and synthetic fiber industry, etc. 

IS Series are single-stage and single-suction centrifugal pumps. They are intended for supplying clean water or liquid with similar physical and chemical properties as that of water at a temperature up to 80℃. The main fields of application of IS pump are in factories, cities, farm irrigation, etc. Type ISR pump is a product of high efficiency and low consumption. The performance parameters of ISR pump are equivalent to that of IS type pumps. It is suitable for transporting liquid with temperature less than 130℃.
