The IS series single-stage single suction cantilever centrifugal pump, designed in strict accordance with international standard 1802858 and the latest national standard GB/T 5767, represents a new generation of energy-efficient products. This pump combines the advantages of the original IS type centrifugal water pump, horizontal pump, and cantilever pump, resulting in a more reasonable and reliable design in terms of performance parameters, internal structure, and overall appearance.

The IS series comprises various types of products, including those compliant with the IS02858 standard and those with inlet diameters exceeding 250 (including 250 caliber). With the ability to adjust the impeller and rotation speed, this series offers a total of 170 product variations, catering to the water transportation needs of various industries.

These pumps are suitable for transporting water or liquids with similar physical and chemical properties, including those containing solid particles. Additionally, based on specific requirements, the design and manufacturing can be derived for ISR type hot water pumps and IS type oil pumps. The pump models are applicable for medium temperatures up to 80°C, while ISR pumps are suitable for medium temperatures below 100°C, and ISY pumps are designed for the transportation of gasoline, diesel oil, and light oil. The flow rate of this series ranges from 3.4 to 1440m³/h, with a head range of 3.7 to 133m. The pumps can be categorized into normal speed (2900rpm) and reduced speed (1450rpm) types based on operating speed.
