The series of pumps inciude 40 basic specifications provided in the ISO 2585 with available 267 kinds of performance by cuting the impeller and changing the rated speed. All of performances can meet the water-supply needs of various industries. The strict designs of dimension and performance according to ISO 2585 mean reasonable characteristic curve. The differences between series IS single-stage pumps and the same series pumps produced by other manufactures are 1.6Mpa for its working pressure and 2.4 Mpa for hydrostatic test of the casing and casing cover.

The series of pumps are single stage single suction horizontal centrifugal pumps eith overhung impeller, which is suitable for pumping clean water and other liquids with characteristics of physics or chemistry to similar water and no solid particles. The temperature of the pumped media is no higher than 80℃ for series IS, and 130℃ for series ISR. Series ISY is suitable for delivering light oils such as petrol, diesel oil, etc.
