Product Description: ISG/ISW series single stage single suction pipeline centrifugal pump are designed by scientific and technical personnel of our company and domestic water pump experts, which select the domestic excellent hydraulic model, adopt the performance parameter of the centrifugal pump of Model IS. Besides, according to different using temperature and medium, we develop pumps applicable for hot water, high temperature the corrosive environment, oil transporting on the basis of Model ALG. The series of products have the characters of saving power, low noise, reliable performance, etc. They are comply with the latest standard of national mechanical department JB/T53058-93, and are designed and made in accordance with the international ISO2858 standard. Working Conditions: 1, Suction pressure≤1.0MPa, or the maximum working pressure of pump system≤1.6MPa, i.e. pump suction pressure + pump head ≤1.6MPa, and pump static test pressure is 2.5MPa.Please specify the system working pressure when placing an order. If the working pressure of pump system is to be greater than 1.6MPa, then it should be specified separately when placing an order for our convenience to use cast steel material for wetted parts and joints. 2, Ambient temperature<40°C,relative humidity<95%. 3, The volumetric content of solid particles in the medium to be handled shall not exceed the 0.1% of unit volume, and the granularity shall be<0.2mm. Remark: To handle medium containing small particles, please specify when placing an order for our convenience to use wear resisting mechanical seal.
