This standard specifies the types and basic parameters of multistage clean water centrifugal pumps. This standard applies to pumps that transport clean water or other liquids with physical and chemical properties similar to water. The temperature of the transported liquid is generally not higher than 80℃, and the temperature of the boiler feed water is not higher than 110℃.

Type and basic parameters
Structural type
The pump is multistage horizontal. The impeller is single suction (or the first stage impeller is double suction), and the casing is segmented. 3.2 Basic parameters
3.2.1 The basic parameters of the pump shall comply with the provisions of the table, and the values ​​listed in the table are the performance at the specified point. The performance operating range of the pump is shown in the figure. 3.2.2 The efficiency of the pump shall comply with the provisions of GB/T13007. 3.2.3 The NPSH of the pump shall comply with the provisions of GB/T13006. 3.2.4 The performance inspection and deviation of the pump shall comply with the provisions of GB5659. 3.3 Model indication method
