1 Scope

GB/T 13008-2010 is the Chinese national standard on technical specification for mixed and axial flow pumps, in the field of fluid systems and general-purpose components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 26 September 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2011. Classification: ICS 23.080, CCS J71. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the mixed-flow pump, axial flow pump (hereinafter referred to as the pump) ordering conditions, technical requirements, the factory inspection and testing requirements and performance test Inspection rules. This standard applies to transport water or physical and chemical properties similar to liquid water and the pump delivery seawater pump. Delivery temperature of the liquid Not more than 50 °C. When present conflict between the technical requirements of more than one file, the following order shall determine the suitability of each file.

b) the data table (see Appendix A);

c) of this standard;

d) orders other criteria mentioned.
