National Standard of the People's Republic of China
The model desigeation of reciprocatng pump1Subject content and scope of application
This standard specifies the model desigeation of reciprocatng pump. This standard is applicable to mechanical, gas (steam) driven, hydraulic and manual reciprocating pumps. 2 Model Indication Method
The model of a reciprocating pump consists of capital Chinese Pinyin letters and Arabic numerals, and the indication method is as follows: 0 0 0-0/00.0
Variable model: indicated by numbers 1~9
Special performance: indicated by letters
Rated discharge pressure: indicated by numbers, MPaRated flow: indicated by numbers
GB 11473—89
Structural type: vertical type is L, diaphragm type is M, and other types are not indicated. First characteristic: indicated by letters
Number of couplings (cylinders): indicated by numbers, single coupling (cylinder) is not indicated. Note: ①The first characteristic of the pump refers to the most representative feature of the pump selected from the five categories of pump driving mode, auxiliary medium, structural characteristics, functions and main supporting facilities (see Table 1).
②The content in the dotted box is the reference section (see Chapter 4). Approved by the Ministry of Machinery and Electronics Industry of the People's Republic of China on March 29, 1989 and implemented on January 1, 1990

3.3 The rated flow of multi-cylinder metering pumps is expressed by multiplying the number of cylinders by the rated flow of a single cylinder. The rated flow of other multi-cylinder pumps is expressed by the sum of the rated flows of each cylinder.
3.4 ​​For multi-unit metering pumps, the rated flow and rated discharge pressure of each unit cylinder should be listed separately, and the parameters of each unit should be separated by a withdrawal sign. 4. The last two boxes in the model representation method are reference sections, which can be marked or not. Special performance is represented by the code specified in Table 2. If multiple special properties need to be marked in parallel, they can be marked in the order of letters in Table 2. Special properties
