3. Model marking, performance and size
3.1 Carrier marking
Bracket-type high-centre pump (abbreviated as teaching mark) is marked with three parts of the number, the first part indicates the impeller inlet diameter, the first part indicates the impeller outlet diameter. The second part indicates the nominal diameter of the impeller. Marking example,
Suction diameter mm outlet diameter mm, nominal diameter of the system is: 80 50 250
The model writing is composed of two parts: code and mark. IT stands for bracket type centrifugal pump. Model designation method: impeller nominal diameter, outlet diameter, mru
mru diameter, ran
I bracket type centrifugal system
Example:
The suction diameter is B(lumm, the discharge diameter is snmm. The impeller nominal diameter is 25cm. The model of bracket type centrifugal system: TT 8n-50-950
