Interpretation of magnetic pump models

65CQ-25PB, could some expert explain the meaning of each symbol?
This post was last edited by foam_ZPTK on 2018-3-1 at 16:34: 65 – Pump inlet diameter (mm); CQ – Magnetic drive pump; 25 – Operating head (m). PB may refer to the material as well as whether the pump is explosion-proof or not
Adding to what was said above: P generally stands for 304; B means explosion-proof. This designation is not standardized either – it’s determined by each manufacturer, so the manufacturer’s specification should be taken as the standard.
