What do ZA, 150, and 4630 mean respectively?
With Baidu, there’s nothing you can think of that it can’t search for
Many explanations on Baidu are also problematic; it’s better to consult the manufacturer for more reliable information!
Different manufacturers often have their own specific numbering systems, which can be problematic
This is the internal naming convention of the pump manufacturer; consult the company’s technical staff.
