What are the differences between pump models?
Thread Content
Hi Hai Youhao, I have a question: What do the letters SAJ, SCZ, SZA, and IH used in common centrifugal pumps represent? What are the differences? Thank you
They were all raised by the same mother; they are codes for chemical process pumps.
Both CZ and ZA are Sulzer models. Some companies add a single letter before their model numbers after introducing them. So SCZ and SZA came out. SAJ should be part of the same series as IH, right? The CZ, IH, and SAJ sizes comply with the ISO2858 standard, while their technical specifications meet the requirements of ISO5199. ZA OH1 type pump that complies with API standards.
The answer is upstairs. There are now a wide variety of pump models, and it’s not uncommon for one pump to have more than a dozen different names; pump manufacturers play such games for their own benefit.
It depends on the design standards of the pump. Also, the manufacturers deliberately avoid using conventional codes and create their own instead. Confuse people.
Each manufacturer may have its own models, so the original poster need not pay too much attention to the models themselves; rather, the performance parameters of the pump should be the main focus.
I agree with the opinions from Haiyou on floors 4 and 5! It’s easy to slack off in chaotic situations! When water is too clear, there are no fish! I hope everyone will work together to make the chemical industry a cleaner place!
@6th floor~~~ZA belongs to SULZER~~~In a sense, we should be grateful to this Swiss company for helping Chinese industry get rid of IH and IS, allowing it to advance by more than one generation~~~By that logic, when will Flowserve form a joint venture? ~~~~
Many of them are named by the respective manufacturers themselves :)
