Which standard specifies the letters such as IH and ZE in pump types?
Thread Content
I notice that the pump models from many centrifugal pump manufacturers are similar, such as IH pumps. Why is that? Is this model **specified**? I did a search on Baidu and found that it only states compliance with the ISO2858 standard, but this standard only specifies requirements regarding dimensions and design points, without any detailed technical requirements. Is there anyone who knows this? I need some advice.
Pumps do not have a standard model. Due to preconceived notions that favored foreign products, our petrochemical pumps were among the first to adopt pumps from Sulzer and similar brands; generally, centrifugal pumps are of the ZE type, and this naming convention spread throughout China, where it is used everywhere, with some versions being slightly modified
Check the API610 standard; it contains information regarding IH and similar terms
So where is a unified description of this model of pump? Is it the logo of a pump manufacturer abroad?
There shouldn’t be any in API 610; API 610 covers OH, BB, and VS pumps
Based on old models from state-owned enterprises and models from foreign companies
There is no fixed name for it; many types of pumps are based on technology introduced from abroad, and since they are called that in other countries, China adopts the same name for them.
