What is the difference between Sulzer’s centrifugal pumps in the CZ and ZA series?
Thread Content
RT, I don’t understand why there’s a Z series if a CZ is also needed
Personally, I think it’s the difference in support forms, that is, the difference between OH1 and OH2
ZE is a central support, while ZA and CZ are both bottom corner supports. I think the Z series meets the API requirements, whereas CZ does not; I’m not sure if this is correct
CZ pumps follow the ISO5199 standard, while Z-series pumps adhere to the API standard
