Explanation of pump types
Thread Content
I saw mentions of SH pumps and IS pumps in an article. May I ask everyone: what type of pumps are SH pumps and IS pumps? Where do SH and IS come from then?
SH refers to a double-suction centrifugal pump, while IS denotes an international standard centrifugal pump for clean water; you can tell what they mean by looking at their pinyin and English letters.
Sh-- is the code for domestic double (Pinyin: Sh) suction pumps, while IS-- (in English) is the code for single-stage, single-suction cantilever centrifugal clean water pumps designed in China in accordance with international standards!
