Conveying element e.g. magnetic drive pump has connecting bore which is correspondingly connected with through-hole of shaft

摘要

The conveying element has a shaft that is provided with a through-hole (26) and a bearing. An inner magnetic rotor (17) is arranged on the shaft. A channel system (41) is provided in the inner magnetic rotor. A connecting hole (42) is correspondingly connected with the through-hole of shaft. A gap (19) is formed between the bearing housing and inner magnetic rotor. A cooling gap (24) is formed between the shroud (22) and inner magnetic rotor.
