Centrifugal pump with fixed axis

摘要

The pump has a fixed shaft (3) on which a permanent magnet pump impeller is rotatably supported, where the impeller cooperates with an electronically commutated stator. The shaft is fixed with a pump housing part of a multi-part pump housing and forms a symmetry axis with respect to an inner wall region of the part. The part is formed as a pump head (2) and includes or is attached to a suction connector (6). The shaft is connected with an mounting pin (22) of the part, in a form-fit manner. An independent claim is also included for a method for manufacturing a pump head of a centrifugal pump.
