Abstract

The centrifugal pump has a housing (11) with fluid inlet (111) and outlet (112) openings. There is a casing (12) behind the housing and connected to a motor (14) with a shaft (121) surrounded by a bearing (122) with an inner helical fluid channel. A magnet casing is provided between the bearing and casing, and between the bearing and casing is a peripheral channel and rib (128) together with the helical channel in the bearing.
