Document Type and Number:
Japanese Patent JP2535004
Kind Code:
B2
Abstract:
A centrifugal pump of the magneto coupling type in which an isolation shell separates the pump side from the driver side includes an auxiliary impeller arranged additionally to the pump impeller proper. This allows a decreasing of the pressure in the spaces at the reverse side of the pump impeller and thus a balancing of the thrust forces. This effect can be controlled by control means located in the casing at the outer end of the feeding channels of the auxiliary impeller. This allows the provision of a pump of a simple design in which e.g. the isolation shell can be made with an extremely small wall thickness and in which an open or closed pump impeller can be supported without any thrust generated difficulties.
