Abstract
A centrifugal pump sealing structure is provided. In one aspect, one sealing member is provided at a position where leakage paths from a fluid compression space between a middle housing and a cover and an electric component installation space between the middle housing and a lower housing are connected. Then, the two spaces are sealed. The number of sealing members is reduced, so that the internal structure becomes simpler and the assembly of the sealing member becomes easier.
