    • PROBLEM TO BE SOLVED: To provide a static seal structure capable of solving at least some of problems of a centrifugal pump with a conventional technology.
      SOLUTION: The present invention relates to a centrifugal pump, a shaft sleeve 60 and a stationary seal member for a static seal used in connection with dynamic seal of the centrifugal pump. The invention relates to the static seal of which clearance can be adjusted while the pump is operated. In particular, the invention discusses the novel structure of such a static seal. The centrifugal pump comprises a pump housing 8, a shaft 6, an impeller, a dynamic seal part 4 and a rotating seal member. In the centrifugal pump, a seal cover 56 has a flexible seal member 77, 92, and an opposing member 68 is arranged associated with the shaft sleeve 60 arranged in the shaft 6.
