The present invention relates to a centrifugal pump and a static seal of the dynamic sealing thereof. The invention especially relates to modifying the attachment of said static seal and a seal cover acting as a counter ring thereof in such a way that, for example, when the static seal wears, the clearance thereof can be adjusted without a need to stop the pump. A characteristic feature of a centrifugal pump in accordance with the invention, comprising, among other things, a pump housing ( 72 ), a shaft ( 12 ), an impeller arranged on the shaft and a dynamic seal ( 30, 32 ) arranged in connection with the shaft ( 12 ), and a static seal arranged in connection with the shaft ( 12 ) behind the dynamic seal as seen from the impeller, said static seal comprising a flexible seal means ( 50 ) on the shaft ( 12 ) and a stationary counter ring thereof, is that a seal cover ( 62 ) including a stationary counter ring ( 60 ) is adjustable in the axial direction of the pump.
