ABSTRACT:
A centrifugal pump has a casing with a cylindrical shell surrounding a volute-type inner section which is formed with a hollow radial extension for admission of fluid into a nipple of the shell. The extension forms part of or constitutes a separable sealing device between a passage of the inner section and a passage of the shell. The inner section is suspended in the shell by one or more pipes which are coaxial with the rotor and/or by one or more projections which extend radially from the inner section and abut against the internal surface of the shell or extend into recesses provided therefor in the internal surface of the shell.
