A pump wherein the parts of the casing forming, together with the partitions and sealing members, chambers for the accommodation of impellers mounted in a counteropposed manner on a shaft, are interconnected in the plane perpendicular to the rotation axis of the impellers by a clamp. The clamp consists of two parts with the joining plane passing through the rotation axis of the impellers and the clamp has circular collars at the edges, the collars entering circular recesses provided in flanges located on the opposite sides of the casing parts. The clamp is adapted for compressing the sealing members while the clamp parts are being brought together.
