Abstract

A submersible centrifugal pump 1 comprises a containment jacket 2, an intake body 5 and a delivery body 4 welded to the jacket 2 containing the hydraulic stages 10, each consisting of an impeller 11 and a diffuser 12. The stages 10 are compacted in the jacket between the delivery body 4 and the intake body 5 by clamping means which comprise at least one screw 29 or one tie rod. There is also an easily removable non-return valve 22 located in the delivery body 4.
