Abstract

The invention refers to a centrifugal pump of the type comprising a box-like body which defines, inside it, two separate hermetic chambers, a first one for the stator of an electric motor of permanent magnet type, and a second one, of essentially cylindrical extent, for the rotor of the same motor. The box-like body also defines a third chamber, communicating with the second one, for an impeller coaxially connected to the rotor. The pump is characterised in that the rotor and the corresponding impeller can turn on a shaft secured to a support immovably lodged at the bottom of the second chamber and having take-off means which extend as far as the accessible zone of the third chamber. <IMAGE>
