(57) The present invention comprises a pump (10, 110) having a casing (14, 114) with at
least one first hermetically sealed chamber (19, 119) and at least one second chamber
(17, 117) adjacent to said first chamber, defining a passageway (18, 118) for fluids
and having an inlet (15, 115) and an outlet (16, 116) for the fluids. The stator (12,
112) is provided in this first chamber (19, 119). In addition, a rotor-turbine assembly
(11, 111) is induced by the stator (12, 112) to drive a fluid from the inlet (15,
115) to the outlet (16, 116), the rotor and the turbine being integral and wholly
located in the second chamber (17, 117). In a preferred embodiment; a fluid course
between the opening of outlet (115) and fluid passage (118), in portion (119a) of
first chamber (119), is provided with filtration zone (120) suitable for filtration
of a fluid to be impelled by the pump.
