Abstract: 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.

Abstract: The present invention relates to em electric motor assembly (1) comprising a main electric motor (2) and a coupled electric starter motor (3). The electric starter motor (3) may, for instance, be coupled to the rotation axle (4) of the main electric motor (2). In this way, the electric starter motor (3) will be actuated to accelerate the main motor (2) up to a nominal rotation, after which the main motor (2) will be ready to be actuated, and, since it will already be in motion, the current required for accelerating it up to its nominal power will lie within the ranges permitted by the electricity supply companies In this way, it is possible to actuate a motor having a power rating of, for example, 50 HP, with low current peaks.
