摘要： The chucking device for electric cables for submersible pumps comprises clamping means (18) of the electric cables (15a) suitable to be constrained to the body of a pump or the like through coupling means (17). The clamping means (18) comprise a connector (25) suitable to be con- strained to the coupling means (17) and a tear-resistant sleeve shaped clamping member (26), suitable to house a portion of at least one electric cable (15a) and to be brought by the connector laterally to a respective final length (31), so that the tear-resistant sleeve (26) is suitable to exercise with a respective edge of the final length (31) a compression onto the electric cable (15a) such to prevent the sliding through the sleeve (26) as reaction of the connector (25) to a traction acting on the electric cable (15a).

摘要： The centrifugal pump stage comprises an impeller unit (10) having an axial hub (1 1 ) suitable to be mounted of the motor shaft (2) of the pump. A diffuser unit (20) extends at a first face of the impeller unit (10) and an aspiration lid (30) associated with the diffuser unit (20) extends at a second face of the impeller unit (10). The impeller unit (10) is supported floating at the diffuser unit (20) between a first position and a second position in which the axial hub (1 1 ) is abutting against respective locking rings (4) stiffly associated with the motor shaft (2) of the centrifugal pump, in order to be rotatable together with the same shaft (2).
