Abstract

Unidad de bomba centrífuga que presenta un motor envainado provisto con una vaina tubular acopada de entrehierro, que obtura el bobinado del motor conrespecto a la cámara de rotor. El motor está dispuesto dentro de una carcasa de motor, a la cual seacopla axialmente una carcasa de bomba en la cual gira unrodete impulsado por el motor. En la zona comprendida entre la vaina tubular acopada y la carcasa de bomba se han previsto medios de obturacion. Entre lacarcasa de motor y la carcasa de bombas e ha previsto un adaptador, habiéndose dispuesto medios obturacion entre el adaptador y carcasa de bomba, como tambiénentre la vaina tubular acopada y el adaptador. Un motor, como es en sí conocido de las bombas de circulacion de calefaccion,puede s er aplicado con el auxiliode este adaptador con una carcasa de bomba periféricamente sustancialmente más grande y en consecuencia también con un rodete más grande.Centrifugal pump unit that features a sheathed motor provided with a tubular sheath coupled with air gap, which seals the motor winding with respect to the rotor chamber. The motor is arranged inside a motor housing, to which a pump housing is axially coupled in which a motor-driven wheel rotates. Sealing means are provided in the area between the coupled tubular sheath and the pump housing. An adapter is provided between the motor housing and the pump casing, with sealing means being arranged between the adapter and the pump housing, as well as between the coupled tubular sheath and the adapter. An engine, as is known per se of the circulation circulating pumps, can be applied with the aid of this adapter with a substantially larger peripherally pump housing and consequently also with a larger impeller.
