    Bomba centrfuga, partida radialmente, monocelular, entrada sim-

    ples com a tampa do corpo do lado da chumaceira. O corpo cons-

    titudo por duas peas: a voluta, simples ou dupla, e a tampa. As

    bombas CJG-HT possuem um anel de desgaste no corpo. O impulsor

    do tipo fechado com alhetas dorsais para equilibragem axial.

    O veio suportado no lado do impulsor por uma chumaceira cilndri-

    ca com efeito hidrodinmico e por dois rolamentos radiais justapos-

    tos tipo BG do lado do acoplamento.

    A cmara do empanque possui alhetas de refrigerao por ar, sem

    mecanismos especiais.

    O empanque mecnico normalizado e equilibrado e est localizada

    entre a chumaceira cilndrica do lado do impulsor e a chumaceira

    exterior de rolamentos.

    Centrifugal pump, radially broken, single-stage, simple inlet with

    bodies cover on the bearing bracket side. The body consists on two

    pieces: the volute, simple or double and the casing and cover. CJG-

    HT pumps have a wear ring in the casing. The impeller is a close

    type one with blades in the back for axial balance. The shaft is su-

    pported by the impellers side through a cylindrical bearing bracket

    with hydrodynamic effect and through two BD radial bearings side

    by side on the couplings side.

    The seal chamber has blades of refrigeration by air, without any

    special mechanism.

    Normalized and balanced mechanical seal is situated between the

    cylindrical bearing bracket on the impeller side and the outside

    bearing.

    CJG-HT pump are mainly used for pumping of thermal oil or hot

    water, used especially for medium or big systems, for heating of

    urban spaces or similar and for forced circulation in boilers.

    As bombas CJG-HT so principalmente utilizadas na bombagem

    de leo trmico ou gua quente, especialmente utilizada em siste-

    mas mdios ou de grande escala, no aquecimento urbano ou simi-

    lares e na circulao forada das caldeiras.
