8In spite of the same specification, the pump's performance vary with the outer diameter of the impeller.(Indicated with the block letters A, B and C in the end of the designation of the type.)
8The pump is simple in structure, reliable in preoformance, samll in size, low in power consumption, convenient in maintenance and of good caviation proof.
8XA has 60 specifications with the shaft in four sizes, suitable for various handling duties. For the pump with a same specification, the components, such as shaft, bearings,shaft sleeve, shaft seal and the fasteners of impellers are exchangebable.In addition, only five types of bearing brackets are applied to the whole series.
