1、 Product introduction

XA is used for handling clear water or the liquids similar to the water physically and chemically finding the applications for water feed and supply service in mine, plants and towns, air-conditioning, extinguishing and irrigation.

In spite of the same specification, the pump's performances vary with the diameter of the impeller. (Indicated with the block letters A,B and C in the end of the designation of the type. )

The pump is simple in structure, reliable in performances, small in size, low in power consumption, convenient in maintenance and of good cavitation proof.

XA has 42 models 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 impeller are exchangeable. In addition, only five types of bearing brackets are applied to the whole series.

 

2、Description of structure

XA is a back-open type. The pump cover and the impeller can be dismantled without taking out both the suction and discharge piping. In the bearing bracket, there are two ball bearings which are lubricated with oils or grease. The pump is driven through the flexible couplings by the motor. Volute casing, feet, and both suction and discharge flanges are cast integrally in one piece.
