Water pump NLT

with electric motorself-primingcentrifugal

The pump is of vertical multi-stage centrifugal pump, the lower part of pump base is pulling-out cartridge structure which makes dismantling and maintenance easily; The angle between the pump outlet and inlet can be made into multiple angles including 90°,180°and 270°for shifting; In order to make the pump have better anti-cavitation performance, the first stage of impeller is specially designed to combine used with inducer or adopt double suction structure. On the basis of meeting performance requirements and enough rigidity, axial guide vane is used to reduce the pump’s radial size; It is recommended to set thrust bearing on the pump, and to use flexible coupling to connect pump and motor to make pump centering and erection easily. Mechanical seal is adopted as the shaft seal of the pump. According to different requirements from end-users, the position of pump inlet should be put at the lower or upper part of the base.
