Produce features：

 ʌThe pump consists of the suction casing, the middle section, discharge section, guide vanes and other components, all the parts are fixed by draw-in bolt. The direction of suction port is horizontal, the direction of discharge port is vertical upward;

  ʌThe rotor parts consist of the first impeller, impeller, shaft, shaft sleeve, balance disc and other components, the impellers are installed in series on the shaft, the both end are fixed by large nut, the shaft transfers power to the impeller and make it work, balance disc is used to balance axial force. 

ʌBoth ends of the rotor are supported by bears which are installed in the bearing body, the bearing is lubricated by grease. Some pumps adopt the sliding bearing in both ends, the sliding bearing is lubricated by thin oil.

ʌThe shaft seals in two ends adopt soft packing or mechanical seal. Seal water is introduced into the seal to prevent outside air from entering the pump and a large number of fluid from leaking out of the pump.
