LW series of vertical sewage pump is widely used in urban water supply and drainage, industrial and mining enterprises, commercial and domestic sewage, mud, manure, ash, pulp and other transportation and emissions. Can also be used as circulating pump, farm irrigation pumps. Transmission medium temperature is not more than 80 ℃, impurity content (weight ratio) does not exceed 25%, PH = 4 ~ 10, through the solid particle diameter of 15 ~ 110mm. LW vertical sewage pump mainly by the pump, impeller, pump cover, shaft, base, bearing, motor frame and other components. The pump is a single-suction volute, the impeller adopts single (double) flow channel or single (double) blade structure, without plugging hydraulic design, with good performance, stable operation, small vibration, high reliability, easy installation and convenient operation Can be automatically controlled. Motor and LW vertical sewage pump with direct connection and stratified installation of two types, both pump body and inlet pipe holes for the discharge of dirt. Liquid axial inhalation, horizontal discharge. The discharge diameter of the pump in the range of 65 ~ 350mm, with elbow base, the upper bearing grease lubrication, the lower bearing with thin oil lubrication, shaft seal for the mechanical seal; discharge diameter of 350mm above the pump, the use of straight pipe base, bearing Grease lubrication, shaft seal is wear-resistant PTFE packing. The pump is driven directly by the motor via a flexible coupling. From the motor end, the LW vertical drain pump rotates clockwise.
