The NWL pump is suitable for mining, papermaking, printing and dyeing, environmental protection, municipal construction, chemical industry, food, asbestos tile factories, etc., to transport ore liquid, river mud, feces, and slurry feed in Nongcun. Dirty liquids, pastes, and slurries such as fine pulp in paper mills, riverbed water, asbestos tile pulp, etc. are products that the clean water pump can't control.

 

       The pump occupies a small area, simple structure, easy to move, submerged operation, no need to irrigate water, low cost, high cost performance, economical and practical.

 

       The improved NWLX pump is an improvement on the original common type. The submersible uses high wear resistance and corrosion resistance, fluorine rubber bearings, and eliminates the previously used ball bearings. The oil seal is no longer used as a water seal under the liquid. A positioning sleeve is designed in the middle of the long shaft to enhance the stability of the shaft during high-speed rotation. Double rolling bearings are designed under the motor seat, and the lubricating hole is used to add lubricating oil in time. The upper end of the shaft is designed with a locking device to prevent the rotor from falling down.
