1.submerged pumpOverview：
    NPL centrifugal submersible mud and sand pump and NPW centrifugal horizontal mud and sand pump are new generation pump sister products developed based on the introduction of advanced technologies at home and abroad, combined with the characteristics of pump use at home and abroad. They have significant energy-saving effects, anti entanglement, and no blockage, and have unique effects in discharging particles and long fiber garbage.
    NPL and NPW pumps use unique impeller structures to effectively transport liquids containing solids and chemical fibers. Compared with traditional impellers, this pump impeller adopts a single channel open or double channel design, which is similar to a curved pipe with the same cross-sectional size and has very good overcurrent performance. Coupled with a reasonable volute chamber, this pump has the characteristics of high efficiency and good overcurrent effect. The impeller has undergone dynamic balance testing, which ensures that the pump operates without vibration.
    The NPL pump has no bottom valve, no need to inject water when starting, automatic water withdrawal when stopping, and does not freeze the pipeline during winter operation. It is easier to operate and maintain than the slurry pump and can also replace the slurry pump for operation. The hydraulic performance is advanced and mature, and all performance indicators of the product have been tested to meet relevant standards. After its launch on the market, the product has been welcomed and praised by a large number of users for its unique efficacy, reliable performance, and stable quality.
