Product description

NL series sewage and slurry pump is single-stage, single suction and vertical centrifugal pump. The main parts are pump cochlear shell, pump seat, impeller, motor frame. The pump cochlear, seat, motor frame are made of cast iron, which have the good anti-corrosion function. The impeller is three piece bend impeller and it can also use cast iron in order to have anti-corrosion, easy machining and high efficiency.

No prior water input is needed for starting operation; Light in weight and easy to be removed etc. The impeller is specially designed in blockage free, semi-open. It can make pump discharging sewage and mud with a high capacity.If provided with high pressure pump and water gun, it can make up a hydraulic mechanized earth work unit, used for ground leveling, dredging in rivers and pools, digging, excavation and transportation in small hydraulic engineering, as well as the air defense and underground project in cities.

Application

In rural areas, it is mainly used to handle mud, excrement ,  river water and slurry feedstuff, instead of man labor, and also used for flood and drought control, river mud pumping, manure production, as well as used simply as a traveling fire pump in countryside. 

Used in municipal engineering, infrastructure projects, chemical, printing, dyeing, medicine, shipbuilding, foundry and foodstuff to pump thick and dreggy liquid, paste, sand, flowing silt in rivers, as well as liquid containing mud and stone pieces in coal mines. 

 If provided with high pressure pump and water gun, it can make up a hydraulic mechanized earth work unit, used for ground leveling, dredging in rivers and pools, digging, excavation and transportation in small hydraulic engineering, as well as the air defense and underground project in cities. Used for pond cleaning and oxygen supply in fishery.
