NL mud pump

NL series mud pump is a single-stage single-suction vertical centrifugal pump. The main components are volute, impeller, pump seat, pump casing, support cylinder, motor seat and motor. The volute, pump seat, motor seat and impeller nut are cast iron casting, good corrosion resistance and corrosion resistance, and the processing technology is convenient. 
The impeller is a three-piece single-chord curved blade. The semi-closed impeller is used, and the malleable cast iron is used, so the strength is high and corrosion resistance; the processing is convenient, the passability is good, and the efficiency is high. 
    In order to reduce the weight and reduce the amount of turning, the pump shaft is made of high quality carbon steel cold drawn steel. 
    Four skeleton oil seals and bushings are installed in the pump seat to prevent shaft wear and extend the service life of the shaft. 
    NL series sewage cement pump can be used vertically or tilted. It has a small footprint. The volute needs to be buried in the working medium to work easily. It does not need to be watered. The direction of rotation should be clockwise from the rear of the motor. 
    The length of the main unit is available in various specifications so that the unit can be selected according to the application.

Model meaning: 

The main purpose: 

     1. NL series multi-purpose liquid submerged mud pump is a single-stage single-suction centrifugal pump used in mining, paper making, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical, farm, salt field, iodine field, dyeing , brewing, food, fertilizer, coking plant, construction, marble plant, gold mine, mud, quicksand, mud pond, sewage pond, sewage liquid to send thick slurry thick liquid, charging and suspended materials sewage operation, can also be used for coal mine drainage And fluids containing mud. 
2. If combined with high-pressure water pump and water gun, the hydraulic mechanized earthwork engineering unit can be used for land leveling, excavation and transportation of small water conservancy projects such as dredging and ponding of rivers and ponds, and urban air defense works. engineering. 
3. Fish farming is used to bring water to clear ponds, fish ponds to increase oxygen, etc.
