Overview of NL sewage mud pump

The NL sewage cement slurry pump is a single-stage single suction vertical centrifugal pump, consisting of main components such as volute, impeller, pump seat, pump casing, support cylinder, motor seat, and electric motor. The snail shell, pump seat, motor seat, and impeller nut are cast from pig iron, with good corrosion resistance and convenient processing technology. The impeller consists of three single chord curved blades, which are semi enclosed and made of malleable cast iron, resulting in high strength and corrosion resistance; Easy processing, good passability, and high efficiency. In order to reduce weight and cutting volume, the pump shaft is made of high-quality carbon steel cold drawn round steel. The mud pump seat is equipped with four skeleton oil seals and shaft sleeves to prevent shaft wear and extend the service life of the shaft. This mud pump can be used vertically or obliquely, with a small footprint. The volute shell needs to be buried in the working medium for easy start-up and does not require water intake. The rotation direction should be clockwise when viewed from the tail of the motor. There are various specifications for the length of the switchboard, so that users can choose according to their specific needs.

Main uses of NL sewage cement slurry pump

① NL type mud pump is used in mining, papermaking, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical industry, farms, salt fields, iodine fields, dyeing, brewing, food, fertilizer, coking plants, construction, marble plants, gold mines, mud, quicksand, mud ponds, sewage ponds, polluted liquids for conveying and absorbing thick slurry, loading and suspended solids in sewage operations. It can also be used for coal mine drainage and fluids containing mud blocks.

② If the mud pump is combined with high-pressure water pumps and water guns to form a hydraulic mechanized earthwork unit, it can be used for excavation and transportation of small water conservancy projects such as land leveling, dredging and chiseling of rivers and ponds, as well as urban air defense projects.

③ Fish farming is used for carrying water to clear ponds, increasing oxygen in fish ponds, etc.
