Product overview
NL sewage mud pump is a single-stage single suction vertical centrifugal pump. Its main components are volute, impeller, pump seat, pump shell, support cylinder, motor base, motor, etc. The volute, pump seat, motor seat and impeller nut are cast by pig iron with good corrosion resistance and corrosion resistance, and the processing technology is convenient.
Impeller for three single chord curved blade, semi closed impeller, and the use of malleable iron, so high strength, corrosion resistance; easy processing, good trafficability, high efficiency.
In order to reduce the weight and the amount of turning, the pump shaft is made of high quality carbon steel cold drawn round steel.
Four frame oil seals and shaft sleeves are installed in the pump seat to prevent shaft wear and prolong the service life of the shaft.
The pump can be used vertically or obliquely, occupying a small area. The volute needs to be buried in the working medium. It is easy to start. It does not need bow I water. The rotation direction should be clockwise from the end of the motor.
There are various specifications of switchboard length, so that the user can choose according to the use and local conditions.

Head NL series sewage cement slurry pump main uses:
1. NL type multi-purpose submerged pump is a single-stage single suction centrifugal pump, which is used in mining, papermaking, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical industry, farm, salt field, iodine field, dyeing and chemical industry, wine making, food, chemical fertilizer, coking, dressing plant, construction, marble factory, gold mine, mud, quicksand, mud pond, sewage pond, muddy liquid to transport and absorb thick liquid, loading and suspension The sewage operation of floating material can also be used as mine drainage and fluid containing mud.
2. If combined with high-pressure water pump and water gun to form hydraulic mechanization earthwork unit, it can be used for the excavation and transportation of small water conservancy projects, such as land leveling, river channel and pond dredging and digging, as well as urban air defense engineering and underground engineering.
3. Fish culture is used to clean ponds with water and increase oxygen in fish ponds.
