The NL-type mud pump is a single-stage, single-suction vertical centrifugal pump. Its main components include a volute, impeller, pump base, pump casing, support cylinder, motor base, electric motor, etc. The volute, pump base, motor base, and impeller nut are made of cast iron, which has good corrosion resistance and is convenient for the processing technology.

The impeller has three single-circular-arc curved blades. A semi-closed impeller is selected and made of malleable cast iron, so it has high strength and corrosion resistance. It is convenient to process, has good passability, and 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 skeleton oil seals and a shaft sleeve are installed in the pump base to prevent the shaft from being worn and to extend the service life of the shaft. The NL-type mud pump can be used vertically or obliquely, occupying a small area. The volute needs to be submerged in the working medium for operation, which is easy to start without the need for priming water. The direction of rotation should be clockwise when viewed from the rear of the motor. The overall machine lengths are available in various specifications, so that the using units can select them according to local conditions and purposes.

Scope of Application of the NL-type Mud Pump:

The NL-type multi-purpose submersible pump is a single-stage, single-suction centrifugal pump. It is suitable for use in mines, paper making, printing and dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical industry, farms, salt works, iodine works, dyeing and chemical industry, winemaking, food, fertilizers, coking plant separation, construction, marble factories, gold mines, mud, flowing sand, mud ponds, sewage ponds, the suction and delivery of thick slurries and viscous liquids, loading, and sewage operations with suspended substances. It can also be used for drainage in coal mines and for fluids containing mud blocks.

If it is matched with a high-pressure water pump and a water gun to form a hydromechanical earthwork engineering unit, it can be used for land leveling, the dredging and excavation of rivers and ponds, the excavation and transportation of earthworks in small-scale water conservancy projects such as digging, as well as urban air defense projects and the following projects.

In fish farming, it can be used for clearing ponds with water remaining and increasing the oxygen content in fish ponds, etc.
