I. Product Overview:

NL Type sludge pump main components include volute, impeller, pump base, pump housing, support tube, motor bracket, electric motor, etc. The volute, pump base, motor bracket, and impeller nut are made of cast iron with good corrosion resistance and are easy to process.

The impeller features three single-arc bent blades, utilizes a semi-closed impeller design, and is made of forgable cast iron for high strength and corrosion resistance; it is easy to machine, offers good flow passage, and is highly efficient.

2. To reduce weight and minimize machining, the pump shaft is made from high-quality carbon steel cold-drawn round steel.

3. The pump base is equipped with four skeleton oil seals and shaft sleeves to prevent shaft wear and extend the shaft's service life.

4. The NL type sludge pump can be used vertically or inclined, occupying minimal floor space. The volute must be submerged in the working medium. It is easy to start up and does not require priming. The rotation direction, as viewed from the motor end, should be clockwise. The overall length is available in various specifications to allow users to select the most suitable size based on their specific application and location.

II. Product Application:

1. The NL type sludge pump is used in mining, papermaking, dyeing, environmental protection, graphite, mica, gold, ceramics, oil refining, petroleum, chemical industry, farms, salt fields, iodine fields, dyeing and chemical industries, winemaking, food, fertilizer, coking, selection plants, construction, marble factories, gold mines, mud, flowing sand, ponds, polluted ponds, and for transporting thick liquids, sludge, and suspensions containing solid particles. It can also be used for mine drainage and fluids containing mud blocks.

2. When paired with high-pressure water pumps and water cannons, this combination can form a hydraulic mechanical earthwork unit suitable for land leveling, channel and pond dredging, and other small-scale hydraulic engineering excavation and conveying, as well as for urban civil air defense projects and underground construction.

3. Fish farming for water purification, pond aeration, etc.
