The sludge vacuum pump, also known as a solid conveying pump or cuttings conveying pump, is a powerful pneumatic vacuum conveying pump designed for high load and strong suction. It can pump a wide variety of materials, including solids, powders, liquids, and solid-liquid mixtures. This pump achieves a high vacuum degree, up to 25 inches of mercury (85 Kpa), and can discharge water to a head of 80 meters. Its unique structure allows it to work in particularly harsh environments with low maintenance.
It is capable of transporting materials where the solid phase exceeds 80% and materials with a high specific gravity at high speed. This makes it an ideal solution in the environmental protection field for the suction and transportation of solid particles, solid-liquid mixtures, and powders. In the petroleum industry, its applications include transporting drilling cuttings and oily sludge, cleaning tanks, long-distance waste suction, and the transportation of minerals and waste.
Advantages of Sludge Vacuum Pump
1. Strong suction capacity, long delivery distance, suction distance up to 50 meters, discharge distance up to 500-1000 meters;
2. Used for conveying a wide range of materials(liquids, mixed liquids, solids, powder)
3. The maximum particle size of solid materials that can be transported is 50mm or 75mm, and the solid content of the mixed liquid can be transported up to 80%;
4. Pneumatic work, no power supply, meet the requirements of the explosion-proof area;
5. Compact structure, easy to move;
6. Work automatically and continuously, easy to operate and maintain;
7. No rotating parts in the cavity, long service life.

Working principle of sludge vacuum pump
When the compressed air passes through the pump body under pressure, it will generate a high vacuum in the pump tank, and the material will enter the pump tank through the suction line. After a few seconds, the valve will reverse the direction of the airway, creating a positive pressure inside the pump tank, forcing the material out of the pump tank through the discharge line. The HLSP-40A model can work in manual mode and automatic mode, and the two models HLSP-10A and HLSP-20A can only work in automatic mode. Since it does not require electricity but only needs compressed air, HL solid vacuum pumps can be safely used in industries with explosion-proof requirements such as oil and gas and coal.
