Sludge vacuum pump, also known as solids transfer pump or drill cuttings transfer pump, is a pneumatic vacuum transfer pump with high load and strong suction. It creates a vacuum pneumatically for suction and then converts to positive pressure for material discharge. The unique design of this pump, with no rotating parts in the chamber, allows it to operate in the toughest environments with low maintenance and to transport materials with more than 80% solids and high specific gravity materials at high speed. The sludge vacuum pump has the following features:

High-efficiency venturi unit generates vacuum up to 25 inches HG (mercury column), equivalent to 85 kPa, with virtually no wear parts in the presence of strong air flow.
Compact pump body for conveying distances up to 500-1000 metres.
Commonly used for a wide range of applications such as drilling cuttings conveying, oily sludge conveying, tank emptying operations, waste pumping over long distances, as well as mineral and waste conveying.

The advantages of sludge vacuum pump include:

High self-priming capacity and long conveying distances, with suction distances of up to 50 metres and discharge distances of 500-1000 metres.
Wide range of materials that can be used for conveying, from liquids, mixed liquids to solids.
The maximum particle size of solid materials that can be conveyed is 50mm or 75mm, and the solid content of mixed liquid can be conveyed up to 80%.
Pneumatic work, without power supply, can meet the requirements of explosion-proof area.
No rotating parts in the chamber, not easy to wear and tear, long service life.
Can work automatically and continuously, easy to operate and maintain.
Compact structure, easy to move.
The technical parameters of sludge vacuum pumps include maximum conveying capacity, inlet and outlet diameters, vacuum degree, maximum suction distance and maximum discharge distance of different models, which can meet the sludge treatment requirements of different industries.
