Sludge Vacuum Pump / Solids Vacuum Pump
A sludge vacuum pump is a kind of high-load and strong suction vacuum conveyor also called a solids transfer pump or drill cuttings conveyor, sludge vacuum conveyor, etc. Its unique structure design enables it to work in the harshest environments with a low maintenance rate and high efficient transport of the following materials:
- 100% solid phase materials – sand, stones, etc.
- high specific gravity materials – solid-liquid mixture, powdery
- high viscosity materials – oil sludge, waste mud, drill cuttings, etc.
A sludge vacuum pump contains a high-efficiency venturi device where high vacuum degrees are produced to suck the materials under the effect of strong airflow. There are almost no wearing parts in the main body of the vacuum pump. It has a compact structure and is convenient for transportation and installation.
This negative pressure solid transfer pump has a wide range of applications: such as waste slurry and drilling cuttings, mud and tail slurry, mud pit cleaning, hazardous waste recycling, oil sludge, tank bottom cleaning, bilge cleaning of transport ships, bulk tanks, and material transportation in silos, transportation of sand, fine sand and fracturing sand, powdered materials, animal manure, etc.
