Smart Air Injection pumps viscous media with a variable dry solids content over long distances. In the environmental industry, it is used to transport dewatered sludge with less energy required than common conveying systems. In this process, the pumped medium is first compressed in the progressive cavity pump to form long plugs, which are then pneumatically conveyed further along the path by extremely short compressed air pulses of a few seconds. Overall, only very little compressed air is required for conveying. This low energy requirement significantly reduces operating costs. Distances of up to 1,000 meters, with changes in direction, and differences in altitude are possible without any problems.
Seepex will give an insight into the intelligent SAI conveying concept, show application and functional areas, and provide evidence of these with numerous references.
