Pressure-stable conveyance of thick sludge using progressing cavity pumps
About this Solution
Handling the thickened sludge presents a problem. This sludge can contain eight to eleven percent of dry matter content and, due to its composition, no features linear flow characteristics similar to water. However, in order to ensure consistent conveying at 4 bar, NEMO® progressing cavity pumps have been installed, for example, for transporting to and from the digestion tank. Whilst filling the chambers with the high viscosity medium, the stator inlet bevelled also assists.
