Guide to pumps for a biogas plant: types and applications in anaerobic digestion

In a biogas plant, choosing the right pumping technology is essential to maintain a continuous flow, prevent blockages and reduce costly downtime. Not all pumps handle sludge, silage, manure or solids-laden digestate in the same way, and this directly affects the reliability of the installation. The right pump does more than simply move the product: it protects the process, stabilises operation and helps the anaerobic digestion process perform as required.
