Anaerobic digestion circulation

In 1999, in a Bavarian waste water treatment plant, the operator decided to use a Börger rotary lobe pump for digestion tower convection. After the Börger rotary lobe pump had operated 24 hours a day for two years without problems, the treatment plant operator was so impressed that he ordered and used more Börger pumps. The pump from 1999 has operated without problems since then. The other Börger rotary lobe pumps have not failed so far either. The rotors of the pump are equipped with replaceable lobe tips. Only the lobe tips have been replaced since 1999.
