Flotation sludge

In the waste water treatment system of a manufacturer of soft foam rubber a Börger rotary lobe pump sucks the flotation sludge from the surface of the flotation tank. In the process, the viscous, foam-like sludge is sucked through a long suction line. Pumping in slurp operation is possible without problems and the pump is capable of running dry for a short time. The pump even conveys the more solid flotation layers without any cavitation and is resistant to changing proportions of gas in the pumped medium.
