Submerged pump for grease sludge

A waste water treatment plant had persistent problems with a centrifugal pump which was used for pumping grease sludge. The submerged centrifugal pump pumped the sludge from the grease sludge basin into a storage shaft from which a second pump fed a digestion tower with the grease sludge. Higher TS contents caused problems to the centrifugal pump. The recurring blockages of the pump and the complex maintenance work resulting from them were the reason why the operator of the waste water treatment plant looked for an alternative pump technology.

Following intensive research, the customer decided to purchase a submerged Börger rotary lobe pump. Due to its ability to pump with stable pressure, the Börger rotary lobe pump can convey the viscous grease sludge from the grease sludge basin into the digestion tower directly. A storage shaft and a second pump are not necessary any more.

The customer is very satisfied with the new grease sludge pump. Since the customer has been using the Börger rotary lobe pump there have not been any failures caused by the pump even with high TS contents of the pumped medium.
