AIDS Sludge Transfer
March 1st 2006

Robbins & Myers has introduced its 2000 HS System as an alternative to piston pumps and the higher maintenance, open conveyor systems typically used for dewatered sludge transfer in municipal wastewater treatment.

The system is said to handle a higher percentage of solids and pump it further than any other PCbased system. The pump package has a dual auger feed and advanced control system that boosts efficiency in handling semidry, high density solids, such as dewatered municipal sludge containing more than 50% solids.

It is designed to provide optimum performance for handling high solids filter cake applications.

Features include an ultra-feed rotor configuration which is designed to improve the flow efficiency of high solids content materials, and ultrashield rotor coatings that help the pump maintain peak performance and longevity. A non-pulsating flow results in elimination of pressure spikes , while a twin screw feeder inside the suction hopper supplies a constant, pressurised feed rate to the pump, resulting in a 100% pump cavity fill rate.
