GEA’s new twin screw pump for conveying and cleaning

GEA is launching a new generation of twin screw pumps for food, beverage and pharmaceutical applications that combine both conveying and cleaning functions in one pump.

The revamped GEA Hilge NOVATWIN+ is more powerful than its predecessor series and, with its higher flow rate, covers a wider range of applications with a smaller pump. The new design reduces the material footprint by 23%, while the improved efficiency saves 10% energy.

With variable speeds of up to 3000 rpm, the self-priming positive displacement pump conveys lumpy, shear-sensitive and abrasive media particularly gently. Since the GEA Hilge NOVATWIN+ operates almost without pulsation, it is also suitable for large and sensitive particles, for example, in the processing of cheese curds, quark, yogurt and high-protein beverages, as well as plant-based products.

“Especially the dairy industry with its complex products benefits from the dual function. Twin screw pumps can also serve as CIP pumps because they can be operated at very high speeds," said Stefan Andresen, GEA's Product Manager for Positive Displacement pumps. “This means that manufacturers eliminate the need for an additional CIP pump or even the CIP return pump necessary with alternative solutions." The system pressure of 30 bar also allows for use in high-pressure applications – another advantage for the dairy industry.

GEA has also simplified the maintenance of the NOVATWIN+ by integrating the blocking tool for tightening and untightening screws in the gearbox. This patented adjustment directly on the screws does not require oil drainage or complete disassembly of the pump.
