GEA new twin screw pump reduces energy usage, improves efficiency
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, according to GEA, and, thanks to its higher flow rate, covers a wider range of applications with a smaller pump. Customers not only reduce their material footprint by 23 per cent with the new design, but also save ten per cent energy thanks to improved efficiency.
High flexibility with dual function is assured with variable speeds of up to 3,000 rpm, the self-priming positive displacement pump conveys lumpy, shear-sensitive and abrasive media particularly gently. It can handle liquids with an exceptionally wide range of viscosities.
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 new in-demand 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,” explains Stefan Andresen, GEA’s product panager for positive pisplacement 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 – as for the dairy industry.
GEA’s pump experts have 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.
