NEW TWIN SCREW PUMP FROM GEA REQUIRES 10 PERCENT LESS ENERGY DUE TO IMPROVED 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 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 percent with the new design, but also save ten percent energy thanks to the improved efficiency.
High flexibility with dual function
With variable speeds of up to 3000 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 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.
The GEA Hilge NOVATWIN+ screw pump has two screw spindles that interlock without touching and form a closed chamber together with the pump casing. When rotating, the twin screws minimize pulsation while conveying the medium along the screw axes from the suction to the discharge side. Source: GEA
Quick servicing through patented screw adjustment
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.
