Sales start for GEA Hilge NOVATWIN: Complete portfolio for hygienic screw pumps

"Together with the proven and reliable GEA Hilge NOVALOBE rotary lobe pump, we are consistently expanding our competence in the positive displacement pump sector. As one of the technology leaders in this field, the different markets quite rightly demand top pumps with a high degree of flexibility for optimal adaptation to their individual customer needs. Solutions à la "one pump fits all" are not very effective and are neither our philosophy nor our claim. The addition of this promising pump type to the portfolio alongside the established rotary lobe pump GEA Hilge NOVALOBE will significantly strengthen GEA's position in the positive displacement pump sector. We are now in an even better position to cover the various customer requirements with the ideal pump solution from our own broad product portfolio," says Stefan Andresen, Business Development Manager Hygienic Pumps.

The special feature of the twin screw pump is its dual function, as they can not only pump the actual, often highly viscous product, but can also function as a CIP pump, as they can also be operated at very high speeds. Compared to alternative solutions, the use of an additional CIP pump can thus be saved.

The self-priming, hygienic GEA Hilge NOVATWIN enables safe operation with low pulsation and low noise levels at high product viscosities, temperatures up to 135°C and differential pressures up to 25 bar. The system pressure of 30 bar also allows the pump to be used in high-pressure applications. It enables one pump to handle both sensitive viscous media at low speed and cleaning media in the CIP process at up to 3,000 rpm. A constant flow at different pressures and volumes is another advantage. Due to its self-priming property (suction height up to 8 meters), other application areas can be served.

For special requirements due to the pumped medium, GEA offers additional options such as a heatable or hardened pump housing. The heatable housing as an option allows the pump chamber to be heated or cooled depending on the temperature requirements of the pumped medium.

Keyword "hardened pump housing": In case of abrasive media the screw spindles and additionally the pump housing can be hardened to increase the lifetime of the pump. Due to the low-pulsation and gentle pumping, the properties of the pumped media are retained in their appearance, structure and size. By using different screws with different pitches, the pump can be optimally adapted to the pumped medium in terms of solid size and differential pressure. This also enables gentle pumping such as yoghurt with pieces of fruit or meat salads with solids with a diameter of up to 44 mm.
