11.06.2018 Large rotary lobe pump for sensitive products

GEA, Düsseldorf, Germany, has expanded its NOVALOBE pump range with the introduction of the large-volume GEA Hilge NOVALOBE 60. The robust rotary lobe pump is specifically designed for pumping and dosing highly viscous media, also with large particles. This new development meets the hygiene standards of EHEDG guidelines for applications in the pharmaceutical, chemical and food industries.
The Hilge NOVALOBE SERIES is part of the GEA VARIPUMP line which has acquired a reputation for versatility and flexibility. A year of successfully field-testing the NOVALOBE 60 in a sugar factory confirmed its strengths in daily operation: Production managers at the factory found it easy to operate and wear parts could be replaced without any retrofitting. The internal mechanical seals can be replaced from the front without removing the pump. These seals are lubricated and cooled optimally, thereby significantly extending the unit’s service life. GEA ensures hygienic cleanability and sterilisation with its choice of seals.
When the pump is running, the extremely quiet operation is clearly noticeable. GEA achieves this with its patented rotor mounting design. Precision-ground cylinders for the location and accurate connection of rotors and shafts minimise clearance and reduce vibrations as well as noise. Various rotor profiles are available for the NOVALOBE depending on the application: The single-bladed “uni-wing” is suitable for very doughy media containing large particles. The twin-bladed “bi-wing” rotor is the robust standard variant for most applications. A rounded, four-lobe rotor “multilobe” helps to convey shear-sensitive products at low pulsation.
