The GEA Hilge NOVALOBE pump range meets the highest hygienic requirements and is EHEDG certified.
Robust Construction
Through the pump’s robust construction the shaft overhang and clearance in the pump have been minimized. The pump’s compact design and the rigid shaft geometry reduce the risk of galling to an absolute minimum. The GEA Hilge NOVALOBE range has thus been designed for a differential pressure of up to 16 bar.
Unique Rotor Mounting Design
Precision-ground cylinders for the location and accurate connection of rotors and shafts minimize play and reduce vibrations as well as noise.
Flexible Rotor Profiles
The rotor housing can be equipped with various rotor profiles. This makes it possible to adapt the GEA Hilge NOVALOBE pump to specific applications for an optimum performance in different conditions.
Shaft Seals
To accommodate different applications and media, GEA Hilge NOVALOBE pumps are available with different seal types:
- Single mechanical seal
- Single-flush mechanical seal
- Double mechanical seal
- O-ring seal
The mechanical seals are single inboard seals placed in the optimum position in the pump to ensure outstanding lubrication and cooling. They also comply with the hygienic design criteria in CIP and SIP processes.
Seal face materials are carefully selected to suit the specific media. Standard materials are carbon/silicon carbide with EPDM elastomers (FDA-compliant).

Additional options
Pressure Relief Valve
Positive displacement rotary lobe pumps will continue to build up pressure when operating against a closed valve. With this in mind, it is very important to add in a safety device to prevent accidental over-pressurization and subsequent damage to the pump or system. GEA Hilge NOVALOBE pumps can be equipped with an integrated pressure relief valve to avoid these damages.
Thermal Jackets
Thermal jackets are available for all pump sizes. This option makes it possible to heat the pump chamber and to ensure that products which solidify at ambient temperature are kept liquid. Alternatively, the thermal jackets can be used to cool the pumped media where necessary. Thermal jackets for GEA Hilge NOVALOBE are available for the rotor case and the front cover. Due to the integrated design in the pump, it is a highly efficient system without any compromise in the hygienic design and cleanability.
Aseptic Front Cover
Combining the benefits of a circulating barrier fluid and double mechanical seals, the aseptic front cover and the double mechanical seal greatly increase safety – ideal where high containment requirements apply.

Beyond the firewall: Securing what matters at GEA
Companies like GEA process and store large amounts of sensitive data. However, security incidents, from ransomware attacks to physical intrusions and industrial espionage, are ever-expanding. GEA’s effective protection of its business partners’ data – as well as its own proprietary information – is evolving into a competitive advantage. We spoke with Iskro Mollov, GEA’s Chief Information Security Officer, about what it takes to protect a global business in a volatile world.
