Our Product | The SteriLobe® Series
1 | Improved Yield
Rotary lobe pumps offer high efficiency pumping at full range. The flow rate is largely independent of changes in pressure. Additionally, you can expect low shearing and expert handling of fluids prone to flashing.
The flow through a rotary lobe pump is proportional to speed. It provides easy control of flow rate with a variable speed drive for excellent metering capabilities. Paired with simple maintenance that can be done without removing the pump from the system, the SteriLobe® rotary lobe pump is your best solution for your pharmaceutical application.
2 | Scalability
Product offerings from benchtop system with flow as low as 10 l/min up, through pilot scale flow range up to full production with flow up to 2 m³/min (120,000 l/hour).
3| Clean in Place & Sterilize in Place
With an aseptic design the Sterilobe can be cleaned to the highest level in place or due to high temperature design also steam/sterilize in place.

Vaccine
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.
