Lobe Pumps

The volumetric roots pumps Bora – BA series are equipped with three lobe rotors having a singular geometrical shape that emphasizes the positive aspects of this design and annulling the negative ones (i.e.: gas recirculation). Moreover, the shaft sealing is ensured by a dynamic gasket preventing any leakage.

These pumps should always be used together with a primary pump increasing the total flow rate at low operating pressures and reaching a great improvement of the final pressure.

Typical applications of these pumps are in farmaceutical sector, in vacuum metal treatment, in electrical transformer oil outgassing, in food packaging.
