The volumetric roots pumps of Bora - BA series are equipped with three lobe rotors having a singular geometrical
shape emphasizing the positive characteristics 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 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.
The most common applications are: farmaceutical sector, vacuum metal treatment, electrical transformer oil
outgassing, food packaging.
