The BA. 500 is a volumetric roots lobe pump that has three lobe motors with a singular geometrical shape. It has a shaft sealing made of hermetic seal that prevents the possibility of any leakage. A primary pump should be used to increase the total flow rate even at a low operating pressure.
The rotary pump can reach a much better flow rate if it has a displacement pump because it increases the final vacuum created. It can be applied to pharmaceutical sector, vacuum metal treatment, electrical transformer oil outgassing and food packaging.
