Gram BA.500 VOLUMETRIC ROOTS LOBE PUMP
The Bora-BA series volumetric roots lobe pumphave three lobe rotors with a unique geometric shape that emphasize the positive properties of this design and minimize the negative (ie: recycle of gas). In addition, the shaft seal is secured by a dynamic seal that prevents any leakage. These canister blowers must be used with a primary pump and increase the total flow at low working pressures and achieve a great improvement in final pressure. The most common applications are in the pharmaceutical sector, vacuum metal treatment, electric transformer oil degassing, food packaging.
