Description :
Roots vacuum pumps ,which are also called Roots blowers,are rotary plunger type pumps where two symmetrically shaped impellors rotate in opposite directions inside the pump housing.
Characteristics:
- The use of oil-free intermediat seal,multiple sealed way to ensure the hight clean vacuum environment in the rotor chamber .
- Advanced proceesing to ensure the good geometrical symmetry of the rotors,as well as low noise and long service life.
- The whole rotors is made of aluminium alloy which has the charateristics of fast corrosion resistance and energy-efficient.
