It is a mechanical pump with high evacuating speed also referred to as mechanical booster pump. The rotors rotate synchronously in opposite directions and high speeding. The pump cannot be used singly, it must be used as boosters combined with a backing pump such as a rotary piston or a rotary vane vacuum pump, or a liquid ring vacuum pump. These vacuum systems can get higher vacuum, a stable, fairly high pumping speed can be gained in effective pressure range.
The backing pump decides the ultimate pressure of roots pump. The data of the list is lowest ultimate pressure with the standard equipment (equipped double stage oil machine vacuum pump).
Typical Applications:
It can be used widely used in vacuum moulding, vacuum smelting, vacuum gas pumping, vacuum coating industry, vacuum distilling and vacuum drying of chemical and pharmaceutical industry etc.
The pump is insensitive to a little dust.
