Roots Vacuum Pump

The pump consists of two figures "8" shaped rotors and two semicircular pump houses. The rotors rotate synchronously in opposite directions and high speeding. The pump cannot be separate used; it must be used as boosters combined with a backing pump such as rotary piston or a rotary vane 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 mechanical vacuum pump)

Main features:
• The lack of reciprocating parts allows a perfect dynamic balancing, because the rotors are processed by numerical control machine tools and balanced carefully. It has perfect geometry symmetry. There is certain clearance between the two rotors. The pump house and end cover is processed by especial machine tools. It has high precision. So the pump own feature of stable operation, low noise, vibration and high ultimate pressure.
• The robust drive of pump and operating parts balanced carefully permit that the pump be stably operated continuously under the condition of high different pressure.
• They can be started quickly and in short time ultimate pressure is reached.
• Lubrication is unnecessary as there is no contact between rotors and house that avoid oil vapor from polluting vacuum system
• Good reliability characteristic. Their inherent overflow valve play auto-protective role.
• Compact structure, low footprint design. There are three gas outlet ports that are in left, right and under pump house. It is convenient for consumer installing.

The roots pumps are 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 dust cannot be pumped by roots pumps.
