Roots Vacuum Pump

Roots Vacuum Pump

It is a mechanical pump with high evacuating speed also referred to as mechanical booster pump. Fast start with speedy evacuation in the vacuum condition of 1000~1Pa, it can achieve its ultimate pressure within a shortest possible time. But it can not operate individually. It must be in combination with its fore stage pump that makes it possible to start work by making the pressure permissible at its inlet.

It is widely used in vacuum coating, metallurgical industry for degassing, vacuum treatment for molten steel and vacuum simulation for space chamber or space capsule, etc, in chemistry, food, medicine, motor making industries as well as distilling, evaporating and dry process.

Advantages:

1. The lack of reciprocating parts allows a perfect dynamic balancing, because the rotors is processed by numerical control machine tool 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 tool. It has high precision. So the pump own feature of stable operation, low noise, low vibration and high ultimate pressure.

2. The robust drive of ump and operating parts balanced carefully permit that the pump be stably operated continuously under the condition of high different pressure.?

3.They can be started quickly, and in short time ultimate pressure is reached

4. Lubrication is unnecessary as there is no contact between rotors, rotor and house, that avoid oil vapor from polluting vacuum system.

5. Good reliability characteristic. Their inherent overflow valve play auto-protective role.

6. 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.
