Figure below shows the internal structure of the Roots vacuum pump. The two rotors of the pump are supported in the rolling bearings on the end covers on both sides of the pump chamber, and rely on a pair of adjustable synchronous gears to keep the two rotors rotating at high speed. A certain mutual position, and the end face gap between the rotor and the end cover is guaranteed by the special structure of the fixed end (closer to the motor side), so that the pump can only expand to one end of the gearbox due to heat during operation.

Remark:
1. The pumping speed refers to the maximum pumping speed measured when the inlet pressure of the Roots vacuum pump is in the range of 67 Pa ~ 2.67 Pa under the condition that the recommended backing pump is used.
2. The ultimate pressure refers to the stable minimum air pressure measured at the inlet of the pump with a vacuum gauge after fully operation without any additional container, the pump port is closed and no intake air is provided under the condition that the recommended backing pump is used.
3. The performances in the above table are obtained under the condition that the recommended backing pump is used. Users can choose different backing vacuum pumps according to different situations, but their main performance data will vary.
Q: What information should I offer for an inquiry?
A: You can inquire based on the model directly, but it is always recommended that you contact us so that we can help you to check if the pump is the most appropriate for your application.
Q: Can you make a customized vacuum pump?
A: Yes, we can do some special designs to meet customer applications. Such as customized sealing systems, speical surface treatment can be applied for roots vacuum pump and screw vacuum pump. Please contact us if you have special requirements.
Q: I have problems with our vacuum pumps or vacuum systems, can you offer some help?
A: We have application and design engineers with more than 30 years of experience in vacuum applications in different industries and help a lot of customers resolve their problems, such as leakage issues, energy-saving solutions, more environment-friendly vacuum systems, etc. Please contact us and we'll be very happy if we can offer any help to your vacuum system.
Q: Can you design and make customized vacuum systems?
