BOWAH VACUUM is a specialist manufacturer/exporter of vacuum products based in China. We have our own factory producing vacuum products. We also have a carefully selected small group of partner factories mostly located in the Zhejiang and Guangdong area that we work with to be able to offer a much wider and more complete range of vacuum products.
How does a rotary vane vacuum pump work?
The oil sealed rotary vane vacuum pump working principle is relying on the centrifugal force and the tension of the spring to keep the top of the rotary vane in contact with the inner wall of the pump chamber, the rotation of the rotor drives the rotary vane to slide along the inner wall of the pump chamber.
Vacuum Pump for Electron Microscope
A vacuum pump is an essential component of an electron microscope as it is required to create and maintain a vacuum environment within the microscope's chamber. The vacuum is necessary because air molecules can interfere with the path of the electrons as they travel from the electron source to the sample and then to the detector, reducing the resolution
Vacuum Pump for Lyophilizer
A lyophilizer vacuum pump is a critical component in the operation of a freeze dryer or lyophilizer. It is responsible for creating the vacuum necessary to carry out the lyophilization process.
Maintenance of two-stage rotary vane vacuum pump

how to detect leaks in a vacuum system?
Leak Detection in Vacuum System Equipment is to follow the processing technology (especially the welding process) to carry out leak detection on the semi-finished parts in time and to detect leaks in the process of vacuum system equipment installation.
How to choose a backing pump for a roots pump?
This compression ratio determines the capacity of the backing pump because the compression ratio is inversely proportional to the pumping speed of the two pumps. Generally, the compression ratio is selected within 2~10.
How diamonds are grown in a vacuum?
The production technologies for growing diamonds mainly include HPHT (High-Pressure High Temperature) method and CVD (Chemical Vapor Deposition) method, and the cultivation time is about half a month to one month.
How to choose a vacuum pump？
1. The selected vacuum pump must be able to extract the gas released during the process. 2. The ultimate vacuum degree of the selected main pump must be higher than the vacuum degree required by the pumped container.
