Beijing Super Q Technology Co., Ltd. has EV series oil-lubricated 600L, 1200L, 1600L compound molecular pumps and 3600L turbine type molecular pumps; grease-lubricated 300L, 650L, 1300L, 2000L comp...
Rotary vane vacuum pumps are used as oil sealed pumps most of the time. During the use, some oil and gas will be expelled together with the pumped gas, resulting in oil spray. Therefore, rotary van...
The molecular pump is a vacuum pump that uses a high-speed rotor to transfer momentum to the gas molecules so that they gain directional velocity and are thus compressed, driven towards the exhaust...
Many vacuum process installations are equipped with a Roots pump on top of the pre-stage pump, both to increase the pumping speed and to improve the vacuum. However, the following problems are ofte...
