Two-stage vacuum pump

A two-stage vacuum pump compresses gas step by step by connecting two pumping units in series, with the primary pump pre-pumping to a low vacuum and the secondary pump further compressing it to a high vacuum. It is used in environments requiring rapid and stable vacuum acquisition, such as laboratory sample pretreatment and vacuum drying.
Selection
Select the pump's ultimate pressure based on the required vacuum level, match the pumping speed with the container volume, choose corrosion-resistant models considering the composition of the gas being pumped, determine the motor power based on usage frequency, and select structures with lower noise and vibration according to the working environment.
