Seeking advice on vacuum pump selection
Thread Content
Maximum suction pressure: 2 KPa; ultimate vacuum: 25 Pa; power: 11 kW; flow rate: 300 L/s; inlet pressure: 2 KPa; temperature: 50°C; non-condensable gas with density ρ=0.022 and specific heat u=0.02 CP; flow rate: 270 L/s at 2 KPa. These are the process parameters for the vacuum pump required by our company. Could experts please advise whether it is more suitable to choose a rotary vane or rotary screw pump system?
Choosing a Roots pump + water ring pump unit allows for the extraction of large amounts of condensable steam, with the water ring pump employing a bipolar design to enhance vacuum levels.
I recommend choosing a claw-type Roots blower. It has good stability and strong corrosion resistance. Feel free to call 18653370285 for inquiries.
