What type of vacuum pump system should be used for pumping systems containing butyl acetate at high vacuum?
Thread Content
For high-vacuum units that draw butyl acetate, is it practical to use a Roots-water ring vacuum unit configuration? Can rotary vane pumps and water ring pumps pump flammable and explosive fluids?
There is condensation at the front end; the butyl acetate content entering the back end is 24.77%
For specific details, it’s better to consult the manufacturers of water ring pumps or Roots pumps directly

It is recommended to use a Roots screw vacuum pump unit, with the pressure and pumping speed controlled via frequency conversion.
For solvent evaporation, it is recommended to use a dry vacuum pump; since the solvent does not mix with water, it can be condensed and recovered directly after passing through the pump, which is environmentally friendly and energy-efficient. For high vacuum, a dry rotary vane vacuum pump set is recommended. ——We also have another type: a vacuum pump designed specifically for extracting low-boiling-point solvents, an ultra-low vacuum dry vacuum pump intended for operation at a vacuum level of -0.08 to -0.09 MPa. It offers an excellent cost-performance ratio; feel free to ask for more details.
