Dry vs. Liquid Ring Vacuum Pumps for Solvent Handling

Dry vs. Liquid Ring Vacuum Pumps for Solvent Handling

The most common and preferred vacuum pumps for han-dling solvents are Liquid Ring and Dry Pumps. Both types of pumps do not require internal lubrication which allows solvent vapors to be sucked through the pumps without jeopardizing their lubrication whereas oil sealed pumps such as rotary vane or piston that do require internal lubrication
