The vacuum pump's suction and exhaust use a conical distributor structure. The cross-sectional area of the suction and exhaust channels is large, and the flow resistance is small, making it more energy-efficient when removing dry air and saturated water vapor. Moreover, the two ends of the impeller are sealed and have good rigidity. The CL series conical liquid ring vacuum pump is often used in applications such as filtration, solvent recovery, desulfurization, vacuum distillation under reduced pressure, dehumidification, condenser vacuum pumping, and water diversion.
