2BV5111 Liquid Ring Vacuum Pump
The 2BV5111 Liquid Ring Vacuum Pump is a high-quality vacuum pump with a compact structure and small volume. It is a single-stage pump that operates based on the water ring principle. The impeller, made of stainless steel, is installed eccentrically inside the pump body. When the pump starts up, a working liquid forms a concentric liquid ring inside the pump body. The impeller passes motor power to the liquid ring, which creates pulsation. Gas is then suctioned in through the disk suction inlet and discharged from the disk exhaust vent.
