Liquid-Ring Vacuum Pump

A liquid ring vacuum pump is simple to operate and can be used in a number of applications across various industries. A liquid band pump works together with a sealant needed in its procedure. This liquid could be water, oil or any additional solvent which is definitely rotated by an impeller within the casing of the pump.

As the shaft turns, a liquid band is established by the centrifugal force produced by the rotating impeller. This power holds the liquid ring against the inner wall structure of the pumping chamber. Since the impeller is located Liquid-Ring Vacuum Pump china eccentric to the pumping chamber, the depth of access of the blades in to the liquid ring decreases and boosts as the impeller rotates. This creates increasing cellular volume on the inlet port side, creating vacuum.

On the discharge interface side, the impeller cell volume decreases as the blades move further in to the liquid ring. This increases the pressure until discharge occurs through the discharge port.

A continuous flow of clean sealing liquid is supplied to the pump via the sealing-liquid inlet.

Regarding the two-stage liquid ring pump, the discharge from the initial stage does not discharge to atmosphere. Rather, the initial stage discharges through the manifold resulting in the second stage as well as through a discharge interface located in the intermediate plate between your first- and second-stage impellers.
