Liquid-Ring Vacuum Pump

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

As the shaft turns, a liquid band is created by the centrifugal force produced by the rotating impeller. This power holds the liquid ring against the inner wall of the pumping chamber. Because the impeller is located eccentric to the pumping chamber, the depth of entry of the blades in to the liquid ring decreases and improves as the impeller rotates. This creates increasing cell quantity on the inlet interface side, creating vacuum.

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

A continuing flow of fresh sealing liquid is supplied to the pump via the sealing-liquid inlet.

In the case of the two-stage liquid ring pump, the discharge from the initial stage will not discharge to atmosphere. Instead, the first stage discharges through the manifold Liquid-Ring Vacuum Pump china leading to the second stage in addition to through a discharge slot located in the intermediate plate between the first- and second-stage impellers.
