A Liquid-Ring Vacuum Pump china liquid band vacuum pump is simple to operate and is used in several applications across various industries. A liquid ring pump works together with a sealant needed in its procedure. This liquid can be water, essential oil or any other solvent which is usually 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 drive holds the liquid band against the inner wall structure of the pumping chamber. Because the impeller is situated eccentric to the pumping chamber, the depth of entry of the blades in to the liquid ring decreases and boosts 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 ring. This escalates the pressure until discharge takes place through the discharge port.

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

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