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 needed in its procedure. This liquid could be water, essential oil or any various other solvent which can be rotated by an impeller within the casing of the pump.

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

On the discharge port side, the impeller cell volume decreases as the blades move further into the liquid band. This increases the pressure until discharge takes place through the discharge port.

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

Regarding the two-stage liquid band pump, the discharge from the initial stage does not discharge to atmosphere. Rather, the 1st stage discharges through the manifold leading to the second stage and also through a discharge slot situated in the intermediate plate between your first- and second-stage impellers.
