Water recovery modules Are offered with stainless steel wetted parts as standard, irrespective of the materials of construction of the pump. Suitable for a wide range of applications The new AW series of standard liquid ring vacuum packages are perfect for use in humid, liquid ring vacuum pump and dirty environments commonly found in industrial processes.

Liquid Ring Vacuum Pumps

Liquid ring pumps are equipped with a fixed blade impeller located eccentrically within a cylindrical casing. As the impeller rotates, liquid usually water is thrown out by centrifugal force to form a liquid ring around the circumference of the casing, sealing the liquid ring vacuum pump of the impeller and creating separate enclosed gas chambers between each blade.

As liquid ring vacuum pump result of the eccentric position of the impeller, these chambers vary in volume as the shaft rotates, having the effect of drawing in and compressing process gas.

The AW liquid ring vacuum pumps are available for both single and two stage pumps.

In some systems, the discharged ring-liquid is cooled by a heat exchanger or liquid ring vacuum pump towerthen returned to the pump casing.

In some recirculating systems, contaminants from the gas become trapped in the ring-liquid, depending on system configuration.

Liquid-ring pump

These contaminants become concentrated as the liquid continues to recirculate, eventually causes damage and reduced life to the pump. In this case, filtration systems are required to ensure that contamination is kept to acceptable liquid ring vacuum pump.

In non-recirculating systems, the discharged hot liquid usually water is treated as a waste stream. In this case fresh cool water is used to make up the loss.

Environmental considerations are making such "once-through" systems increasingly rare. These simple, but highly reliable pumps have a variety of industrial applications. They are used to maintain condenser vacuum on large steam-turbine generator sets by removing incondensable gasses, where vacuum levels are typically 30—50 mbar.

They are used on paper machines to dewater the pulp slurry and to extract water from press felts. Another liquid ring vacuum pump is the vacuum forming of molded paper-pulp products egg cartons and other packaging.

Other applications include soil remediation, where contaminated ground water is drawn from wells by vacuum. In petroleum refining, vacuum distillation also makes use of liquid-ring vacuum pumps to liquid ring vacuum pump the process vacuum. By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so-called liquid ring.
