Products >> Vacuum Pumps
Users can define Water ring vacuum pumps as high pressure and vacuum creating devices, used in different industrial sectors. Due to the rotational movement of the rotor segment, a water ring is usually formed inside the vacuum chamber, focusing more towards eccentric shaft. These pumps are economical as well as easy in operation and have a long operational life. These pumps are available in the following versions:

 Vacuum Pumps Applications
Power Industry: They are used in power generating equipment in condenser venting where a pump with two impellers fixed inside a single pump body is used. This ensures maximum condensing before gas enters the vacuum pump. More load can be handled by the pump this way.
Sugar & Distillery Industries: They are used in pneumatic conveying of fly ash, in priming, de-aeration and condenser initial evacuation also.
Plastic Industries: Plastic Industries: They help in making PET containers and in degassing, drying and conveying processes.
Environmental Industry: This industry includes water treatment and recycling of water where vacuum pumps help in priming, dig-ester gas compression and waste water disposal.
Petroleum Refining Industry: The pumps help in processes involving cumene, phenol, ethylene glycol/ethylene oxide, ethyl benzene/styrene monomer, amines and alcohols. They are used in crude oil stabilization, crude oil vacuum distillation, filtering and de-waxing.
Paper & Pulp Industries: In paper making machinery vacuum pumps help dewater the pulp slurry and to extract water from press felts. Process vacuum needed in making of molded paper pulp products like packaging material for electronic items uses them.
Printing Industry: They enable powdering on printing presses, screen printers and used in the central system.
Chemical Industry : They can work well where there are low changes in temperature and flammable mixtures are used besides in distillation and degassing. Solvent recovery, vacuum filtration, vent gas compression are some uses.
Pharmaceutical Industry: The pumps help in drying, laboratory, vapor recovery, house vacuum and other uses. They help dry products and in recovering organic vapors. They provide house vacuum on production lines.
Packaging Industry: While packing food items whether raw or cooked vacuum packaging is used to preserve the food for longer duration. Tea leaves, Ready-to-Cook meals etc. come in vacuum packs which retain the freshness of the item as it was while packing.
Ceramic Industry : In the ceramic industry it is imperative to remove air bubbles which may form in the clay as it will make the ceramic product brittle. Vacuum pumps remove air from clay and used in vacuum processing.

 Working Principle
The water ring vacuum pump features a cylinder which has a central hub that is slightly offset to one side. The central hub has an impeller which has slightly curved blades. The blades are fixed such that those at the top of impeller are closer to the outside wall and those at the bottom of the pump are fixed far from the wall.
Two port plates with holes or ports are fixed at the two ends of the impeller. In water ring vacuum pump water is used as the sealant. Before switching on the pump the impeller blades remain immersed in water as the pump is partially filled with water.
When the vacuum pump is switched on the impeller rotates and throws the water towards the outer walls of cylinder like a sling owing to the centrifugal force creating a ring of water. As the impeller is offset to one side, some blades remain immersed in water and some are exposed. This produces an empty space or void lying between the blades and the water creating “an impeller cell.”
With continued rotation of impeller the water recedes from the hub and acts like a piston to create an even larger cell. A suction force is produced and the pump draws in air, gas or vapour through the suction port on the side. When impeller cell passes the suction port and moves towards discharge port a compression force is produced. When the impeller cell passes the discharge port compression is maximum, which throws out or expels the air or gases. Since the water is turbulent some of it also gets discharged. This continuous action creates a vacuum.
