Liquid Ring Vacuum Pump Supplier for Wet and Demanding Processes
When the gas you need to evacuate is wet, hot or loaded with vapour, a liquid ring pump is often the most dependable answer. N B Mercantile, exclusive channel partner for Atlas Copco in Rajasthan and in business since 1996, is a liquid ring vacuum pump supplier for the AWS, AWD and AWL ranges, intelligent liquid ring pumps with variable speed drive and complete liquid ring engineered systems.
How a liquid ring vacuum pump works
An impeller is mounted off-centre in a casing partly filled with service liquid, usually water. As the impeller turns, the liquid forms a rotating ring that seals the spaces between the blades. These spaces grow on the suction side, drawing gas in, and shrink on the discharge side, compressing it. The liquid also absorbs the heat of compression, so the pump runs cool and can handle condensable vapours and small amounts of liquid carry-over. This is why it is also called a water ring pump, and why buyers often search for a water ring vacuum pump supplier.
Typical applications
- Chemical and process plants: distillation, evaporation, drying and solvent recovery.
- Paper: dewatering on suction rolls and suction boxes.
- Sugar: vacuum pans, evaporators and filters.
- Food and beverage: deaeration, evaporation and filtration.
- General industry: vacuum filtration, priming and degassing.
Choosing the right pump
Key inputs are the required capacity, the operating vacuum, the gas and vapour load, and the service liquid temperature, since warmer liquid limits the vacuum the pump can reach. A variable speed drive helps where demand varies. For engineered systems, the choice between once-through service water and a closed recirculation loop with a separator and heat exchanger affects water consumption, so plants with limited water supply usually prefer partial or full recovery. The liquid ring vacuum pump price depends on model, capacity, materials and configuration, so we quote per application. If your gas is clean and dry, compare with our oil-sealed vacuum pumps or the full vacuum solutions range.

Liquid Ring Vacuum Pump FAQs
What is the difference between a liquid ring and a water ring vacuum pump?
They are the same type of pump. Water is the most common service liquid, so the term water ring pump is widely used. Other compatible liquids can be used in some processes, for example where solvent recovery is involved. The working principle of a rotating liquid ring sealing an off-centre impeller stays the same.
Why choose a liquid ring pump for wet or condensable gases?
The service liquid absorbs heat and condenses part of the vapour inside the pump, so wet, saturated or hot gases do not damage it the way they could harm an oil-sealed pump. It also tolerates small liquid slugs. This makes it reliable for chemical, paper, sugar and food processes with heavy vapour loads.
What factors affect liquid ring vacuum pump price?
Price depends on pumping capacity, required vacuum, construction materials, motor rating, whether a variable speed drive is fitted, and whether you need a bare pump or a complete system with separator, heat exchanger and controls. We quote each requirement separately. Share your process details with us for an accurate quote.
How does service liquid temperature affect performance?
The lowest vacuum a liquid ring pump can reach is limited by the vapour pressure of its service liquid. Warmer water evaporates more easily, which reduces capacity at deep vacuum. Keeping the service liquid cool, through fresh supply or a recirculation system with a heat exchanger, helps the pump hold its rated performance.
