Flexibility and Reliability with Liquid Ring Vacuum Pumps
Liquid ring vacuum pumps are a common choice when it comes to flow-through systems. They offer flexibility for both full and partial recirculation. Although different liquids can be used, water is usually applied.
The operation of a liquid ring vacuum pump revolves around an eccentrically mounted rotor at the heart of the pump. This rotor is partially filled with an operating fluid. When the rotor rotates, the rotor blades come into contact with this liquid. This creates an internal fluid ring due to the centrifugal force that occurs.
At DOVAC, we offer several versions of liquid ring vacuum pumps, including single-stage and two-stage versions. The main difference between the two is the ability to achieve higher vacuum levels.
With their reliable operation and versatile applications, liquid ring vacuum pumps are an essential part of many industrial processes. In case of questions or for more information, we are always at your service.
The strength of liquid ring vacuum pumps also lies in their ability to operate efficiently in challenging environments. They are particularly effective at handling saturated gases and vapors without significant reduction in their performance, making them highly suitable for applications in process industries and food production, where moist or changing loads are common. In addition, the use of water or other operating fluids allows the pump to regulate internal temperatures and maintain consistent operation under varying process conditions.
In addition, our liquid ring vacuum pumps are known for their robust construction and long service life. These pumps require relatively little maintenance, thanks to their simple but effective design where there are few moving parts that can wear out. This makes them a cost-effective choice for many companies, especially in industries such as beverage and automotive, where reliability and durability are critical factors. The ability to support both light and heavy industrial applications strengthens their position as a versatile solution for various vacuum needs. This versatility is further enhanced by the ability of our liquid ring vacuum pumps to operate with different operating fluids depending on the specific requirements of the application, making them adaptable to almost any industrial environment.
