What is a Liquid Ring Vacuum Pump?
Liquid ring vacuum pump is a type of vacuum pump that uses liquid as a working ring to create vacuum pressure. This technology is based on the principle of forming a liquid ring inside the working chamber which is rotated by a rotor. This fluid is usually water or another fluid appropriate to the application, and the rotation of the rotor creates a liquid ring that functions as a seal separating the working chamber from the atmosphere.
Characteristics of Liquid Ring Vacuum Pumps
Liquid ring vacuum pumps have several main characteristics:
- Simple and Reliable: This pump has few moving parts, so it has a long service life and requires minimal maintenance. This makes it a reliable choice in a variety of industrial applications.
- Resistant to Dust and Particles: These pumps tend to be resistant to solid particles that can be found in the air stream or sucked gas, making them suitable for applications in dusty environments.
- Ability to Deal with Wet Gases: Liquid ring vacuum pumps are suitable for dealing with gases containing water vapor or liquid substances, because the working fluid (usually water) can handle moisture.
- Ability to Handle Variable Loads: These pumps are able to handle significant changes in load without breaking down, making them suitable for a variety of operational situations.
- High Level of Safety: Liquid ring vacuum pumps have a low risk of spills or leaks due to the liquid ring separating the working chamber from the atmosphere. This makes it safe to handle dangerous or toxic gases.
Benefits of Liquid Ring Vacuum Pumps
Liquid ring vacuum pumps offer several key benefits in industrial applications:
- Efficient Energy Use: This pump consumes a relatively low amount of energy compared to some other types of vacuum pumps.

Vacuum pumps have an important role in a variety of industries, assisting in a variety of processes and applications that require low pressure or vacuum environments. Reliability and efficiency in gas and air removal are the reasons why vacuum pumps continue to be widely used throughout the world.
How Does a Vacuum Pump Work?
A vacuum pump, or vacuum pump, operates by removing air and gas from a closed space to create a pressure lower than atmospheric pressure. There are several types of vacuum pumps, however, here we will explain how a rotary vane vacuum pump works, which is one of the commonly used types of vacuum pumps:
Rotary Vane Vacuum Pump
- Working Chamber: Rotary vane vacuum pumps have a well-sealed working chamber, where low pressure is created. This room is connected to the system or environment that you want to suck.
- Rotor and Vane: Inside the work chamber, there is a rotor that can rotate and is paired with several thin metal plates called "vanes" or blades. These vanes are usually made of wear-resistant materials, such as metal or plastic. This rotor is installed eccentrically, meaning that the rotor does not rotate in the center of the room, but with an axis that is eccentric or shifted from the center of the room.
- Working Fluid Ring: This vacuum pump uses liquid as a working medium. This fluid fills the space between the vane and the work chamber wall, forming a liquid ring that separates the work chamber from the outside atmosphere. This fluid is generally a special oil or lubricant that is suitable for the operational environment.
- Duty Cycle: When the vacuum pump is turned on, the rotor starts to rotate. The vane attached to the rotor will follow the shape of the work space as the rotor rotates. When the rotor rotates, the space between the vanes will change volume due to the eccentricity of the rotor.
- Suction and Extraction: As the rotor rotates and the vane fills the chamber, the pressure inside the working chamber drops. This causes air and gas from the connected system or external environment to enter the working chamber through the inlet valve. Next, as the vane moves further and the volume of the chamber decreases further, the liquid working ring helps compress the air and gas to an even lower pressure.
- Exhaust: Once the air or gas is compressed, they will be discharged through the exhaust valve. The vacuum pump continues to spin and repeats this cycle, removing more air and gas, and creating a lower vacuum pressure in the system.
- Maintenance: To maintain the performance of the vacuum pump, the lubricant or working oil must be monitored and replaced periodically. In addition, vanes and other components that are susceptible to wear also need to be checked and replaced as needed.
Rotary vane vacuum pumps are a type of vacuum pump that is commonly used in a variety of applications, including industry, research and general use. They can create vacuum pressure with a high degree of reliability and are an important component in many processes and systems that require a low pressure or vacuum environment.
Vacuum Pump Price
How much does a vacuum pump cost? Vacuum pump prices vary widely depending on several factors, including pump type, brand, capacity, quality, and additional features. Vacuum pumps can be purchased at a very wide price range, from hundreds to thousands of dollars or more. Here are several factors that influence the price of a vacuum pump:
- Pump Type: There are different types of vacuum pumps, such as rotary vane vacuum pumps, liquid ring vacuum pumps, membrane friction vacuum pumps, and more. Each type has different performance characteristics and will have a different price range.
- Capacity: The capacity or suction power of a vacuum pump is an important factor that influences the price. A vacuum pump with a large capacity will have a higher price than a pump with a small capacity.
- Brand and Quality: Well-known brands and higher quality pumps generally have higher prices. However, they often offer better reliability and service life.
- Additional Features: Some vacuum pumps come with additional features such as automatic controllers, monitoring systems, and special equipment for certain applications. These features can affect the price.
- Condition: New or Used Vacuum Pump: Purchasing a new vacuum pump will have a different price than a used or reconditioned vacuum pump. Used vacuum pumps are often more affordable but need to be checked carefully before purchase.
- Application Specialization: In some industries or applications that require specific specifications, vacuum pumps that meet special requirements can have a higher price.
- Suppliers and Distributors: Prices may also vary depending on the supplier or distributor you choose. Searching for quotes from several different sources can help you find more competitive prices.
