The global liquid ring vacuum pumps market is estimated to be valued at USD 1,197.1 Mn in 2025 and is expected to exhibit a compound annual growth rate (CAGR) of 4.8% during the forecast period, reaching USD 1,663.3 Mn by 2032.
The global liquid ring vacuum pumps market is expected to record steady growth during the forecast period. This is mostly due to rising demand for liquid ring vacuum pumps from the chemical, oil and gas, food & beverages, and pharmaceutical industries.
These industries need reliable and efficient vacuum solutions for various critical operations such as distillation, drying, filtration, degassing, and material handling. Liquid ring vacuum pumps are favored because they can handle wet and corrosive gases, provide consistent suction pressure, and operate with low noise as well as vibration.
For instance, Rezitech Services dispatched a brand new 2BV5-111 Liquid Ring Vacuum Pump to a food industry customer. This shows the growing adoption of these pumps in industrial processing environments.
Liquid ring vacuum pumps are also being increasingly used in wastewater treatment applications due to their compactness as well as tendency to handle large particles. Thus, expansion of wastewater treatment infrastructure will likely boost sales of liquid ring vacuum pumps during the forthcoming period.

Single-stage liquid ring vacuum pumps are anticipated to remain the top-selling type, accounting for 64.0% of the market share in 2025. This is due to their superior energy efficiency and ease of maintenance compared to other pump types.
Single-stage pumps require fewer moving parts and surface area compared to two-stage pumps. This makes them more efficient at transferring power into vacuum pressure.
They can achieve vacuum levels up to 27 inches of mercury using a single rotating assembly. This high level of vacuum power with fewer components means single-stage pumps convert a greater percentage of motor energy directly into airflow.
Their simple internal design also reduces maintenance needs. With no oil seals or dynamic gaskets required, single-stage pumps are largely maintenance-free and have much lower operating costs over time versus compressors or more complex multi-stage designs. This superior efficiency and convenience have made single-stage pumps the technology of choice for basic industrial vacuuming applications.
Cast iron is expected to remain one of the most widely used materials for liquid ring vacuum pump manufacturing, accounting for around 39% of the liquid ring market share in 2025. This is mostly due to its high strength, durability, and cost-effectiveness, even under demanding industrial conditions.
Cast iron offers key mechanical properties that make it suitable for vacuum pump components. Its high density and graphite microstructure provide excellent vibration damping and wear resistance, allowing pumps to withstand continuous operation, mechanical stress, and impact effectively.
As per Coherent Market Insights’ latest liquid ring vacuum pumps market analysis, chemical application is expected to dominate the industry. This segment will likely account for a market share of 35.1% in 2025, owing to the growing necessity of liquid ring vacuum pumps in varied chemical processes.
The chemical industry relies upon vacuum systems for many activities like distillation, evaporation, degassing, filtering, and others. Liquid ring pumps effectively meet chemical plant vacuum needs due to their corrosion resistance, oil-free operation, and ability to handle large volumes of vapor without contamination.
They are especially valued for venting in processes to recover solvents, separate mixtures of organics, produce high purity gases, and manufacture petrochemicals. Thus, growing adoption across the chemical industry is expected to boost liquid ring vacuum pump sales in the coming years.

The food and beverage industry has seen tremendous growth over the past few years. Changing consumer tastes and preferences, coupled with rising incomes, have led to the expansion of the processed and packaged food sector globally.
Manufacturing units in this industry require liquid ring vacuum pumps to draw vacuum in processes such as evaporation, freeze-drying, vacuum packaging, and bottling, among others. Vacuum is essential for removing oxygen from packaging to prevent oxidation of foods and extend their shelf life.
As per data by the UN Food and Agriculture Organization (FAO), the global food production is projected to increase nearly 70 percent between 2012 and 2050 to sufficiently supply the projected world population of 9.6 billion in 2050. This is expected to drive demand for liquid ring vacuum pumps during the forecast period.
Growth of process industries such as pneumatic conveying, drying, and evaporation is creating new opportunities for liquid ring vacuum pump manufacturers. These pumps are widely used in such applications due to their robustness, corrosion resistance, and ability to handle wet gas streams.
