The global liquid ring vacuum pumps market size was US$ 1.90 billion in 2021. The global liquid ring vacuum pumps market size is forecast to reach US$ 3.10 billion by 2030, growing at a compound annual growth rate (CAGR) of 5.6% during the forecast period from 2022 to 2030.

There are many applications for liquid ring vacuum pumps and compressors across most chemical process industries, particularly those requiring solvent recovery, vacuum filtration, and vapor recovery. In addition, specialized applications such as chlorine or hydrogen compression, vinyl chloride monomer recovery, etc., require vacuum pumps, and liquid ring vacuum pumps are the best option. Liquid ring vacuum pumps are rotating positive displacement machines used in many industrial fields, including chemical, electrical power, environmental, food & beverage processing, mining, oil & gas, pharmaceuticals, pulp & paper, and textiles. A liquid ring vacuum pump's simple operation and lack of contacting parts make it a safe and reliable choice for handling dirty and potentially hazardous gas streams.

Factors Influencing Market Growth 

• Over the forecast period, factors such as an increasing application in the chemical industry, rising demand from a wide range of industries, and low maintenance and operation costs are driving the global market growth.
• There is a growing demand for eco-friendly compressors due to rising emission levels and increased fuel use in compressed air systems. Materials used for these pumps allow them to withstand volatile gases and vapors without compromising their performance. Gases in the cavity of the pump compress at the same temperature so the pump can handle explosive gases safely. Thus, these factors are forecast to provide lucrative growth opportunities for the liquid ring vacuum pumps market.
• The majority of industrialized nations have imposed strict rules and regulations that must adhere to when using compressors, slowing the global market growth.

Impact Analysis of COVID-19

Following the COVID-19 outbreak, demand for petroleum and petroleum products from the major end-users of liquid ring vacuum pumps declined substantially. In response to a decline in demand and an unexpected decline in supply, crude oil prices dropped, which had a corresponding effect on refined petroleum products. Also, for the years 2020 and 2021, the global petroleum demand decreased compared to 2019. In turn, this has affected the growth of the liquid ring vacuum pumps market in the oil & gas industry. 

Regional Insights

North America accounted for the largest share in 2021. As a result of continuous expansion in oil-producing countries such as the Middle East and North America, this increase can attribute to the oil and gas industry. The region's water and wastewater treatment plants increasingly rely on liquid ring vacuum pumps.

Asia Pacific is forecast to grow at a high CAGR during the forecast period. Raw materials and labor are easily available at low rates, enticing investors to build production facilities in the region. As a result of low production costs and local government support, industrial activity increases in this area. In addition, increasing investments in research & development are driving the liquid ring vacuum pumps market in the Asia Pacific region.
