With the expanding demand for semiconductors, for electronic device production, the Chinese vacuum pump market would grow to $1.9 billion in 2024, from $1.2 billion in 2018. From 2019 till 2024, the market is predicted to witness a CAGR of 8.7%.
Though they operate at low electrical power, they have a frequency inverter, controlled by a microprocessor, which results in a high starting torque. Due to the absence of a circuit breaker, such devices are cheaper than traditional ones.

Momentum-transfer, positive-displacement, and regenerative are the three major types of such devices. Positive-displacement vacuum pumps further come in the diaphragm, rotary-vane, piston-pump, liquid-ring, and dry-screw types. Among these, liquid-ring-type positive-displacement pumps saw the highest usage during 2014–2018, as these can be used for different gases, by altering the discharge temperature, thereby offering more flexibility.
The major applications of such devices are vacuum condensation, vacuum distillation, ash and air handling, moisture extraction, and mineral beneficiation, in an array of industries, including oil & gas, petrochemical, chemical, seawater deaeration, distillery, fertilizer, pharmaceutical, sugar, paper, railways, power, food & beverage, textile, and mineral.
Among these, the use of vacuum pumps in the chemical & pharmaceutical sectors is significant. Here, such equipment is primarily used for distillation, drying, filtration, solvent recovery, crystallization, and gas boosting, apart from the degassing of oils, glues, polymers, and water. In 2018, China was the largest producer of chemicals and also their largest user, holding a 37.0% share of the global chemical sales.
A key China vacuum pump market opportunity is the development of smart vacuum pumps. With the use of the frequency inverter technology, they work with a range of voltages and frequencies, to offer optimal and consistent performance. Unlike conventional models, they have two cylinders, which assist in fast evacuation of gas and air molecules.
The major reasons for the growth of the chemical sector in the country are the easy availability of labor and raw materials at low costs, government subsidies, and relaxed environmental norms.
Therefore, with the adoption of new technologies to increase semiconductor, pharmaceutical, and chemical production, the sale of vacuum pumps would continue surging in China.
