Vane pumps are commonly used as high-pressure hydraulic pumps and are used in automobiles, including booster pumps, power steering pumps, air conditioning pumps, and automatic transmission pumps. Pumps used for medium pressure include applications such as fountain soft drink dispensers and espresso machine carbonators. In addition, vane pumps can be used in low-pressure gas applications, such as secondary air injection for automatic exhaust emission control, or for low-pressure chemical vapor deposition systems.

The rotary vane pump is also a common vacuum pump, and its two-stage pump can reach pressures well below 10-6 bar. These vacuum pumps have a variety of applications, such as in large trucks and diesel-powered passenger cars (the engine does not generate intake vacuum) through the brake booster to provide brake assistance, in most light aircraft used to drive gyroscopic aircraft to exhaust Empty refrigerant. During the installation of the air conditioner, the production line test is carried out in the laboratory freeze dryer, and the physical vacuum experiment is carried out. In vane pumps, the pumped gas and oil are mixed inside the pump, so they must be separated externally. Therefore, the inlet and outlet have a large chamber, possibly with swirling flow, where the oil droplets fall out of the gas. Sometimes, there is a venetian blind at the entrance, which is cooled by indoor air (the temperature of the pump is usually 40 K), to condense the broken pumped oil and water, and then let it drip back into the entrance. When these pumps are used in high vacuum systems (the flow of gas into the pump becomes very low), an important issue is that the backflow of molecular oil can contaminate the entire system.
