Rotary vane vacuum pumps are a type of pump that consists of vanes mounted to a router that rotates inside of a cavity. Their purpose is to facilitate the compression of air inside the pump’s chamber in order to create suction so air molecules can be removed from an area or vessel. These pumps work on a positive-displacement pumping principle and are used in a wide range of different applications. Below, we will go over some of the most common uses for rotary vane vacuum pumps.

Uses in the Automotive Industry

Rotary vane vacuum pumps are most commonly used in the automotive industry, where they serve as key components in a variety of vehicle parts. For example, rotary vane pumps are used to pressurize hydraulic fluid in power-steering systems. In addition, they are also used in automatic transmissions as fixed and variable-output units. Other vehicle components that frequently rely on these pumps include power brakes and superchargers.

Uses in the Laboratory Industry

Rotary vane vacuum pumps can also be used in the laboratory industry. In cases when a higher vacuum of 0.001 Torr is required, rotary pumps are highly beneficial. Common applications of rotary vane vacuum pumps in the laboratory industry include degassing, distillation drying, fractionation, vacuum filtration, and crystallization, just to name a few.

Uses in the Industrial Industry

Industrial industries also benefit from the capabilities of rotary vane vacuum pumps. Some of the many industrial systems that rely on rotary vane vacuum parts for their operation include drying systems, industrial furnaces, and dust extraction systems. 

Uses in the Beverage Processing Industry

Another industry that benefits from rotary vane vacuum pumps is the beverage processing industry. For example, espresso machines utilize rotary vane vacuum pumps to force hot air and water through tightly packed espresso grids by pressurizing the fluid entering the pump suction at higher than atmospheric pressure. Soda dispensers also often use rotary vane vacuum pumps to move water into pressurized CO2 tanks.
