The vane pump uses positive displacement with a rotor and vanes to force liquid through pipes. It creates small chambers within the larger cavity to move liquid and maintain uniform flow. It’s used in automobiles, food service, and processing of liquids or gases.
The vane pump is a device that works on the principle of positive displacement. Consisting of a series of vanes mounted on a rotor that provides circulation with the main cavity, the vane pump allows liquid to be forced through a system of pipes or ducts at the speed desired by the operator.
In most examples of the vane pump, the vanes slide in and out of the rotor as the device operates. This combination of actions creates a seal within the cavity and effectively forms a series of small chambers within the larger chamber. Liquid is captured in each of these chambers and is forced through the system by the resulting pressure of the rotation. Essentially, there is atmospheric pressure on the suction side of the pump which helps draw in the liquid, while the pressure created by the rotary action helps move and discharge the collected liquid from the suction or discharge side of the pump. The rotor helps maintain uniform liquid flow throughout the process.
A vane pump can be used in different settings. When it comes to use in automobiles, pumps of this type are often used to move transmission fluid through the system, as well as power steering fluid. In food service settings, a vane pump provides the pumping action that will move carbonators in specific quantities through soda dispensers and coffee machines.
A variant of the vane pumps used in the processing of liquid substances are models that deal with the movement of air or some kind of gas. Hydraulic braking systems on diesel vehicles use this type of pump. Clearing refrigerant lines in air conditioning equipment is a task that often involves a vane pump. Whether it’s in manufacturing, agriculture or even around the home, the vane pump can be used for many different applications.
