The Different Classifications of Vacuum Pumps
The Different Classifications of Vacuum Pumps

When it comes to finding the right rotary vacuum system for your needs, GlobalVac can assist you in the right direction. Here is a brief introduction to the various types of vacuum pumps for your facility.


Rotary vane pump- This classification of pump is designed to handle fluids with a low to moderate viscosity. This means that this system can only handle fluids up to a certain amount of thickness, but it can handle large volumes of viscous fluid at a high speed.

The rotary vane pump consists of a rotor that has a various amount of vanes mounted onto it, the rotor rotates inside of a cavity. Depending on what the pump will be used for the vanes can vary in length and tension. These pumps can be used in a large variety of applications, from braking assistance in large trucks to evacuating refrigerant lined in vacuum experiments in physics. If you’re looking for a high quality rotary vane pump, you can learn more here.


Rotary Vane Vacuum Pump - This type of pump can work with fluids of varying viscosity. As a result, these systems can be useful in pumping low viscosity fluids such as oil and gas to highly viscous ones such as rubber compounds. The structural design of the gears allows for continuous pumping and flow.

The rotary vane vacuum pump is also able to work with varying temperatures in addition to the different levels of fluid viscosity. This system offers bi-directional rotation, meaning that it is highly effective in loading and off-loading fluids from a reservoir without the need to change the position of the pump. 


Oil less vacuum pump - the oil less vacuum pump operates without relying on oil as a lubrication fluid. Dry lubricants such as carbon are used to reduce the friction that is created between the engine’s core parts, this allows the system to work smoothly.

Industries that usually opt for an oil less vacuum pump model will be those that have a sensitive atmosphere where no contaminants can be found in the air, like a kitchen or medical laboratory. Since there are no fluid coolants used, the system is likely to get hot over time resulting in the need to get rid of excess heat.
