Vane pumps represent one of the most used industrial pump models today, highlighted by its great durability and countless applications, as well as other interesting advantages. Do you need to renew your company’s equipment or are you thinking of acquiring a new pump to modernize your business? Do you know the different types of vane pumps that you can currently find in the market? In this article, we tell you everything you need to know about vane pumps, from their operating principle to the different types and uses within the industrial field.
How does a vane pump work?
Vane pumps belong to the category of volumetric pumps, which also includes widely used industrial pumps such as peristaltic pumps or hose pumps. Basically, vane pumps are composed of a stator or cylindrical space, which houses inside a smaller diameter rotor, with rotating vanes, located eccentrically with respect to the stator.
When the pump is operated, the kinetic energy generated by the motor torque is transformed into hydraulic energy through the generated flow. The working volume of vane pumps can be controlled through the eccentricity of the rotor with respect to the stator: the lower the eccentricity, the lower the supply of the pump, keeping the number of revolutions constant.
What advantages do vane pumps offer?
- Vane pumps are capable of working with all types of fluids, from viscosities of 0.5 to 2,500 Cps, or fluids with solid particles in suspension.
- These types of pumps are self-priming, a very interesting quality for industrial uses.
- A vane pump can work with flow rates of up to 2,400 liters/hour and discharge pressures of up to 18 bar, always offering a constant flow rate and without pulsations, with a wide variety of flow rates available.
- Its gentle treatment of the product, without the need for compression, makes them very suitable industrial pumps to work with products sensitive to cutting or especially delicate.
- These equipment are very compact, with relatively small dimensions taking into account the powers they develop.
- Thanks to its simplicity of design, with a single moving part, vane pumps can offer excellent durability, with very simple maintenance.
What type of vane pump do you need?
Within this category of industrial pumps, we find very different models: non-compensated, compensated, flexible, unbalanced or eccentric shaft vanes, sliding, oscillating, cam and vane vanes, with single or double vanes … Each. They have their own particularities and recommended uses, so if you are thinking of purchasing one of these industrial pumps, it is essential to choose a model suitable for your operational needs.
The compensated vane pumps, for example, only work with fixed flow rates, while if you need a vacuum pump, the most suitable option will be a cam and vane pump. What type is the best choice for your activity sector? If in doubt, your trusted industrial pump manufacturer is the most qualified professional to advise you on the different options available and help you find the most convenient solution for your particular case.
