The vane pump is one of the most widespread fluid transfer equipment in the industrial field. Its high suction power, maintaining a constant flow rate and without pulsations, its reliability and its ease of maintenance are just some of the advantages offered by these industrial pumps, which are very versatile in terms of their applications.
Next, we will tell you how these volumetric pumps work, their different types and their recommended uses.
Vane pump: principle of operation
The vane pump falls within the category of rotostatic volumetric pumps, whose operating principle is based on hydrostatic, like the peristaltic pumps of Boyser. Basically, this type of industrial pump is composed of a rotor with sliding vanes, which moves inside a cam ring or stator, located eccentrically with respect to the rotor axis.
By rotating this axis, a displacement chamber or span is created between the blades, rotor, and housing. As the size of this chamber increases, the generated vacuum forces the fluid into the pump. On the contrary, when the displacement chamber is reduced, the fluid is propelled towards the discharge zone.
Vane pump types
Are you thinking of renewing your business with a new industrial pump? The current catalog of vane pumps has very different models, which will be very useful to know to choose the solution that best suits your needs. If we take into account the flow rate, we can classify these industrial pumps into two main types:
- Fixed displacement vane pump, in which the flow rate and speed are kept constant throughout the entire pumping cycle.
- Variable displacement vane pump, in which it is possible to modify the cause by altering the geometry of the pump displacement chamber. This variation is achieved by moving the cam ring towards the center of the pump, so that the pumping reaches the required values.
In addition, depending on their operation, we can also differentiate between balanced or unbalanced vane pumps, or single and multiple pumps, in which the different elements are mounted in tandem on the pump shaft.
Advantages, uses and applications of vane pumps
What are the main advantages of the vane pump? This model of industrial pumps stands out for its reliability, with very simple maintenance. Wear between the housing and the vane ends is automatically compensated by adjusting the vane ends to maintain contact with the pump housing.
The vane pump is also an excellent option if you are looking for equipment with great suction power, capable of working with both small and large flow rates, up to 2.400 liters / hour, and reaching impulse pressures of up to 18 bar.
Regarding its applications, for which sectors is the vane pump most suitable? These volumetric pumps are excellent for ultrafiltration, reverse osmosis, sprinkling or fogging jobs. Its performance also makes the vane pump an ideal option for fuel injection, lubrication, cooling systems and solar heating. In addition, like the hose pump, a vane pump is also a magnificent dosing pump, widespread within sectors such as the chemical or food industry.
