Much Ado About Vane Pumps: Specifications And Advantage Of The Machinery

vane pump

A Vane pump is a type of hydraulic pump. Unlike any other hydraulic pumps, this particular pump functions in a very low volume. The lower level of noise produced by the pump is why many continue to choose it. Production of the lower level of noise indicates less pulsation and less pulsation means a smooth transition of the fluid in the directional control valve. 

Vane pumps are thoroughly used because of the efficiency of the functionality for the most part. The vane pump which creates low noise operates with a low pulsation which is known as a constant flow. It creates a sense of commensurate atmosphere where the speed is maintained, the sound is reduced and displacement is retained. 

It is said that the vane pump uses the high-end power of displacement which raises the speed of the fluid in the directional valve system. In this article, we will discuss what the hydraulic vane pump does and its types for your better understanding.  

Tends Types Of Hydraulic Vane Pump: 

There are many variations of the pumps available in the market depending on the functionality and the effect the vane pump produces. Each type of pump has different forms of configuration system with a certain condition disposed upon it. Though the added or rather modified pumps have an external device to support the multifaceted aspect of the function of the appliance, the major function remains the same. 

The main task of the hydraulic pumps is to reduce the level of the sound. By eradicating the excessive sound, the pulsation will become more static and symmetrical. It will create a positive effect on the work. Let’s see what types of “vane pumps” are there


  • Single chamber vane pump: This particular vane pump uses the stroke movement produced by the vane which is restricted by the circular internal track. The stroke ring is placed off-center keeping in mind the place of the rotor. It results in the modification of the sound in the displacement chamber.

    The chambers are structured using rotors, a surface ring, a control disc, and two vanes. The pressure is only placed on the side of the rotor. It creates pressure on the bearing that is why the rotor needs to be balanced to reduce it.


  • Double chamber vane pump: This particular vane pump uses two shafts to utilize the strokes in the rotation. In each stroke, the two shafts are utilized. The radial pressures the rotor which gets neutralized. There are two pressure ports available on both sides.

    Two pumps are structured in a way to resemble one single shaft. This functionality of the twin-cam configuration compels the system to create two displacements per occurrence of revolution. The process of saturating the chambers and emptying it is similar to the first chamber vane pump.


  • Single vane pump: This type of pump has only one cartridge kit. In other words, single vane pumps consist of only one pump cartridge that focuses on the deliverance of the flow of the fluid into the system. 



  • Double vane pump: Double vane pump has two cartridges.



  • Triple vane pump: This particular type of pump has three cartridges. 


Advantages Of Using The Vane Pump:

There are many advantages to using a vane pump. Not only it reduces the noise but creates proportional linearity of fluid production. When it comes to the advantages, they are multifaceted. Let’s see what they are. 

  • This type of pump is self-priming, strong, and delivers one constant result at a given speed. 
  • A uniform discharge of the displacement is maintained throughout the action of the vane pump.
  • The vanes put together in the pumps are self-compensating. As they can be replaced whenever they scrape down.  
  • Vane pumps do not need the employment of any check valves.
  • Compared to any other valves, they are very light in weight. The structure of the product is even compact.
  • The fluid can be vapors or gases. The liquid can surround gases too.
  • Volumetric efficiency is high.  
  • If the viscosity and pressure changes, the discharge remains unaffected.

Most Asked Question On The Internet:

You will find two types of vane pumps in the market. Unbalanced vane pumps Balanced vane pumps
The gear pump takes up the fluid to the destination through the two meshing gears. One gear is used by the shaft. Meanwhile the other turns the idler gear. The vane pumps however reduce the sound of the flow while emitting less pulsation. They are both utilized for a fixed flow of the fluid. Both the pumps use positive displacement to deliver the volume for each cycle of the pumping.
The three types of hydraulic pumps that are widely used are the gear pump, vane pump, and piston pump. Even though there are other types of pumps available too.


A Vane pump is very important to create a sense of symmetry in the working atmosphere. Even though the function of the pumps sounds trivial but the result creates a huge effect on the outcome. The vane pump is almost used as a noise reduction machine that generates a balanced fluid flow to reproduce displacement and energy.
