What are Vane pumps

Rotary vane pumps are a very popular form of positive displacement pump that have been used around the world for many decades. They consist of vanes mounted on to a rotor that rotates inside the pump chamber. In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates.


  • Self priming.
  • Consistent flow.
  • A choice of mechanically sealed or mag drive vane pumps.
  • Develop a good vacuum.
  • Can handle thin liquids at relatively higher pressures.


Rotary vane pumps are used in many different applications due to their all round versatility. They can deliver flows up to 450 m3/hr and differential pressures of 14 bar.  They are typically found in dispensing applications, transferring fuels, low flow circulation duties and some specialist applications such as pumping chocolate.

Rotary Vane pumps are also commonly used for pumping viscous fluids such as oils and syrups, as well as this Vane pumps can are excellent at handling a varietyt of solvents such acetone. 


AxFlow UK has been supplying rotary vane pumps for over 50 years as a result we are one of the leading experts when it comes to rotary vane pumps in the UK.

AxFlow offers 10 different ranges of vane pumps from three manufacturers; Blackmer,  Gruppo Aturia,  and Mouvex giving us the widest selection of vane pumps in the UK. Our range of vane pumps includes cast iron and stainless steel models, mag drive options, vane pumps designed for low viscosity liquids such as LPG, API 676 and pulseless pumps.

Vane Pump Maintenance 

The most significant parts of a rotary vane pump when it comes to maintenance are its vanes. As the vanes run against the internal pump chamber walls they will wear over time.

The rate of wear depends upon the following factors:

  • Running speed ie the faster this is the higher the rate of wear.
  • The viscosity of the liquid, the thinner the liquid the quicker the rate of wear will be.
  • How many hours a day does the pump operate.
  • Dry running which will again wear the vanes away.
  • The presence of abrasive particles.
  • Materials of construction of both the vanes and the surfaces they are running against.

Because of the range of parameters the maintenance requirement will never be the same but a scheduled dimensional check of the vanes should always be undertaken.

Many vane pumps are fitted with pressure relief valves these should be checked on a regular basis.

In addition to the above, and depending upon the specific construction, components such as bearings, mechanical seals and electrical performance should always be checked on a regular basis.

How to select Vane Pumps

When selecting a rotary vane pump, a range of factors should be taken into consideration in order to ensure that it meets your specific needs and application requirements. Here are three key factors to consider:

  • Flow Rate and Capacity: Determine the required flow rate and capacity for your application. This involves calculating the volume of gas or fluid that needs to be pumped per unit of time. Make sure the rotary vane pump you choose can handle the necessary flow rate without excessive backpressure, which could affect performance.

  • Vacuum Level or Pressure Range: Different applications require specific vacuum levels or pressure ranges. Consider the required vacuum level (e.g., deep vacuum, high vacuum, low vacuum) or pressure range (positive or negative pressure) that your application demands. Ensure that the selected rotary vane pump can achieve and maintain the desired level within your application's operating conditions.

  • Chemical Compatibility and Material Selection: Evaluate the compatibility of the pump's materials with the gases or fluids you will be handling. Some applications may involve corrosive or abrasive substances, so it's crucial to choose a pump with materials that can withstand these conditions. Pay attention to the materials used for the pump housing, vanes, seals, and other critical components.

Additional factors to consider might include:

  • Pump size and footprint: Ensure the pump fits within your available space.
  • Noise level: Consider noise regulations and the impact of pump noise on your work environment.
  • Maintenance requirements: Assess the ease of maintenance and availability of replacement parts
