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 variety 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.

How to select Vane Pumps

When selecting a rotary vane pump, a range of factors should be taken into consideration 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.

There are several types of rotary vane pumps which include:

  • Flexible - vanes keep contact with the rotor walls, trapping liquid as the vanes rotate
  • Sliding - vanes slide in and out to flow liquid in through the inlet port into the chamber
  • External - vanes are fitted into the pump’s casing instead of the rotor
  • Oscilating - vanes draw in liquids using a oscillating pumping motion
  • Rotating - vanes rotate inside the cavity which traps the liquid
