Vane pumps are from the positive displacement pump family, and are suitable for transferring medium viscosity oils, lubricants and fuels at high pressures, and also low viscosity fuels such as alcohol, chemical, fuels and solvents. Most vane pump designs are direct-drive, meaning that there are no transmissions or gears to reduce the speed of operation. Consequently, they benefit from easy maintenance compared to alternative positive displacement pumps. There is no metal to metal contact inside pump, which allows the pump to handle non-lubricating fluids and reduces the amount of wear, ultimately leading to lower life cycle costs.

Vane pumps are often utilised within the following applications:
Edible oil transfer
High temperature fluids (up to 260°c)
There are a number of vane pump designs making it suitable for a vast range of applications. For example, the sliding vane pump has dry-running capabilities and is able to cope with small amounts of vapour, whereas external vane pumps can handle fluids containing large solids.
