Vane Pump Animation

The working principle of a vane Pump.

Vane pumps have an internal cylinder that rotates via a shaft from the motor. This cylinder has various slots all the way round that house a series of vanes. As it rotates, the vanes slide in and out of the cavities, this forces the fluid through the pump at pressure.

As this is a positive displacement pump, it can maintain the flow rate regardless of fluctuations in pressure, a common problem when using centrifugal pumps for fuel transfer applications.
