What is the function of the intra-vane in a vane pump?

The function of the intra-vane within a vane pump is primarily to regulate vane wear. In a vane pump, the intra-vane is positioned between the vanes and the pump casing. As the pump operates, the intra-vane helps to maintain a consistent pressure on the vanes, which prevents them from wearing out prematurely. This design allows for a more efficient operation and extends the overall life of the pump by ensuring that the vanes can move freely and maintain a good seal against the pump casing.

Understanding the role of the intra-vane is crucial, as it directly affects the performance and reliability of the vane pump. By effectively managing how the vanes interact with the pump casing, the intra-vane minimizes friction and wear, which can lead to improved efficiency and reduced maintenance costs over time.
