Leading Edge Of The Impeller

The leading edge is the convex or outward curving part of the impeller vane. (L) in the illustration. The trailing edge is labeled (T)

The leading edge is also the higher-pressure side of the vane in all but a few of the higher specific speed impeller shapes.

Damage on the leading edge of the impeller vane can be caused by a couple of things:

  • Abrasives in the fluid,
  • Internal recirculation or suction specific speed cavitation.
