Just went to install these in my KE 2 stage pumps. They appear to be smaller in diameter and when installed, the vane does not touch the housing at the point where the center shaft is farthest from the housing. Are they supposed to be this way? I would think not. It's part # 2000. Vanes also appear to be much more flexable...could they cavitate at high RPM? Anyone have any experiance with these and seen this? Thanks.

There was a thread a while back where a factory rep chimed in.
