Just tell Ken at MMI that you need a impeller for a Oberdorfer pump. He will fix you up.
Also tell Ken you need a M7 cam shoe to increase the pump's output. P\N CSOB_8_69.
I'll explain as well as I can remember. If Ken or another member says something different go with what they say.
Anyway: The Oberdorfer pump comes with a 5 millimeter cam. Increasing the cam to 7 mm compresses the impeller blades more resulting in more pump output.
