Jim- This probably won't be a good idea. Nitrile impellers dissolve in biodiesel in just a few months, standing or in use. While brass is a catalyst for oxidation of biodiesel, yielding a green slime and degraded fuel. The safe impellers are cast iron, plastic or stainless steel.
I'm not overly impressed with the agitation requirements, I've done hundreds of reactions with a 1/12 hp mixer. Recirculation pumps could be a good idea if it is also used as a tank fill or drain pump. Keep up the good work.
