Id like to fit an open impeller pump to my reactor.
Although closed impeller certainly put out some flow, my oil is never filtered well enough, and im sick of unblocking them.
I suspect open impeller maxes out at 80-100lpm, but that's fine with me. Ive resorted to using a tam105 at present, so an upgrade on that is required.
Im too much of a skint flint to think about buying new, so im asking what i should be looking out for on ebay and the like?
Thank you!
