Hi augiedoggy,
How do you pre-filter when using the "little tan" BLDC pumps?
I recently picked up 8 Topsflow TL-B10 (A12-0905) pumps for a good deal with one of the applications being vorlauf and transfer from my mash tun to the BK in what will someday be an automated system. I did not realize until doing some testing that the impeller is very easy to plug with grain, and they don't lend themselves to PWM speed regulation very well. My mash tun is a 10gal orange round cooler with a false bottom. I don't get much grain that passes through, but this tiny closed impeller has zero tolerance. I'm debating going to a grain-tolerant pump if the little BLDC pump is too much hassle or unreliable. Any input is appreciated!
Thanks,
Cam
