I'm not clear what your request is for. The Slowpump was
originally developed for just such an application as you have
described. The principal limitation is that it has to be
fine-filtered on the intake side, to protect the precision
positive displacement pump head. That's why Dankoff Pumps offers
the 30" filter/foot valve intake kit.<br>
<br>
If you are simply wanting a motor that will work PV direct, the
Slowpump motor will do that. My own experience over many years is
that the MET motors used in the Slowpumps and Booster Pumps almost
never need brushes replaced (and they're available if ever
needed). So can you explain why you're looking for a brushless
motor?<br>
<br>
Thanks, Allan<br>
