Slow day at work. Found some more info. Appears DPW is a DuraPro pump made for
Napa. Some research found that DuraPro is manufactured by GMB. Here is a page
on their high performance pump.

It looks like a well designed pump. The Flowkooler just has the impeller
redesigned, but I don't think they did much else other than make it out of
aluminum. This one appears to be stronger, and redesigned passageways. I amy
see if my local Napa has any in stock that I can physically look at.
