Flanges are universal and what will have will work with any brand.
Depending on how your pump is mounted, you probably will have to rotate them 90 degrees. The 0011 is turned 90 from the 007 too.

bigger pump will run alot more water thru exchanger from the outdoor furnace side which in turn your house pumps are running slower thru the exchanger and robbing more heat from outdoor furnace. Also make sure your exchanger isn't hooked up backwards. Im no expert but if your loosing 20# on the return of exchanger why have one what i have noticed when a zone is first calling I would loose fifteen# at most due to the lines cooling off and whatnot while sitting waiting to flow again but after a few seconds its only loosing at most 3# on the return compared to the inlet from outdoor stove.
