This is a Waterway Executive 115V 1 .5HP 48fr 2 1/2" x 2"..

This pump is a very unusual one as it has a 2 1/2" Suction Side which measures about 3 5/8" edge to edge on the threads on the front suction side and 2" on the pressure side top which measures about 3" edge to edge..

Note: I have seen this pump in Phoenix brand Spa Titanium series with a 56fr sticker on them but it is definitely a 48 frame..
