The Aqua-Flo Flowmaster XP-2 has many spa and hot tub applications. The pump union connections line up directly in previously installed Waterway Super-Flo Spa Pump applications such as Cal-Spas and others, which is especially important where hard pvc (non-flex) connections require almost perfect alignment. This pump wet end is also very popular in later model Watkins Hot Springs Spas.
To complicate things a little Aquaflo makes 2 56 frame XP2s of slightly different diameter. Look on your existing pump in the area where the motor thru bolts connect to the wet end. If you have a number 92770715 you need the 6.1 inch diameter. if the number there is 92770725 you need the 6.3 inch diameter.
