The Waterway 5 Hp Executive Series complete 56 Frame wet end has 2.5" intake and 2" discharge. Everything you need to replace your old wet end is included. Complete Wet end includes the volute, seal assembly, impeller, wear ring, volute o-ring, suction cover, drain plug and suction screws.
Pump works well although the seal leaked for the first 5 minutes before sealing. It kind of took me by surprise and had me worried and then, it stopped leaking.
Pump a bit noisy,,works fine tho.
