Description
This comprehensive Waterway Executive 1 HP 56 Frame 2" X 2" Wet End Assembly arrives complete with everything needed for installation: Screws, Volute, Impeller, Seal, Face Plate, Wear Ring, Bleeder Barb, and Silicone.
The included Bleeder Barb substitutes for one of the standard plugs, allowing easy reconnection of your existing 3/8" bleeder hose from your original pump configuration.
Frame Identification: Distinguishing between 48 and 56 Frame wet ends depends on motor through-bolt spacing. For 56 Frame units (like this model), bolts measure 4 1/8" apart or 5 3/4" in an X pattern, while 48 Frame versions measure 3 5/8" apart or 5 3/16" in an X pattern.
Amperage Compatibility: This 1 HP wet end pairs with motors drawing approximately 8.0 Amps at 230V or 12.0 Amps at 115V. Check your motor label for amperage ratings—for two-speed pumps, you'll see dual values like 10.0/3.5 (high speed listed first).
Critical Note on Horsepower: Always rely on amperage rather than the horsepower listed on your motor. Industry specifications often exaggerate HP ratings, but amperage provides accurate performance data. Reference guide: 8.0A = 1 HP, 10.0A = 2 HP, 12.0A = 3 HP, 14.0A = 4 HP, 16.0A = 5 HP. Consider this: two actual 5 HP pumps (16A each) plus a 5.5 KW heater (21A) would require 53 amps—exceeding most hot tubs' 50 amp breaker capacity. This math confirms most systems don't actually contain the horsepower originally claimed.
Additional wet end configurations in this Executive series are available for 1 HP standard and 2 HP applications, all featuring 2" X 2" 56 Frame specifications.
