Description
This complete Waterway Executive 1 HP Wet End Assembly features 2 1/2" X 2" plumbing connections and 48 Frame mounting. Your purchase includes all essential components: screws, volute housing, impeller, mechanical seal, seal plate, and wear ring for a complete installation. Frame size identification is critical—48 Frame units feature motor through-bolt spacing of 3 5/8" center-to-center or 5 3/16" measured diagonally in an X pattern, while 56 Frame models measure 4 1/8" center-to-center or 5 3/4" diagonally. This wet end pairs with pump motors rated at approximately 8.0 Amps at 230V or 12.0 Amps at 115V operation.
Important Fitting Information: This Executive wet end has an oversized suction port that measures approximately 3 5/8" edge to edge, larger than standard 2" union fittings which measure about 3" edge to edge. Verify your existing wet end has this larger front suction fitting before ordering.
To determine proper horsepower, always reference the amperage rating on your motor label rather than the stated horsepower. For dual-speed pumps, you'll see two amperage values like 10.0/3.5—use the higher number. Amperage-to-horsepower guide: 8.0A = 1 HP, 10.0A = 2 HP, 12.0A = 3 HP, 14.0A = 4 HP, 16.0A = 5 HP. Disregard the horsepower claim printed on your motor and rely solely on amperage, as horsepower ratings are frequently overstated by manufacturers. Consider this: two actual 5 HP pumps at 16 amps each total 32 amps, plus a 5.5 KW heater adds 21 amps, equaling 53 amps—exceeding most spa 50 amp breakers. This proves most spas don't actually contain 5+ HP pumps despite marketing claims. Amperage specifications are accurate and verifiable.
Global offers additional Executive wet end configurations for different horsepower requirements in this same 2 1/2" X 2" 48 Frame platform.
