Description
This complete 1 HP 48 Frame Waterway Executive wet end assembly with 2" x 2" plumbing connections includes all necessary components: screws, volute, impeller, seal, face plate, and wear ring. Everything you need for a complete wet end replacement.
Identifying 48 Frame vs 56 Frame: The 48 Frame features motor through-bolt spacing of 3 5/8" center-to-center or 5 3/16" measured diagonally in an X pattern. Compare this to 56 Frame dimensions of 4 1/8" between bolts or 5 3/4" diagonally. This wet end is designed for pumps drawing approximately 8.0 amps at 230V or 12.0 amps at 115V.
Critical Horsepower Identification Guide: Check your motor label for amperage ratings. For dual-speed pumps, you'll see two numbers (example: 10.0/3.5). Use the higher number. For single-speed models, use the single amperage listed.
Amperage to Horsepower Reference:
8.0 amps = 1 HP
10.0 amps = 2 HP
12.0 amps = 3 HP
14.0 amps = 4 HP
16.0 amps = 5 HP
Important: Disregard the horsepower rating printed on your motor housing. Always rely on the amperage specification from the motor label for accurate identification. Many manufacturers overstate horsepower ratings, but amperage specifications are factual and reliable.
Electrical Reality Check: Consider this calculation - two actual 5 HP pumps at 16 amps each equals 32 amps, plus a standard 5.5 KW heater adds 21 amps, totaling 53 amps. Most residential hot tubs operate on 50-amp breakers, making true 5+ HP configurations impossible. Trust the amperage numbers, not marketing claims.
This genuine Waterway replacement wet end ensures proper fit and performance for your 1 HP 48 frame Executive series spa circulation system.
