Description
This complete Waterway Executive wet end assembly is designed for 2 HP spa and hot tub circulation systems with 48 frame motor configurations. The package arrives ready to install with 2" x 2" plumbing connections and includes all essential components: volute housing, impeller, mechanical seal, face plate, wear ring, and mounting hardware.
Frame Size Identification: Confirm your pump has a 48 frame motor by measuring the through-bolt spacing. Proper measurements are 3 5/8" center-to-center or 5 3/16" measured diagonally in an X pattern. For comparison, 56 frame motors measure 4 1/8" between bolts or 5 3/4" diagonally.
Electrical Specifications: This 2 HP wet end assembly pairs with motors drawing approximately 10.0 amps at 230 volts or 16.0 amps at 115 volts. For dual-speed configurations, check your motor nameplate for both high and low amperage ratings (example format: 10.0/3.5, where 10.0 indicates high-speed draw).
Critical Amperage Guide for Proper HP Identification: Disregard horsepower claims printed on motors and rely exclusively on amperage ratings for accurate sizing. Reference these standard correlations: 8.0A = 1 HP, 10.0A = 2 HP, 12.0A = 3 HP, 14.0A = 4 HP, 16.0A = 5 HP. Many spa owners are incorrectly informed about their pump's actual horsepower. Consider this: two genuine 5 HP pumps (16 amps each) plus a 5.5 KW heater (21 amps) would demand 53 total amps—exceeding typical 50 amp spa electrical service. Amperage specifications provide truthful performance data, while horsepower ratings are frequently exaggerated.
This Waterway Executive series wet end is available in multiple horsepower configurations for 48 frame applications, all featuring 2" x 2" port sizing to match your existing plumbing requirements.
