Description
This complete Waterway Executive wet end assembly is designed for 2 HP applications with 48 frame motors and features 2 inch by 2 inch plumbing connections. The comprehensive kit arrives with everything needed for installation: volute housing, impeller, mechanical seal, face plate, wear ring, mounting screws, silicone sealant, and a bleeder barb fitting for attaching 3/8 inch bleeder tubing.
Understanding 48 Frame Specifications: The 48 frame designation refers to motor through-bolt spacing, which measures 3 5/8 inches center-to-center or 5 3/16 inches when measured in an X pattern. This differs from 56 frame units that have 4 1/8 inch spacing (5 3/4 inches X pattern). This wet end is compatible with motors drawing approximately 10.0 amps at 230 volts or 16.0 amps at 115 volts.
Determining Correct Horsepower: Always verify your pump's horsepower by checking the amperage rating on the motor label rather than relying on advertised horsepower claims. For dual-speed pumps, you'll see two amperage values (example: 10.0/3.5) - the higher number represents high-speed operation. Use this amperage guide for accurate horsepower identification: 8.0A = 1HP, 10.0A = 2HP, 12.0A = 3HP, 14.0A = 4HP, 16.0A = 5HP.
Why Amperage Matters: Horsepower ratings are frequently overstated by manufacturers, but amperage specifications are exact and verifiable. Consider that two genuine 5HP pumps would draw 32 amps combined (16A each), and adding a 5.5kW heater (21A) would total 53 amps - exceeding typical 50 amp spa circuit capacity. This calculation demonstrates why most residential hot tubs cannot actually accommodate the horsepower ratings often claimed.
This Waterway Executive wet end is available in multiple horsepower configurations (1HP through 5HP) with identical 2 inch x 2 inch connections and 48 frame mounting patterns to accommodate various motor specifications.
