Description
This listing offers a complete Waterway Executive wet end assembly designed for 3 HP spa pumps with 48 frame motors featuring 2 1/2" intake and 2" discharge ports. Your purchase includes everything needed: volute housing, impeller, mechanical seal, seal plate, wear ring, and mounting screws. Frame sizing is determined by motor mounting bolt spacing: 48 frame configurations measure 3 5/8" center-to-center or 5 3/16" measured diagonally in an X pattern, while 56 frame units measure 4 1/8" center-to-center or 5 3/4" diagonally.
This wet end assembly pairs with motors rated at approximately 12.0 Amps at 230 volts. No 3 horsepower spa pump motors operate on 115 volt power.
Important Sizing Note: Standard 2" pump unions typically measure approximately 3" across, however this Executive model features an enlarged suction port measuring roughly 3 5/8" edge-to-edge. Verify your current wet end has this oversized front intake before purchasing.
To identify the correct replacement, locate the amperage rating on your motor label. For dual-speed pumps, you'll see two values (example: 10.0/3.5). Use the higher number. For single-speed motors, one amperage is listed. Reference guide: 8.0A = 1 HP, 10.0A = 2 HP, 12.0A = 3 HP, 14.0A = 4 HP, 16.0A = 5 HP. Critical: Always match by amperage rather than the horsepower stated on your motor label, as horsepower ratings are frequently exaggerated by manufacturers while amperage values remain accurate. Consider the electrical reality: two genuine 5 HP pumps at 16 amps each totals 32 amps, plus a 5.5 KW heater adds 21 amps, equaling 53 total amps—exceeding the typical 50 amp spa breaker capacity. This proves most installations actually use lower horsepower pumps than claimed.
