Description
This complete 2 HP Waterway Executive wet end assembly features 2" x 2" plumbing connections and 56 frame motor compatibility. Your purchase includes everything needed: volute housing, impeller, mechanical seal, seal plate, wear ring, and mounting hardware.
Frame Size Identification: The 56 frame design uses motor through-bolt spacing of 4 1/8" center-to-center, or 5 3/4" measured diagonally in an X pattern. This differs from 48 frame units which measure 3 5/8" center-to-center or 5 3/16" diagonally.
Correct HP Identification by Amperage: This 2 HP wet end matches pumps drawing approximately 10.0 amps at 230V or 16.0 amps at 115V. For accurate sizing, always reference the amperage rating on your motor label rather than the horsepower rating. On dual-speed motors, locate both amp ratings (example: 10.0/3.5). Use the higher number for sizing. Amperage guide: 8.0A = 1HP | 10.0A = 2HP | 12.0A = 3HP | 14.0A = 4HP | 16.0A = 5HP.
Why Amperage Matters: Motor horsepower ratings are frequently overstated by manufacturers. Electrical current draw doesn't lie. Consider this: two pumps at 16 amps each (32A total) plus a 5.5kW heater (21A) equals 53 amps—exceeding most 50-amp spa circuits. This proves most residential spas don't actually contain 5HP+ pumps despite marketing claims.
This Waterway Executive series wet end provides reliable performance for spa circulation and jet systems requiring 2 horsepower output with 2 inch suction and discharge ports on a 56 frame motor mount.
