Executive 56 Frame 5 hp Spa Pump

The Waterway Plastics 3722021-1D is a 230-volt pool accessory designed for hot tub circulation. It suits owners who need a replacement pump with a 56-frame motor rated at 5 hp. The unit delivers a 220 Gallons Per Minute flow rate through a highly versatile wet end.

Two-speed 220 GPM upgrade

This pump replaces single-speed models when variable flow control is required for filtration and jet operation. The 2 Speed motor allows lower energy use during circulation cycles. The jump is worth it if the existing wet end orientation does not match plumbing and a 90 Degree rotation solves alignment.

56-frame motor and 230-volt supply check

Verify that the electrical supply provides 230 volts and that the control system supports two-speed operation. Confirm the mounting footprint matches a 56-frame motor and that the plumbing connections align with the rotatable wet end. The Viton Shaft Seals are rated for standard spa chemistry.
