Aqua-Flo Flo-Master FMHP complete pump assembly engineered for portable spas. This dual-speed circulation pump features a 48Frame 230V motor paired with a 2.0 HP wet end configuration. Both inlet and outlet connections are 1-1/2" x 1-1/2" and measure approximately 2 5/16" across the threads.
High speed operation draws 8.5 amps while low speed operates at 2.8 amps, providing efficient circulation options for your spa system.

Identifying Your Pump Frame Size and Horsepower
Frame Size Identification: Measure the width of your existing motor housing to confirm frame compatibility. A 48 Frame motor measures 5 3/4" wide across the back panel, while a 56 Frame measures approximately 6 1/2" wide across the back panel.
Determining Horsepower on 230 Volt Pumps
Locate the amperage rating on your motor label. For dual-speed models, you'll see two values (example: 10.0/3.5). The first, higher number indicates high-speed amperage and corresponds to horsepower as follows:
8.0 amps = 1 HP
10.0 amps = 2 HP
12.0 amps = 3 HP
14.0 amps = 4 HP
16.0 amps = 5 HP
For single-speed pumps, only one amperage value will be displayed on the motor label.
