Jandy FloPro (single- and two-speed)
Jandy's compact single-speed. The small DOE-compliant sizes are still sold; the 1.5 HP and up stopped in 2021.
0.95 THP (FHPM.75) · 1.24 THP (FHPM1.0) · 230/115V (230V on the two-speed) · single-speed
What we repair on the Jandy FloPro (single- and two-speed)
An induction motor with a start capacitor. The capacitor, the seal and the bearings are the usual failures — all repairable on the spot when the part is on the truck.
- Hums but will not start — usually the start capacitor, sometimes a seized shaft
- Trips the breaker or overheats — motor windings, wiring, or a failing bearing
- Leaking at the shaft seal (water under the motor) — a new mechanical seal before the bearings rust
- Air in the basket and losing prime — lid o-ring, basket, drain plugs, suction-side unions
- Loud grinding or screeching — worn motor bearings
- Low flow — impeller clogged or worn, diffuser gasket, basket
- Cracked strainer housing, lid or basket
From Jandy's manual
- The start capacitor sits toward the backplate handle when the motor is refitted; motor bolts 15 ft-lb, backplate screws 10 ft-lb.
- Uprated motor replacement kits R0479301–R0479314 cover SHP, PHP, MHP and FHP pumps.

If it is time to replace it
Repair first when it makes sense. When the housing is cracked, the motor is failing on an old single-speed, or the parts are no longer made, these are the pumps to look at:
Jandy VS FloPro (115/230V)
Jandy's compact variable-speed pump, sized to replace a single-speed of up to 1.5 HP. It runs from a controller or automation, not on power alone.
1.30 THP · 1.65 THP · 1.85 THP · 115/230V, auto-sensing
Specs, repairs & install →Jandy names it as the replacement.
Jandy VS FloPro with 2 Aux Relays
The larger VS FloPro, with two programmable relays of its own. Jandy sizes the 2.7 to replace single-speeds up to 2.5 HP and the 3.8 for pumps up to 3.95 HP.
1.85 THP · 2.70 THP · 3.80 THP · 115/208-230V (1.85, 2.70) · 208-230V (3.80)

Why a replacement pump is almost always variable-speed now
- Since July 19, 2021, new pool filter pumps have had to meet a federal Department of Energy efficiency standard. For the common in-ground size — a single-phase, self-priming pump of about 1.15 motor horsepower (0.711 hydraulic horsepower) or more — DOE says that standard would likely require a variable-speed motor. (10 CFR 431.465)
- Since September 29, 2025, new pool pump motors from 1.15 to 5 total horsepower must be variable-speed — including a motor sold on its own to replace a failed one. Once older stock is gone, a worn-out single-speed motor of that size is replaced with a variable-speed one, not another single-speed. (10 CFR 431.485)
- Smaller pool pump motors (0.5 to under 1.15 total horsepower) must be variable-speed when made on or after September 28, 2027; DOE has said it will not seek penalties on those small motors made before March 26, 2029. (DOE enforcement policy, April 2026)
- ENERGY STAR still certifies pool pumps; EPA says certified in-ground models use about 20% less energy than standard ones. (ENERGY STAR pool pumps)
