Very common impeller in older spas. The horsepower ratings were a bit confusing as some areas use Brake Horsepower, and also North American uses 60Hz power to our 50Hz. Old pumps that were 2hp-2.5hp may be labelled 5HP. Check dimensions to compare. Pump label may have on it's metal tag 1.5kW.
- 115mm Diameter
- 15.5 Vane Width (Inner)
- 6 x Vanes
- May be marked "5HP" on suction throat
New impellers are normally black, and perform / measure the same but look different on the back, and have a small hex in the centre of the throat.
