Sales people use brake horsepower (Bhp) when rating pumps to deliberately mislead
you into thinking it’s more powerful. Brake horsepower (Bhp) is the horsepower required to apply a stop brake to the pumps electric motor. Continuous flow horsepower (Hpcf) is the horsepower generated by the water pump that is delivered to the spa jets; this is the accepted industry ‘yardstick’. No spa, imported or Aussie made, is currently manufactured with 4Hpcf pumps; they will be 4Bhp which is actually 2.25Hpcf.
Sapphire Spas use 5.2Bhp = 3Hpcf pumps which can be up to 25% more powerful at
the jets than most of our competition.
