    Balboa Pumps marked "4HP" & "3HP" are actually a 2HP pump in Australian spas. See notes below for explanation. 

    These are a very common pump found on many Spa Industries' brands of spas. (Bullfrog, Signature, Leisurite, Designer, Lanark, SCS Industries, etc)  They were often 2-speed pumps with the low-speed wire clipped off, thus actually becoming single speed pumps. If your plug has one wire clipped off, ensure the new pump has the same done!

     Important Notes: 

    • Some Spa Manufacturers use a complicated & confusing form of Horsepower measurement that was more commonly used in the USA, called hydraulic horsepower (HP=PSI*GPM/1714). It gives a more impressive appearance, and may give a false impression of performance. 
    • Australian HP ratings are calculated purely on input power in Watts, which are then converted to HP. (1HP=745.7Watts). 
    • Balboa & Aquaflo have both released pumps to spa manufacturers that use these confusing power ratings at the request of Spa Manufacturers. 
    • You can always look at the input ratings and convert back to real HP.
    • Rough HP measurement can also be calculated using Ohm's Law (V=IR).   These pumps also have an Amperage rating that can be roughly converted back to Watts, and then to Horsepower.
    • Furthermore, HP ratings are not an ideal measurement of pump performance anyway! Pump flow curves, which measure flow per metre of head pressure are a far more reliable method of measuring pump performance, especially with the advent of variable-speed DC motors.
