AquaFlo XP2 2 Speed (Two-speed) Jet Booster Pump - 4.8HP / 2.0HP aka SGS 4.8 BHP. Originally had a black wet-end. Some are sold with black, red, or blue wet-ends. Also sold as SCS Industries 4.8 BHP XP2 Pump. Note that the 4.8 BHP is just a misleading way to rate the horsepower used by some spa manufacturers. 4.8 BHP = 2.0HP
Used on almost all Spa Industries Spas, Signature Spas, Cyclone Spas, Bullfrog Spas, Leisurite Spas, Lanark Spas, Heritage Spas, H20 Spas, Jazzi Spas, Sapphire Spas, and many others!

Notes about Horsepower Ratings:
- 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.
- Standard Australian HP ratings are calculated purely on input power in Watts, which are then converted to HP. (1HP=745.7Watts).
- You can always measure (with an Amp Meter) the input current 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. The problem here, is some spa manufacturers used slightly misleading ratings here as well, eg, they'd use a locked-rotor Amperage draw, etc. You'll see how the Amperage ratings and the HP labels don't match up.
- 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.
- Basically the labels can appear to be very different in regards to the pump's actual HP rating.
Examples: Some Balboa Pumps marked "4HP" is actually a 2HP pump in Australian terms. Some Aquaflo Pumps labelled as 4.8BHP are 2.5HP in Australian terms.
