The power of a motor is
usually measured in "horsepowers" (hp).

Our River pool comes with a standard
Why do they stop at 7.5hp?
Because with a
single phase electrical service (what normally is
available in a household) the biggest motors
reasonably efficient are 7.5hp.
Bigger motors used in the industry are 3-phase
In our design, we chose to use an expensive
electronic device to convert your single phase
service to 3-phase. Thus we can operate a 10hp
3-phase motor without requiring a 3-phase service.
A 3-phase motor is inherently
more efficient, especially when used below its
maximum potential. This translates in MORE POWER
lower cost of operation for
Further design advantages:
We chose to use a big 18" diameter pipe as a return
channel for the water to return to the front of the
pool. This pipe is under the pool bench.
allows for more water to be moved at parity of power
- We also chose to use a centrifugal propeller.
Water pumps are centrifugal, because this is the
most efficient way to move fluids. This allows for
more water to be moved at parity of power used.
- We chose to use a standard industrial electric
motor operating in "dry" conditions and expected to
run uninterrupted for 50 years (as opposed to an
underwater motor). This translates in much lower
costs of maintenance and "more power for the buck".
