Potential for a 10 energy star Pool pump
The Supa-Stelth pool pump with leaf basket is the most energy efficient possible. It has been known for some time that for pools the slower the pump can run the more energy savings there are. The average pool is 50,000 litres (13,000 US gallons), which needs to be turned over twice per 24 hour period. By taking the ‘time’ to do this rather than forcing massive volumes of water through filtrating circuits in 2-3 hours the electrical savings rise by the cube! This is different to ‘wire to water efficiency’ in that the cost in dollars per kilowatt-hours or the real cost of running a pool pump is significantly less.
Our Supa-Stelth pool pump simply does it better. Reason for this: All pool pumps have to be able to run at high speed e.g. 2880 ppm in Australia (3600 rpm in USA) to both prime the pump and run pool cleaners etc. The diffuser or volute in conventional pumps has to be ‘tuned’ for this high-speed operation. The trouble is, as the speeds come down in two and three speed pumps the diffuser acts like a self limiting valve, therefore hindering the performance. The Supa-Stelth pump has no diffuser, volute or cutwater to worry about, therefore maintaining efficiency for longer. Also as the filtration system of a pool gets clogged up with debris and gunk, the very wide efficiency curve advantage of Supa-Stelth comes into play. It keeps up the high efficiency even while the filter is clogging up.
A comparison might be two cars give the same Km/miles per litre/gallon at highway speeds; however only one car delvers excellent fuel consumption at all speeds. Which one should you buy?
This pump is in the process of being adapted to a inexpensive variable speed motor. This motor can operate well above convetional RPM. Only pool pumps operating on SBV can benefit by this. Pumps should be available worldwide by late 2017.
