  • I have just come across the Solar Pumps out of Germany.

    These would have to be the most energy efficient there is now power usage.

    Any feedback on them.

    • Got a link to the site Norman?

      I can publish some data another time but my last installation looks like we are moving around 15m3 (3962 US gallons per hour) for about 95w Is this a record?

  • Hybrid (http://www.hybridpumps.com) beats them all, in my opinion. 

    • Well the advert says they do.............They use VFD drives to AC motors so cannot be as efficient as DC permanent magnet motors can they?  Have you got any real installation flow vs power figures?

  • Are you looking for purely energy efficiency or are you considering cost-of-ownership; including reliability, serviceability, and parts support?
