Just been browsing through the Tunze page and came across this product:
I like both sides of that. The first is that if you have a warm climate you can be run on any DC source, such as from a wind turbine or solar cell. This actually has me wondering whether you could recover some of the energy from the sump return pump by installing a water turbine on the drain and use that to generate electricity to drive the tank's flow (you would be saving very little on a pump which uses from 4-18W, but every little helps).
The alternate use (which again is nice) is the ability to connect up a redundant emergency power supply (example used is a car battery) which is used when the mains power us cut off. If this is capable to charge a battery then it would be amazing for anyone worried about power cuts.
This, to me, is a huge advantage of using DC pumps, it seems strange that so few companies (if any) are using DC pumps.
Other power supply units for Turbelle® nanostream® 6055 - safety connector.
Turbelle® electronic 6055 has been fitted with an electronic motor. The pump can be operated on any direct-current source (battery, solar cells) from 10 V to 24 V. For a safe connection to the pump, we recommend the Turbelle® Safety Connector 6105.50, which contains a 4 amps fuse. The safety connector permits normal operation with the TUNZE® power supply unit, but in case of a power failure it will automatically switch over to a car battery or a direct-current source.
