Hello, we have just had these made in the Grundfos factory. We have had many enqiries over the years for a decent HD flow switch so here it is...
As you know, Grundfos has the best name in pumps in Australia so it it as good as you can get.
This is a 1/2inch to 1/2 inch brass fitting flow switch to turn your pump on and off when you use the tap.
It is rated at 12v to 24v low amperage. (We have others for deep well pumps up to 10 Amps.)
Just put this in series with your pump on the output side and connect the wires in series with your battery or solar panel..
Then you turn the tap off, this flow switch will turn the pump off within seconds. Turn the tap on and this flow switch will turn the pump back on. easy as that.
Any questions, please call me on 08 95711936
This is a new ebay site but we have a small farm supply site which has been running since 2006 with a 99.7% feedback over 5823 sales.
So we are not new to ebay and I hope we can help you with all low voltage switches, timers, Day/night switches, solar pumps, Solar gates, etc.
