I have an existing solar pump setup used for livestock watering that doesn't work correctly - it overflows the trough regardless of what float valve setup I have tried. Since the trough is located at some distance from the well, and it is moved periodically I would like to implement the ON/OFF control using pressure feedback from the float valve, rather than running extra wiring (and trenching) for a level switch. I'd like some advice on adjustable switches that can accomplish this, as the pressures involved are pretty low.
The system uses a SHURflo 9300 submersible pump and Best Pump Controller LCB 902-200. That provides for shutoff if the shallow dug well runs dry and on high pressure.
It pumps very slowly, maybe 2gpm, from the well into a small bladder tank set at 15psi, and from there through a 1500 ft run up to a trough. What I was sold as part of this "package" system to do this was a private label Micro Pressure switch, SPDT, which activates on increasing pressure. But what happens is the float closes very slowly and it overflows the trough somehow, wasting the little bit of water that is available there.
I think I need to alter it with two p-switches - a high pressure OFF and a low pressure ON. This is how it is done on every domestic well setup I've ever been around. But the trick is I need DC switches - and ones that I can reliably adjust for setpoints that are only like 5-20psi.
Any advice on this would be greatly appreciated - thanks.
