We are using 24VDC solar power to pump 50/50 glycol-water at remote well locations. We could increase the source voltage to 48V but I'm trying to stay away from anything higher and do not want to go to AC inverters. The calc hp requirements vary from 1/5 to 1/2 hp. They run in a fairly harsh...
We have several hundred pressure vessels that have pneumatic fail close inlet valves that shut in at high pressure. We'd like to add another level of protection so that if the current sensor doesn't react, an independent sensor would see the pressure, close the supply and bleed the diaphragm...
I need to pump 3-6 gpm of 50/50 glycol and water at 15-20 psig for heat tracing production lines. There is no electrical power, so I'm trying to do it with a 24 V solar system and as such efficiency is a primary concern. I inherited a pilot test with solar pannels, batteries, inverter, AC motor...
