Great work. Keep it up! :)
I got to measure water volume flow but the method I used was to simply time how long it took to fill a one liter bottle hehehe. Did it around fifteen times just to be able to get an average. The pump would fill one liter a little under 10 seconds which comes out to 6 liters/min or 360 li/hr (95gph). On the other video I posted (IMG 1079), the chamber I added is much higher than this one (pump height same). I was able to get 7 li/min or 420 li/hr (111 gph).What's funny is I forgot to put an air release near the discharge spout. Maybe I'll do one more run with an air release just to see if efficiency increases hehe.
Our IBCs are arriving this Tuesday, luckily I'll be able to do a test run this weekend using the actual specs of our planned aquaponics system design (CHIFT PIST). If I'm able to get solid numbers I'll send you a diagram just in case you'd be interested in building and testing out the pump
Wow nice work. That water is really coming out with some force. I noticed with Glens design he has the up tube go straight into a larger pipe which acts as a collection chamber. perhaps this allows for less restriction pumping around the elbows. That chamber then overflows out of the unit with a pretty even flow. I wonder if that is more efficient at all, or if you would ultimately end up with the flow rate you are at now. Did you get a chance to measure it yet? :) Looks like you might be getting close to 100gph or so.
