I am curious how to handle this scenario. I have a diaphragm pump pushing water from my tank into my co2 effluent in port. This causes enough pressure to push the water back into the tank. Unrestricted, the flow rate is far too much. So I have been using the included valve to try and "tune" it.
However my problem is that it isn't sensative or accurate enough. It feels like if I bump the dial on the flow restrictor, it will change the amount that comes out.
So I know people are using things like hospital (peristaltic) dose pumps. But my question is given the pressure of water in the return line. How does the peristaltic pump handle that? Aren't peristaltic pumps "pull" rather than "push"? How do you guys handle this?
I am using the Avast diaphragm pump to drive the effluent if that helps. I tried a maxijet 1200, and it just wasn't enough to drive the head pressure. My reactor is about 40 feet away due to space constraints and WAF.
