I picked up a 110v 12amp motor
attached to a HRO CAT pump and a 40 inch membrane housing plus some odds and ends as far as valves go.
The guy who sold it to me showed me the one he cobbled in his boat. He had a primer pump go through a flow rate and into a 30 and 5 micron filter, oil water sep and then into the main pump. Looks like a diverter which led to his head
sink to test the product before switching it into the main tank. There was a valve (needle??) and then a pressure gauge after the cylinder?
So my question is now, is that just a needle valve that controls the exit pressure? Does anyone have a simple diagram of this? I assume between main pump and membrane I should run hard stainless line to hold the pressure?
I have found membranes super cheap
Order one and a spare I guess?
