Setting up a secondary expansion tank for my compressor

[jmilch]

Greetings guys and gals, this forum has been a huge help

I just picked up one of these:
Puma 7.5-HP 80-Gallon (Belt Drive) Two-Stage Air Compressor (230V 1-Phase) for a great price locally. It is used but functions excellent.

The pump and motor are rated at 100% duty cycle, so it should be up to the task of filling both tanks when needed.

I have a 80 gallon Quincy horizontal tank that is now extra.(ASME 200 PSI rated, it originally had a 2 stage 175 PSI Quincy QT10 compressor pump installed, but now its just the tank, check valve, and pressure guage.

The Quincy tank has a 1" inlet on top, with a check valve still in place (if I need to use it) and 2 x 1/2" outlets on each side of the tank. It also already has casters I installed, so moving it around is simple. It also still have a pressure guage (300 PSI) installed on it.



So basically I am asking what flexible hosing and fittings I would need that are rated for the PSI this pump will be exerting. I already have the plumbing figured out as far as how the thank will share the air.

Thanks in advance for the help

In all honesty, I don't think you really need it. Setting up an aftercooler or something else would probably work better. I set up an expansion chamber with 2" pipe out of my compressor, but will also be using an aftercooler.

If you are going to plumb it as a non-permanent tank, it would be easier to just daisy chain it after the puma. Just use some short whips with disconnects. I'm guessing the Puma is a 3/4 out, so just reduce the 1" inlet down and then come out of the side with a quick connect.
