Homemade booster pump test run.

[jmorris]

After some research and looking through my "junk" as the wife calls it, I decided to build a booster pump.

I already have argon and co2 compresses gasses that I weld with, just needed a way to compress that up to higher pressure.

Looks promising so far here is a video of how it works.

I have some 5000 psi check valves and a 68ci 4500 psi tank on the way and I should be able to give it a proper test when they get here.

I like it. Very cool!

I don't know about argon but CO2 turns to liquid at a pressure that is too low to work with, right?

 

[jmorris]

"Co2" for welding is actually a mix of gasses but I will likely just use argon anyway.

The check valves came in the mail a few min ago.

Boy I'm lost......what exactly is this being built for?????

 

[jmorris]

Filling PCP air rifles with what I have at home.

Cheaper than these devices.

How much does the argon cost? Is it really cheaper, in the long run? If you are building a booster pump, would it be that much more difficult to build your own multi stage pump?

 

[jmorris]

I have large argon tanks for all my TIG welding machines and MIG machines setup for aluminum.

I thought about building a shoebox compressor but I already had everything to the one I built on hand except the two check valves and it is much, MUCH less machine work.

It's a section of tubing with an o-ring grove cut inside one end with a single hole drilled into the center of the weld on 1/8 NPT fitting. The piston is aluminum bar stock drilled and tapped with 3 groves cut in it.

$18 and an hour of work if you count a beer break.

love the picture of the gauge pegged! It works!!!


Have you filled your 4500 psi tank yet?

 

[jmorris]

No, it should be here next week.

Nicely done! I learned some things.
