Brilliant
idea! Ready made piston head, pump body, and that can take a lot of pressure!

What pressure can you reach with this setup?

In China,Buy a refrigerator compressor to $ 70
You can remove one from an old fridge

Brilliant idea! Ready made piston head, pump body, and that can take a lot of pressure
so it seems... not a bad idea




If the transformation is well
Could you explain how to 'transform' it?
(how to modify it into a pump)

Seems fairly simple - drill a hole in one end and add a check valve.

Yup... you want to find one with a relatively small inner diameter (sub 0.75") and long stroke to be a useful pump. Or you can get that fridgy working ;)
