Main Question or Discussion Point

I need to pressurized argon gas from 1 bar pressure to 2 bar pressure. Flow rate outlet is 0.5 LPM. Can anybody suggest me a pump or compressor which is small in size? Minitiarised diaphragm seems good option but is it right one?

Welcome to PF.
What temperature range for operation?
Is cleanliness or contamination of the Ar a problem?

Do you require a constant flow rate or a regulated pressure in a reservoir tank?
Compressed argon is used as a shielding gas for welding.

Please give a link to the best pump you have yet found.
You need to know if anyone can see a problem with your selection, or can suggest an improvement.
How small is small?
What power supply is available?

The smallest pump that might do the job could be a peristaltic pump. They are widely available on the web.
