Pressurizing Argon Gas: Pump or Compressor Options?

In summary, the person is looking for suggestions for a small pump or compressor to pressurize argon gas from 1 bar to 2 bar, with a flow rate of 0.5 LPM. They mention the possibility of using a miniaturized diaphragm, but are unsure if it is the right option. They also have questions about temperature range, cleanliness/contamination, flow rate vs. pressure, and power supply. They mention using compressed argon as a shielding gas for welding and ask for recommendations for a small pump, preferably a peristaltic pump.

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.
 

1. How does pressurizing argon gas differ from other gases?

Argon gas is a noble gas, meaning it is non-reactive and does not readily mix with other gases. This makes it more difficult to compress and requires specialized equipment.

2. What is the purpose of pressurizing argon gas?

Pressurizing argon gas is necessary for many industrial processes, such as welding and metal fabrication. It can also be used as a shielding gas in certain applications.

3. What are the options for pressurizing argon gas?

The two main options for pressurizing argon gas are using a pump or a compressor. Pumps are typically used for smaller scale applications, while compressors are better suited for larger volumes of gas.

4. How do pumps and compressors differ in terms of pressurizing argon gas?

Pumps use mechanical or electrical energy to move gas molecules and increase pressure, while compressors use mechanical energy to decrease the volume of the gas and increase its pressure.

5. Which option is better for pressurizing argon gas?

The choice between a pump or compressor depends on the specific needs of the application. Compressors are generally more efficient and better suited for larger volumes of gas, while pumps may be more cost-effective for smaller scale use.
