Vacuum pump DC 12V 12W, micro diaphragm pump air compressor -75KPA vacuum degree 12LPM flow,Suitable for breast pump parts replacement and vacuum adsorption projects

Not sure if this will help anyone or not. I used this vacuum pump to make a desoldering gun. It has more vacuum than I thought. Works great. The only issue I see is there is no mounting tabs but, I am putting it inside an enclosure so it really doesn’t matter. I used an old vacuum and fuel gauge ( it was the only one I had ) to measure the pressure. Hope this helps someone and I hope everyone is safe and well.

This was perfect for my DIY vacuum pump and dispenser. I was too lazy to keep pumping by hand to vacuum fluid out. Also puts out about 30psi, which is great if you want to small pressure test something and don't want to bring out the compressor.

This is nearly identical to the pump in my wife's Spectra 2 breast pump. After 1200 hours just short of a year the original dies and insurance only pays for one pump in a calendar year. So instead of buying an entire new one for $160 this was a much cheaper option that they dont want advertised. With a little research I figured out this was the pump and amazingly it was on Amazon Prime. So about $25, a few screws and two terminals to solder and that's it. Works like new.

I purchased to make a vacuum sealer for 3D printing filament. This thing really pulls a vacuum some such a small pump. 75Kpa is roughly the suction power of smaller FoodSaver machines, for reference. For another reference, 12 liters per minute is 200 mL per second -- it's faster than you may imagine. It runs reasonably quietly. It appears to be well made and even comes with a wiring harness. The only critique is that there are no mounting options so this baby got epoxied inside a project box. Still, I'm happy with the price.

Decently quiet. Good value for the money. Quality is good. I knew from the pictures and the reviews that this pump did not come with a mount, so I am including a video about my simple solution in case it helps others.

Used to seal reusable vacuum bags for 3D printer filament. Together with a 12V power adapter and vacuum bags from Amazon, clear plastic tubing, and homemade cover it does a factory like job for filament storage. Will revitalize most old filament.

Was to small, needed more vacuum for my wiper motor

This does a great job pulling a vacuum on my filtration setup, the only downsides are the lack of obvious mounting points and that the motor gets pretty warm, so I’ll have to build a cooled enclosure of some sort. Don’t bother using the tubing that comes with it if you’re using it as a vacuum pump though, it’ll suck in on itself, so best to get some thicker-walled tubing.
