Vacuum pump DC 12V 12W, micro diaphragm pump air compressor -75KPA vacuum degree 12LPM flow

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.

I used this at nine volts instead of the rated twelve volts. It still had a lot of suction, and it was quieter.

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.

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.

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.

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 like the pump but need to know I it’s life expectancy in the following scenarioWe are a new company that uses a pump to evacuate urine from an external male catheter and discharges it through its outlet. The pump needs to create a vacuum of 75 kp on a continuous basis only interrupted briefly by liquid flow of about 200 ml during urination.Typically the pump would operate about 3000 hours per year, primarily as a vacuum pump, but with as many as 1500 brief liquid pumping events during the year. We would like it to last several years.

Was to small, needed more vacuum for my wiper motor
