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

Why did you pick this product vs others?:$26.99 and a little wire snipping and soldering and we are good to go. It should be fine to pull what is mostly solvent with some trace matter through a Buchner funnel. I'll have to come up with something to put this in and mount it to.

Why did you pick this product vs others?:I thought it would preform better. Not enough vacuum

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.

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.

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.

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.

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

Was to small, needed more vacuum for my wiper motor
