Fridge Compressor As A Vacuum Pump

Hi.
Have you guys considered using a fridge compressor as a vacuum source for pumping?
These pumps can reach stronger vacuumes than what a normie dick can handle at 20Hg+.

Simple example.

They should probably be purged thoroughly with nontoxic mineral oil before use though.

The PE4F style of pumping uses an industrial pump of various power that will reach ~28Hg in less than 3 seconds.

Short answer it has been done, is being done and I have a log in my signature that has a lot of comments regarding the theory behind it and how a pumping apparatus may be constructed. PE4F High Pressure Pumping: thoughtfulgold

Vacuum yes, but with a refrigerator style pump? I’m talking about general pumping use and not necessarily high intensity pumping.
These can be scavenged for so cheap.

Given the levels of vacuum, spending $90 on a pump that you can trust versus scavenging and rigging up a refrigerator pump may not be economical compared to the control and safety you lose. As you would need to purify the system, install a hard power switch then inspect the system for leakages and account for the age of said pump whenever using it.

I mean, I’m not sure there is a difference in the vacuum generated either. As the style of pump is similar as far as I know and you likely would end up with extreme vacuum levels in a few seconds the same way the industrial pump I use also works.

I honestly do not know and can’t be sure how well it would work. *shrugs* I would do extensive testing if scavenging and making a usable system with the refrigerator pump is the goal here.

I don’t know if a fridge pump can pump air without additional lubrication. You’d also have to design a way to connect it to a penis cylinder.

That was a surprisingly negative assessment :O

Refrigeration compressors are designed to compress refrigerant and oil. When the return gas temperature exceeds 60 to 65 degrees Fahrenheit, the motor windings begin to overheat. Also the way you are utilizing it when air is mixed with the oil, the oil becomes contaminated with moisture. The moisture reacts with the oil to form acid, which will eat at the enamel on the motor windings, eventually causing a short circuit to ground. So I would not expect a long amount of runtime with this setup.

I used fridge compressor many years ago. Used for few years. I agree with PE4Fun that it should be 1 -2 session per week. Because of the great stress. Session 15-30 minute (20- is good). The practice is the follow. 2 sec - pumping from zero to ~30Hg as you can. (You should listen your body. Extreme - prohibited). After these 2 sec - quick release pressure to the zero. When air is releasing from the tube the pipe must be closed and the pressure in the pipe and in the compressor is increasing. After 2 sec - switch this pipe to the tube for the second 2 sec session 0-30Hg. I did mechanical construction for that. My results was perfect in that time. Good lack. (sorry for my English).

Yes and I recall a discussion here a long time ago included using a fridge compressor. So you might try the search feature here. The advantage of these compressors is they are usually very quiet. Since the vacuum side is used there is no need to worry about "contamination" etc. but the positive pressure side might drip a bit of oil. The disadvantages (as I see them) are: these things are heavy; use high voltage (compared to 12VDC); the capacity is unnecessary for our purposes; and even if free they will require other parts to make functional.

ANY Suck and Release Pumps Out There Besides CTC?

Consider 12VDC or 5VDC (USB) as your power source. Once you start there you will discover a whole world of cheap stuff to experiment with such as:
air pumps (<$20)
timers (<$10)
electric valves (<$10)
digital vacuum switches (<$50)
battery packs (<$20)

Ebay, AliExpress, Amazon and other online sellers have this type of stuff.

Let us know what you come up with.

Thanks for the detailed replies folks!
At the moment I have no direct plans for making a pump. Simply spittballing.

I do however have a design for a fully automated jelq machine that I would like to show you guys, but it will have to wait until I reach the legendary 200 posts threshold to publish it.

Or publish it now, then message a mod to as them to move the thread to the target forum…*hint hint*

Now after proof reading my post, I noticed that I forgot to add the words “concept” & “drawing” to it.

But if you insist, where would be the best place to post it?

Probably just the general “Penis Enlargement forum. It isn’t a completed product you’re selling and we don’t have a jelq device forum.
