Vacuum Pumping 101

Thanks 114life. You are a kind man

Can someone explain how to pump with heat?

I have an LA pump that I haven’t tried yet and wanting to give it a try

Wrap a heat pad around the cylinder.

Can anyone recommend an electric air pump larger than 20cm in Europe, please?
All I’m finding is 20cm long or less.

Safe gains you all.

There are two kinds of electric pumps: ones with the pump forming a cap on the end of the tube, and ones with the pump connected by a hose.

If you get one of the hose type, you can use whatever tube fits you best.

I appreciate it Andy.

What I’m after is an electric pump that maintains the same pressure along the session.
Is that something that exists?
I’m sorry if I’m not understanding, I’m a hanger starting with air pumping.

A small space heater as well

I bought a couple that were *supposed* to do that, but they both ran up to 13”Hg and stayed there, no matter what I tried to set the vacuum to. I finally bought an aquarium pump and used a bleeder valve. It will pull about 4.5”Hg with the valve shut; I usually crack it open enough to drop the vacuum to 3” or 3.5”, which I’m most comfortable with.

Use the search box and put “aquarium” in, and the big pump conversion thread should show up.

Thanks as always Andy (also for sharing the nude pics in other threads)

I’m looking into that now, interesting.

Someone with symmetry growth problem under the shaft. The lower part of the left side has grown more than the right side. Is this due to the heat pad?

That is usually a sign of too much vacuum or time in the tube. What is your pumping routine?

I used to do it 5 days a week, now I try to do it every 3 days. The duration is usually 2 hours in total. 1 hour 5-7 hg. 1 hour lower 3-5 hg. I’m trying to do core pumping management. The thing I mentioned is new. Is there a possibility to fix the missing aspect?

What is it? Core pumping management…pls explain

Method of someone filling a 3.5 inch tube on another forum.

First pack the tube sample 5 hg. Then, either in the tube you are in or in a smaller tube in a lower vacuum, the sample stays for 3-4 hg for the same time or less.

Give me the link please so tha I can check….pm me. Thanks
