New Electric Vacuum Pump

I have been enjoying hands free pumping using a modified aquarium pump by Tetra. But this pump has limitations. It pumps at a constant pressure and the one I got only delivers 3.5”hg vacuum pressure a there is no in line gauge to monitor the pressure.

I found a new pump on ebay that features a gauge and variable pressure control. Although I usually only pump up to 5”hg max, this pump is capable of 10”hg pressure. The pump sells for $99.99 and the only drawback is that it is louder then the aquarium pump, but it is definitely more powerful which is a big plus.

The pump comes with all of the necessary plumbing to be hooked up and ready to go in about a minute and the vacuum hose is very soft and pliable which turns out to be quite nice. To increase pressure you just screw in the outflow valve set screw.

If you want to take a look:

This is a very cool and old school pe technique. I made one of these over 15 years ago in high school. Didn’t using it much. No privacy when your a kid.

Just discovered a new technique for this pump. If you want to cycle the pressure up and down, all you have to do is hold your finger over the outflow valve to increase pressure and then release to bring the pressure back down to the set pressure.

The cycling up and down is very effective for me.

What do you mean by very effective, surely you haven’t seen gains already?

Oh yes I have. This pump rocks. It is a very effective pump solution.

This is very interesting gprent. What upper and lower pressures are you using, how long do you hold the higher pressure for and what is the overall time of a typical session?

I think this is the same pump that PE depot sells but with a gauge for the same price. Wished I’d seen this before. And Gprent is quite right you can indeed play with the pressure but I don’t dare because I don’t have a gauge and it is very easy to get out of hand. Does anyone know where I can grab just a gauge for cheap?

What sets, vacuum level, time and frequency are you using Gprent?

For now, I start off at 3”hg for 5 minutes, increase to 4”hg for a couple and then set 5”hg for 20 minutes and then 6”hg for 5 to 15 minutes or so. Total time is 30 to 45 minutes.

There is an outflow valve with a T-handle set screw that controls the pressure. The more you turn this set screw in, the less pressure is allowed to escape and therefore the higher the pressure. You can also easily cycle the pressure up and down by just holding and releasing your finger over the end of this valve.

This is not a very sophisticated pump like the very expensive ones on the market, so time and frequency are controlled by you.

What gains have you seen?

I really haven’t had is long enough to say, but I do know my after pump flaccid size is doing much better. This pump just seems to give a more powerful pump effect at the same pressure as a static pump. In other words, 5”hg on this pump feels more powerful then 5”hg on a hand pump. I think this pump gives a slight pulsing action that contributes to this feeling.

Hi gprent, are you staying in the tube for the whole time ?
If you take breaks do you stay in the tube and drop the pressure or exit for a couple of minutes ? thanks

Yes, I stay in the tube the entire time and don’t drop the pressure. Just keep on slowly increasing it. I do move the tube around a lot with my hand to help keep the blood from stagnating.

My pumping schedule is 3 on 1 off, 2 on 1 off. That corresponds to my weight training schedule where I pump iron on my day off pumping my cock or vice versa.

Thanks, I’ve always thought a long session with no breaks might be better for gaining but I’ve not had the nerve to try it yet.
I’ll maybe start building up to it.
