According to the user guide that accompanies each one it's 0.4 bar in water.
In inches of mercury that ain't much.

.4 bar is about 12 HGs right
 
X-40 stats!

Maximum Force To Compress Gaiter -10kg
Maximum Vacuum Created (Air) - 5" mercury
Maximum Vacuum Created (Water) -12" mercury
 
More vac with water eh? Hmm. Weird because if I pump with my plane jane tube from LA Pump (a quality tube btw) with water, I can get the SAME HG regardless of water being in the tube. It does however take more effort (more pumps on the hand pump) to get the same HG. That's measured on an actual gauge too by the way...not just guessing How does water magically alter the vac inside the Bathmate? If anything, a guy should NOT be able to generate as much HG inside a Bathmate assuming he's using water as the Bathmate is designed to be used. Remember, the Bathmate has no hand pump and no way to visually measure how much vac is actually being generated. I'm asking out of curiosity not criticism. Granted I have a rudimentary at best understanding of hydraulics and physics in general, but please tell me how having less volume inside of a pump tube (penis and air) would create less vacuum than having more volume inside a pump tube (penis and water). That just seems very counter-intuitive.

Again, I'm not criticizing this product, I know it's great and works. I also understand marketing though. I realize this product is made as a product "for the masses" who do not want to commit to pumping in the traditional sense. Guys who want a "simpler" way to pump. Also, I'm sure the fact that the Bathmate is meant to be used WITH water, which makes it safer in general (lower vacuum...less chance of injury such as blistering) is appealing to the manufacturer from a legal standpoint.

Let's make sure we have our facts straight gents ;)

Those are the stats provided by Bathmate in the users guide: 0.4 bar in water, 0.17 bar in air. Air is compressible and expansible, water is not, it doesn't seem to make sense that it would effect vacuum and pressure characteristics the way it does, but in actual practice that's how it works.

I remember testing relief valves with a dry nitrogen set and they all worked IAW spec; then an old pro told me to put 'em on the flow bench using the same oil they were designed for= all outta spec. And that's 'cuz two different fluids, liquids and air, have different volume and pressure properties.

Kinda counterintuitive, but that's how they are.
 
actually the pressure is not what is important here but how the air and water affect the skin!

Water moistens while air dries the skin.

I had the best sessions filling the Bathmate to the top while having full erection!

That's sort of like saying it doesn't matter if you get expansion or a stretch when you do slow squash jelqs or stretch.

???

Are we talking Bathmate or manual work?

As far as i know most of the people get results from using it with water, trying to just use air gets you no pressure...
 
I find that hydropumping seems to focus the pressure more uniformly (Even) across the penis then conventional pumps which because of the space around the penis (Which is air) it seems to want to suck more, sort of gripping more at the penis if that makes sense. The Bathmate-way with the water is like a glove fitting your hand and its a perfect fit, as water adjusts to anyone. The vacuum then from my way of thinking evenly distributes this pressure over the penis and focuses it more accurately and explains why guys such as myself get the best sessions with this then they did with more powerful conventional dry pumps.

I hope it's not that high. Imagine the injury potential.

Yeah, that's why I am asking. From what I've read, the "understood" safe HG for pumping is 5hgs or less, definitely 7 max. I've read that plenty of people go above that all the time and have no problems, but I am a newbie. Id say most all of us Bathmate pumpers go over that all the time if we pump to max pressure and max pressure being 11.8hg or.4bar. So that was why I was asking. Just bought the Bathmate in Feb. so wanted to make sure I was not creating creating any damage from pushing it too hard too fast.
 
Okay, I gotta admit that when it comes to terminology I'm anal retentive about it.
Just so everybody's on the same page, what we're talkin' about producing inside the Bathmate is a partial vacuum; not pressure.
Measured in in/hg (inches of mercury) or bar (the metric equivalent) these are measurements of less than atmospheric pressure in a given volume, and are just about the most commonly used values.

So if you're gonna use mercury; please specify inches, because millimeters are also used (as in blood pressure) and, being the anal guy I am I'd like to keep newer guys who might not be familiar with this stuff at all from getting confused with inconsistent terminology.
 
Ya I hear you max! We are creating negative pressure not pressure. I also like the term partial vacuum. I don't know much any thing about the amount of partial vacuum but with a Bathmate its built in and you can't really over pump like with an old type air pump. Really to me this discussion in irrelevant but I guess some people just want to know. Me I don't don't care. Its a fixed amount and it works. I can feel the pressure and if it was toomuch people would have problems along time before me.
