Basically, a Bathmate Pump is a cylinder placed above the penis, after which air is pumped out of the pump, creating a “void” in the cylinder and around the penis. Pressure from this void helps draw blood to the penis, creating an erection. (In some cases, warm water is used to flood the cylinder initially. Water is then pumped out with air. This is called a water penis pump or a hydro pump.)

Penis pumps are often recommended for men with erectile problems, because they can help them get an erection. Many men, however, use a penis pump to not only get an erection but to get an erection that is larger than usual, which can occur with the use of a pump.

What kind of technology has been used in the pump?

Bathmate series offers you something you will not find anyplace else. It is made with a patented hydro system which uses the power of water to create a vacuum and draw blood to the penis. Though all devices use vacuum feature, every other device uses the force of air for it. On the other hand, Hydromax is completely powered by the water, which makes it much more convenient than the classic designs around in the market. Plus, it is more powerful than other penis enlarger methods too. http://forums.naca.com/?bbp_user=45743

How can it help enlarge penis size?

When water is ejected out of the device, it creates a temporary vacuum force which pulls more blood to penile chambers. This increased blood flow helps men in more than one way. Firstly, if you are suffering from weak erection, this force will improve strength in both the short and long-term. Plus it also helps decrease penile sensitivity to support premature ejaculation treatment.
Finally, over the period of time this blood circulation challenges vessels limits stretching them out and aiding in the production of new cells. Bathmate Hydromax pump is basically designed to offer enlargement benefits only.
