Why use a hydropump as opposed to an air pump?

This is a question we are asked a lot, and to answer it, we need to take a brief look at the science behind penis pumps. Penis pumps have been around for many years now, not only being used by men to both increase the size of their penis and the quality of their erections, but they have also been used for many years in the medical sector for helping men with erectile dysfunction. Prior to the invention of the Bathmate Hydropump, all penis pumps operated using air the Bathmate Hydropump was the first to use water inside the vacuum tube and is the acknowledged world leader in hydropump technology.

AIR

Under pressure, air is inconsistent and unpredictable. When air is removed from a vessel, an uneven vacuum is created due to the air being removed too quickly, which can lead to bruising, bending, and bulging of the penis.

WATER

Water is consistent under pressure and can be drawn out of the vessel much slower than air. When water is expelled from the vessel, an even vacuum is created around the entire length and girth of the penis. This creates an even, solid cushion around the penis and allows for uniform expansion without any of the nasty side-effects associated with air pumps.
