The Bathmate range of Hydropumps operate using hydraulic pressure around the penis. Because the surface area of the penis is larger around the girth than it is the length, it is the girth that users will experience an increase in first, often resulting in them touching the sides of the pump meaning that the hydraulic pressure will not be able to expand the girth of the penis further. In addition, the hydraulic pressure around the penis reduces as the space increases, which is why in order to obtain maximum hydraulic performance, the correct size pump must be used.
