Hydromax 9 Penis Pump. 35% than the original Bathmate series, these are the best-selling Hydropumps on the market. The Hydromax Series (formerly Hydromax X-series) is the next stage of Hydro Pump evolution. Developing the innovative Bathmate, the new bellows pump and valve give 35% more power than the original Hydro7 with more safety and comfort. New bellows, by introducing new materials into the mix we have been able to create a unique bellows system that is not only stronger and more durable but also gives more flexibility, allowing you to create greater suction with less effort. The internal bellows size has also been increased and the number of convoluted reduced giving you a more comfortable experience. The addition of our new super soft comfort pads have been a revelation in providing a tighter and more comfortable seal against the body, this means less pumping and less loss of suction. The soft-touch outer edge feels great against the body and the rigid inner tube provides a strong and sturdy shield around your penis from the inside of the bellows. Comfort pads are completely removable for easy cleaning and general hygiene. All Bathmate Hydropump products are manufactured from specially selected phthalate free, skin safe and medical grade materials, and each range has undergone a custom designed dermatological testing study undertaken by a world renowned specialist Clinic. Aspen Clinical Research have conclusively passed our Hydropumps as Clinically proven to be safe for use on the genital area. You can be assured that Bathmate Hydropumps are safe to use.
