A hydropump is a type of penis pump which uses water, rather than air, to create suction. Like air-based pumps, Hydropumps help men achieve larger, stronger, and longer-lasting erections. They can effectively treat erectile dysfunction and enhance the sex lives of all users, whether they suffer from erectile disorders or not.
Hydropumps are a relatively new invention, first hitting the market in 2014. Penomet and Bathmate are among the highest selling hydropump brands.
