The Bathmate Hydromax 5 is a water-based hydro pump that uses the pressure of warm water to support blood flow and fuller erections, all without a single battery or button. Made in the United Kingdom from polycarbonate, medical silicone and phthalate-free TPE, it is built to a standard that matters when something goes against your skin every day. The transparent cylinder is not just a design choice: it lets you watch what is happening in real time, so you stay in control of every session.
The Details
Hydro-pressure system: water creates a consistent, even vacuum that air pumps cannot replicate, making the suction feel smooth rather than sharp.
Total pump length of 26.5 cm, with a 5 cm internal diameter, fits an erect penis up to 14.5 cm comfortably and securely.
Medical silicone and TPE comfort pad forms a soft seal at the base, keeping the pressure steady without digging into skin.
Compatible with water-based lubricants, which protect the TPE seal and make the fit more comfortable from the first use.
Who It's For
The Hydromax 5 is the right starting point if you are new to hydro pumping or if your erect size sits in the compact range and you want a pump that fits precisely rather than loosely. A pump that is too large will not hold pressure effectively, so sizing down is never a compromise. It is equally practical for anyone who travels and wants something discreet and easy to pack, given the relatively modest dimensions.
Usage and Care
Use it in the bath or shower with warm water for three to five minutes per session. Rinse the cylinder and silicone pad with warm water and mild soap after each use. Because the sealing pad contains TPE, stick to water-based lubricants only: oil or silicone formulas will degrade the material over time.
Bathmate has been producing hydro pumps since the early 2000s and this model ships in discreet packaging with no indication of contents. If you have any questions before or after your purchase, support is available seven days a week in both English and Greek.
