Water Instead Of Air
A standard pump pulls air out of a cylinder. A hydropump fills with water first, and the water is what carries the pressure – which spreads it evenly around the whole shaft rather than concentrating it wherever the seal happens to be tightest. In practice that means a more comfortable session and better contact, and it is the reason these are used in the bath or the shower rather than on the sofa. Bathmate rates the Hydromax at 35% more power than their original Hydro.
Getting The Size Right
This is the part most people get wrong, so read it before you buy. The number in the name is a fit range, not a goal: the Hydromax 7 is built for users between 5″ and 7″ in erect length, with girth up to 6.5″. The cylinder measures 10″ internally, and that headroom is normal – a pump needs room above you to draw. Buying a larger number than you measure does not get you a better result; it gets you a bad seal. The range runs 3, 5, 6, 7, 7 Wide Boy, 8 and 9, and the Wide Boy exists specifically for girth that does not fit the standard bore. Measure honestly and buy the one that matches.
What It Does, Said Plainly
Pumping draws blood into the penis, which produces a firmer, fuller erection and a distinct full, heavy sensation a lot of people pump for on its own. That is what this does. There is no fact-based evidence that a penis pump will produce permanent enlargement of the penis. Any enlargement gained by pumping is temporary. These products are sold for recreational use and are not intended to diagnose, treat, or cure any medical condition.
How To Use It
Use it in a warm bath or the shower. Fill the cylinder with water, seat it, and pump in gradual steps rather than going hard for maximum straight away. Bathmate’s own guidance is 15-minute sessions, up to five times a week – and more is not better here. Hit the pressure-release valve the moment you feel pain, numbness, tingling, or see any change in skin colour. If you want the fundamentals and the safety rules in one place, our penis pumps guide covers manual, gauge, automatic and water pumps side by side.
Materials And Care
Bathmate builds the Hydropump range from phthalate-free, skin-safe materials, and says the range passed a dermatological safety study carried out by an independent clinic. Rinse the cylinder with warm water after every session, clean it with a toy cleaner, and let it air-dry fully before it goes back in the cupboard – a pump that lives in a bathroom needs to actually dry between uses.
Fifteen Minutes In The Shower
The water is hot and the bathroom door is shut and nobody needs you for a quarter of an hour. You seat the cylinder, feel the water shift, and start working the pressure up in slow increments – a little, then wait, then a little more. There is a point somewhere in the middle where the sensation stops being something you are doing and starts being something happening to you: heavy, full, unmistakably there. Fifteen minutes later you step out feeling like you got away with something. Add it to your cart and take the shower back.
Discreet Shipping And Billing
We have been the discreet ones in this business since 1996. Plain unmarked box, neutral return address, discreet billing, free shipping over $75. We also tell you what a product is and is not – which for pumps means being straight about what pumping does, and being straight about which Bathmate model is actually in the box.
Which Hydromax size do I need?
The Hydromax 7 fits users between 5″ and 7″ in erect length with girth up to 6.5″. Measure first and match the number to yourself – a cylinder that is too large gives you a poor seal, not a better session. The range runs 3, 5, 6, 7, 7 Wide Boy, 8 and 9.
Do penis pumps permanently increase size?
There is no fact-based evidence that a penis pump will produce permanent enlargement of the penis. Any enlargement gained by pumping is temporary. We make no claims of permanent enlargement. These products are sold for recreational use and are not intended to diagnose, treat, or cure any medical condition.
Does it come with a handball or an accessory kit?
No. The Hydromax 7 is the pump itself. The detachable handball and the expanded accessory kit belong to Bathmate’s HydroXtreme range, which is a separate line. If those are what you want, you want a HydroXtreme model rather than a Hydromax.
How often should I use it?
Bathmate recommends sessions of about 15 minutes, up to five times a week. Build the pressure gradually and use the release valve immediately if you feel pain, numbness, tingling, or notice any change in skin colour.
How do I clean it?
Rinse the cylinder with warm water after each session, clean it with a toy cleaner, and let it air-dry completely before storing. Do not put it away damp.
