Bathmate Hydromax7 - hydro pump (clear)

The Bathmate Hydromax 7 is the world’s leading water-based penis pump - with 35% more suction power, a 360° rotatable bellows pump system and a Super Comfort Sleeve comfort ring compared to the original Hydro series.

Why is the Bathmate Hydromax 7 hydropump good?

The Hydromax 7 is Bathmate’s best-selling model - for most users of average size (erect penis length between 12.5-17.5 cm) it is the perfect choice. Compared to the original Hydro series it provides 35% stronger suction power thanks to the new bellows pump system and the new valve, delivering faster, more intense results. With the “Just Add Water” principle you only need to fill it with warm water, and the natural power of the water creates an even, tissue‑friendly pressure - unlike the uneven and often painful vacuum of traditional air pumps. With regular use several times a week you can achieve up to 6 cm increase in length and 30-40% increase in girth, though even after 15 minutes a visible temporary change can be seen. It is designed for erect penis lengths between 12.5-17.5 cm, up to a maximum diameter of 5.3 cm. It is recommended for anyone looking for the most popular, most well‑balanced mid‑range model in the Bathmate range.

Instructions for use

The Bathmate water‑based (hydro) penis pump can be used in the bath or in the shower. For safe use and good results it is worth following the manufacturer’s official 7‑step routine.

Correct use of the Bathmate step by step:

• 1. Warm‑up: use it in the bath or shower and gently massage the area so that the skin relaxes.
• 2. Filling the pump: close the valve, remove the comfort insert (optional), fill with warm (not hot!) water, then replace the insert.
• 3. Positioning: place the flaccid penis into the pump so that the testicles remain outside the seal. Press the pump firmly against the body to achieve a good seal, then, tilting it slightly upwards, open the valve (the hand pump bulb can be attached optionally).
• 4. Creating the vacuum: pull the pump towards your body to create a vacuum, then pump to a comfortably maximum pressure (by squeezing the hand pump bulb you can further increase the suction effect).
• 5. Waiting for the effect: keep it on for a maximum of 3 minutes, adding a little extra pressure if needed. Then release the vacuum by pressing down the transparent valve cap and remove the pump.
• 6. Massage: with an “OK” grip gently slide your hand from the base of the penis to the glans for about 2 minutes to relax it.
• 7. Repetition: repeat steps 2-6 up to a further two times. The full routine should not last longer than 15-20 minutes, with use on a maximum of 5 days per week (e.g. 2 days use, rest day, 3 days, rest day).

Common mistakes to avoid:

• Rushing: always warm up for a few minutes before the session.
• Over‑pumping: higher pressure does not mean better results - always stay at a comfortable level to avoid injury.
• Overdoing it: stick to the recommended 15-20 minutes; using it for too long can cause temporary swelling or reduced sensitivity.

Good to know: the pump also works without water, with air (e.g. in the shower or bathroom), but warm water helps relax the tissues and improves the seal. It is safe for beginners as well - start with low pressure and short sessions.

Note the following:

• Gradual increase - start with lower pressure and gradually increase the vacuum for comfortable and safe use.
• Use only water‑based lubricant if needed - oil‑ and silicone‑based lubricants can damage the material of the pump.
• Avoid over‑pumping - a continuous session longer than 15 minutes can cause swelling and damage to blood vessel walls.
• Always use it with shaved or closely trimmed pubic hair so the comfort ring can form an airtight seal against the body.
• Before and after use wash it with lukewarm water and mild soap, and dry thoroughly.
• Store in a cool, dry place, protected from direct sunlight.
• If you feel any pain, numbness or discolouration, stop using it.
