Bathmate Hydromax 9 - hydro pump (clear)

The Bathmate Hydromax 9 is the largest Hydromax model of the water-based penis pumps for larger users - with 35% stronger suction power, a 360° rotatable bellows pump system and a Super Comfort Sleeve comfort ring.

Why is the Bathmate Hydromax 9 hydropump good?

The Hydromax 9 is the largest model in the Hydromax range, designed specifically for users who are already on the larger side - for a erect penis length of 17.5-23 cm, up to a maximum diameter of 6 cm. Anyone who has outgrown the Hydromax 7, or naturally falls into this size range, will find the right fit with this model. Compared to the original Hydro series, it provides 35% stronger suction power thanks to the new bellows pump system and new valve. Based on 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 traditional air pumps with their uneven, often painful vacuum. With regular use, size increase can be achieved with greater safety and comfort than with classic pumps. It is recommended for those who are already past the beginner stage or who are naturally in the larger size category, and who are looking for a simple, reliable larger model without the hand pump and accessory kit of the HydroXtreme series.

Instructions for use

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

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 put the insert back.
• 3. Positioning: place the flaccid penis in the pump so that the testicles remain outside the seal. Press the pump firmly against your body for a good seal, tilt it slightly upwards and open the valve (the hand pump bulb can be connected optionally).
• 4. Creating the vacuum: pull the pump towards your body so that a vacuum is created, then pump up to your comfortable maximum pressure (by squeezing the hand pump bulb, the suction effect can be further increased).
• 5. Waiting for the effect: keep it on for a maximum of 3 minutes, adding a little pressure if necessary. 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 allow it to relax.
• 7. Repetition: repeat steps 2-6 up to a further two times. The full routine should not last longer than 15-20 minutes; weekly use a maximum of 5 days (e.g. 2 days use, rest day, 3 days, rest day).

Common mistakes to avoid:

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

Good to know: the pump will also work 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 too - start with low pressure and short sessions.

What to watch out for when using the Bathmate Hydromax 9 hydropump

• Gradual increase - start with lower pressure, gradually increase the vacuum for comfortable and safe use.
• Size matching - this model is made for larger sizes; if your erect penis length is under 17.5 cm, choose the Hydromax 7 for a better fit.
• Use only water‑based lubricant if needed - oil‑ and silicone‑based lubricants can damage the material of the pump.
• Avoid over‑pumping - more than 15 minutes in one continuous session can cause swelling and vascular damage.
• Always use with shaved or closely trimmed pubic hair so that the comfort ring can seal airtight against the body.
• Before and after use, wash with lukewarm water and mild soap and dry thoroughly.
• Store in a cool, dry place, away from direct sunlight.
• If you feel any pain, numbness or discolouration, stop using it.
