  • Increase your penis size by up to 25%
  • Train your erections to last longer

They have been developed for temporary penis enlargement – even with regular use, the results are not permanent. For permanent enlargement we carry a large selection of special products.

Bathmate HydroMax9 use water pressure unlike conventional penis pumps. Thanks to this innovative technology, men can perceive visible growth after only a short period of time

The Bathmate HydroMax9 is suitable for men who have a maximum of 19 cm big penis in the erected state.

How to Use the HydroMax for Maximum Results

  1. Fill your bathtub with water (also possible under the shower)
  2. Once you are sitting in the tub, hold the Bathmate HydroMax9 under the water so that it can completely fill up.
  3. Still under water, put him on your penis.
  4. Now press the pump against your stomach until a vacuum is created. You should be able to feel the pressure increase. Do not worry, excess water is drained regularly through the pressure valve on top of the Bathmate HydroMax9.
  5. Continue to increase the pressure until no more water seeps out of the pressure valve.
  6. If you cannot continue pumping, take a short break.
  7. If it does not work after the break, it means that you have already created the optimal vacuum.
  8. Repeat the exercise for about 4-5 minutes. Each time your penis enlarges, the water is released from the pressure valve.
  9. Again, as soon as no further pumping is possible, you have reached the optimum vacuum.
  10. If the pressure is too high for you, just press the pressure relief valve at the end of the Bathmate HydroMax 9 and the pressure will automatically decrease.
  11. After about 15 minutes, release the pressure and remove the pump from the penis. The training is over.
  12. The Bathmate HydroMax9 should be used only once a day for 15 minutes and only a maximum of 3 times a week for the best results.

Amazing Features

The Bathmate HydroMax9 has the latest technology to enlarge your penis with water technology. It generates 35% more suction power than Bathmate Hercules thanks to its unique, newly designed Bellows pumping system that gives you better and faster magnification.

The Bellows system in the Bathmate HydroMax9, features a new soft seal, fully supportive comfort ring to give you reduced pressure and increased comfort around the root of the penis and testicular region. As an added bonus, it can also be removed for easy cleaning.

New super flow stop valve system that allows you to handle it with a hand in the shower, making it easier to use and place the hydro pump.

How to clean your Bathmate HydroMax9

  1. After use it is very easy to clean the Bathmate HydroMax9. Place both the comfort insert and the penis pump in some soapy water and wash thoroughly.
  2. Rinse everything with clear water and then let the penis pump dry in the air.
  3. Store in a dry place away from direct sunlight when the penis pump is not in use.

If you want to clean the valve, it requires a little more intuition – but it is not hard.

  1. Find one of the two openings on the valve head.
  2. Insert a flat screwdriver into the opening and carefully lift the hat up – about 1 cm – by turning the screwdriver. Do not turn too hard, as you risk damaging the valve. Alternatively, you can gradually raise it slightly until the valve itself pops out.
  3. Remove the valve cap, pull on the black contact and lift out the inside of the valve.
  4. The valve is now removed and you can wash every part with warm soapy water and then rinse with clear water.

When all parts have been washed and dried, you must reassemble the valve.

  1. Place the small contact inside the valve with the soft, transparent packing down. Make sure that the inside of the valve sits correctly with the black contact perpendicular to the valve body. The contact is a square and the opening must be down in a rectangle. Also, make sure the contact is seated so that it can be moved to the right and to the left, otherwise the valve will not work properly.
  2. Place the valve cap back on the valve housing and press it down with a firm pressure, palm down against the spring until you hear it click.

Check that the contact can move left and right and that it clicks when it closes.

Bigger Size, More Feeling, More Enjoyment

Not only do this penis pumps improve the size, volume and duration of your erections, they also provide the most sensitive areas of your penis with more blood, making them even more receptive to the intense stimulation of solo masturbation or lovemaking. With a penis pump you will be able to enjoy intense, unforgettable orgasms.

Penis pumps are popular because of their efficiency and functionality. Just apologize for lovemaking, maybe two minutes from your partner, and pump your limb to the desired size. Your partner will not hear from your helper – and certainly value their enhanced performance.

By the way, the feeling you will feel when using the pump is not to be despised – sucking out the air is a tingling sensation you do not even need to touch your penis.

Not only you, but also your partner will benefit from your penis pump. The magnifying effect of the pump lasts for a few hours, so you will have plenty of time to spoil your partner with your unusually large and powerful best piece!

My Final Thoughts About it

I really do think that the Bathmate HydroMax series in general is the best price to performance of any water-based penis pumps.

I know it’s not the cheapest pump out there but you’re getting premium quality and a really strong pump that has enough power for most users. If you aren’t satisfied with the second best in terms of power then head over to my HydroXtreme review and see what another $100 buys you.

  1. Hi what would be the best pump for a seventy two year male with diabetes. Shrinkage has set in and not much length left.

    1. Hi
      I would go with the HydroMax 5 or 7-inch models depending on your penis size before the shrinkage. It’s very likely that you’ll get it all back if you use it regularly.
      You can see the different models in that range at at

      You don’t really need all the power the Xtreme models have so I would safe my money and the the HydroMax model.

      Best regards,
