Bathmate Hydromax 9 in clear is a manual, water-filled vacuum pump that Bathmate sizes for users measuring 7 to 9 inches when erect. Its bellows expel water and create a partial vacuum when the chamber is sealed against the body. The maker directs Hydromax products to be used in a warm bath or shower and limits a complete session to 15 minutes.

Choose by fit, not by maximum size
The 7-to-9-inch figure is the maker’s erect-length range. It is not a chamber-width measurement, a target size, or a guarantee that the base will seal comfortably. Measure erect length and girth, compare both with the current Bathmate sizing guidance, and make sure the opening can sit against the body without trapping the testicles. If the chamber or opening does not fit comfortably, do not try to compensate with extra pressure.
The current official Hydromax family page describes a rigid polycarbonate vessel, bellows, a comfort pad, and a latch-style valve. Product design and included parts can change, so inspect the unit you receive and let its enclosed instructions control where they differ from this page.
Use the included instructions
Read the enclosed Hydromax guide before first use. Bathmate directs users to begin with a flaccid penis, fill the pump with warm water, keep the testicles clear of the sealing area, and apply only the minimum vacuum needed. The valve must remain accessible so pressure can be released promptly.
The current guide recommends removing the device every 2 to 3 minutes, allowing the penis to retract, and massaging it in the flaccid state for 2 minutes before reapplying. It permits no more than three cycles and no more than 15 minutes in any 24-hour period. Follow the instructions supplied with your unit if they differ.
Important vacuum-pump limits
- Use only while awake, unimpaired, and able to monitor pressure and sensation continuously.
- Do not use if you cannot operate the pressure-release mechanism promptly or have reduced pain sensation in the penis.
- The maker says not to use the device with sickle cell disease, a history of prolonged erections, a bleeding disorder, or while taking blood-thinning medication. Consult a qualified clinician before use if you have erectile-dysfunction symptoms or any other condition listed in the guide.
- Excess pressure or vigorous pumping can cause bruising or injury. Release the vacuum and remove the pump immediately for pain, marked discomfort, numbness, unusual color change, coldness, swelling, or bleeding.
- Do not fall asleep with the device in place and do not use it while impaired by alcohol or drugs.
- The current guide limits the Hydropump to one user and advises against lubricant because the device is intended for water use.
This page does not promise permanent enlargement, treat erectile dysfunction, replace medical care, or guarantee a particular result. Vacuum use can aggravate some pre-existing conditions, and persistent symptoms or an erection that does not subside require prompt medical advice.
Release, cleaning, and storage
Before beginning, identify and test the release control without a body seal. To remove the pump, press the valve cap inward to release the vacuum and slide the device off only after pressure has released. Never pull against an active vacuum.
Before first use and after each session, wash the Hydropump with warm, clean soapy water and rinse thoroughly as directed by Bathmate. Let it dry completely, then store it dry and away from direct sunlight. Inspect the chamber, gaiter, bellows, valve, seal, and comfort insert before each use; do not use damaged, cracked, loose, blocked, or deteriorated parts.
