The Hydromax 9 is Bathmate’s largest water-based penis pump, designed for use in the bath or shower. At 35 cm total length with 23 cm insertable depth, this pump uses hydraulic pressure rather than air to create consistent suction around the penis.
How the Bellows System Works
Fill the vacuum chamber with water, insert yourself, then compress the bellows to create suction. The soft removable comfort ring sits against the base to reduce pressure around the testicles while maintaining seal integrity. A full 360-degree swivel valve lets you adjust the angle mid-session without breaking suction — useful when you’re working around taps or positioning yourself at an incline.
Single-Hand Operation in the Shower
The Super Flow Latch Valve allows you to fill and position the pump with one hand. Upper and lower texturing on the plastic chamber gives grip when wet. A metric and imperial scale inside the tube tracks your measurements over time.
Built for Durability
Manufactured in the UK and tested to 100,000 usage cycles — equivalent to three years of regular use. All plastic components are moulded to precise tolerances. The removable comfort ring detaches for cleaning.
