Bathmate Hydro7 Hercules

One pump, warm water, and a whole new way to explore your performance.

The Bathmate Hydro7 Pump (formerly known as the Hercules) is a water-powered penis pump designed for men who want a more natural and comfortable pumping experience. Created for use in the bath or shower, it uses hydrotherapy pressure to deliver smooth, even suction that supports firmness, improved blood flow, and enhanced sexual confidence.

Built from medical-grade polycarbonate, skin-safe rubber, and stainless steel components, the Hydro7 is made for durability and repeated use. Its solid yet ergonomic design ensures comfort during each session, while the transparent cylinder allows you to monitor progress with built-in measurement markings.

This model is specifically sized for men with an erect length range of 5 to 7 inches, ensuring a secure and effective fit during use. The water-based system replaces air with warm water, creating a more natural expansion environment that many users find more comfortable and easier to control.

The Hydro7 works through a hydraulic bellows mechanism, expelling water while maintaining a sealed vacuum to generate steady, evenly distributed pressure. Once your session is complete, the quick-release valve allows for fast and safe pressure release without hassle.

Designed for convenience, it fits easily into a shower or bath routine, making it simple to incorporate into regular use. Whether you’re new to pumping or upgrading from a basic device, it offers a controlled, consistent experience when used correctly.

For best results, begin with shorter sessions and gradually increase duration over time, always using warm water to maximise comfort and effectiveness. Consistency is key, and a steady routine helps achieve the best outcomes.

So, how far are you ready to take your routine tonight?
