Pump Addicted Rx11 automatic erection penis pump, ABS and silicone

The RX11 pump works on a simple but effective principle: creating a controlled vacuum that concentrates blood flow in the penis, allowing for a firm, long-lasting erection without chemicals or injections. I consider it an excellent option for anyone looking for a reliable and discreet mechanical solution.

Automatic vacuum system and maintained erection

The system works in three steps. First, you insert your penis into the transparent cylinder. Then, you press the button to activate the automatic vacuum—the flexible nozzle creates an airtight seal against your skin. Finally, the pressure rises gradually, forcing the penis to expand in length and girth. The transparent cylinder lets you see the effect in real time. Once the erection is achieved, you press the button again to release the pressure, then use the included cock ring at the base to maintain the erection for as long as you wish.

Material, dimensions, and watertightness

The RX11 pump combines ABS and silicone—ABS provides rigidity for the cylinder and vacuum mechanism, while the silicone nozzle conforms perfectly to your shape for a watertight seal. Weight: 380 g. Dimensions: 29 cm total length, 20.5 cm insertable length, 7 cm inner diameter. Fully waterproof, it can be rinsed under water after each use. For a thorough cleaning, I like to use a dedicated sex toy cleaner—it extends the silicone’s lifespan.

Practical use and compatibility

Before first use, make sure the cylinder and nozzle are completely dry. Apply a little water-based lubricant to the edge of the nozzle to improve the airtight seal—it’s a small detail that makes all the difference. The pump works without batteries or a rechargeable battery (manual button system), so there’s no electronics to recharge. Compatible with standard cock rings to prolong the erection after pumping. Between us, many of my female customers tell me that their partners appreciate this non-invasive approach, especially compared with chemical alternatives.

Who it’s for—and who it isn’t

Ideal for: men seeking a firmer, longer-lasting erection, those looking for an alternative to medication, couples wanting to enhance performance without medical intervention, and users of all experience levels (beginners and experienced users). The system is intuitive and safe when you follow the recommended pumping time.

Consider another option if: you have serious circulatory problems (consult a doctor first), you’re looking for a programmable electronic solution, or you prefer something more compact. For a gentler first approach, you can consult our beginner’s sex toy guide, which also covers penis accessories.

Girlfriend tip— Never force the vacuum: increase the pressure gradually. If you feel discomfort, release it immediately. Pleasure comes from gradual progression, not brute intensity.
