Buy Penis Pumps – hydro, electric and manual models

How does a penis pump work?

The penis is inserted into a cylindrical chamber. By removing air (or water in hydro pumps), a vacuum is created that draws more blood into the erectile tissue. The penis becomes harder and fuller than during a normal erection. Combined with a cock ring, the erection can be maintained for up to 30 minutes after removing the pump. The increased blood flow also makes the penis more sensitive – stimulation feels more intense.

The effect of a penis pump is primarily temporary – the enhanced erection lasts as long as the cock ring keeps blood in the erectile tissue (maximum 30 minutes). According to manufacturer data, regular use can improve tissue blood flow over time. Realistic expectation: immediately visible harder, fuller erections – long-term size gains are possible but not guaranteed.

Pump types

Hydro pumps (Bathmate)

Hydro pumps use water instead of air. The cylinder is filled with warm water, and the pump removes the water to create the vacuum. According to the manufacturer, this generates up to a third more suction than air pumps. The Bathmate Hydromax series is the core: Hydromax 3 Clear (entry size), Hydromax 5 Blue, Hydromax 7 Clear and Hydromax 7 Blue (standard size), Hydromax 9 Red and Hydromax 9 Blue (above average). The number indicates maximum penis length in inches. All Hydromax models feature 360-degree rotation, a soft seal and a metric/imperial measurement scale.

The Bathmate HydroXtreme series (HydroXtreme 9 and HydroXtreme 11) is the premium line with a handball pump for stronger vacuum and a hose system for more precise control. For users who already have experience with hydro pumps and want more suction and finer pressure control.

Automatic pumps

Automatic pumps create the vacuum electrically – no manual pumping needed. The MegaLift Automatic Penis Pump has a soft silicone chamber, a digital display for suction control, IPX7 waterproofing and USB charging (210 minutes charge time, 2 hours battery). Two interchangeable inserts (2 and 2.6 cm diameter).

The TechnoThrust Masturbator Pump combines vacuum with a TPE inlay that doubles as a masturbator – digital display, suction and vibration modes combinable, IPX7 waterproof. The StrokeMate Rotation Pump adds rotation and thrusting: 2 motors, 9 speeds, TPE inlay, IPX7, USB. The Boners automatic Pump Stroker merges penis pump and masturbator in one device with an integrated pressure gauge and removable insert. The Aqua-Pro AI Penis Pump combines water and air vacuum with automatic control.

Manual pumps

The Power Pump series (available in Black, Purple, Blue and Red) is the entry-level option: transparent cylinder with measurement scale, pump ball, soft PVC opening and a safe release valve. Manually operated, full control over suction. THE JACK PUMP is a glans pump that focuses suction on the head of the penis – keeping blood concentrated where it matters most.

Speciality pumps

The Eichel Pump-Sucker focuses on the glans rather than the full shaft – targeted and intense. The Vibro Air Fuck Pump combines vacuum with vibration for dual stimulation. Both are more compact than full-shaft pumps and suited for targeted stimulation of specific areas.

Which pump suits you?

• Beginners: Power Pump (manual, affordable, full control) or Bathmate Hydromax 7 (hydro, gentler due to water).
• Comfort and automation: MegaLift Automatic or TechnoThrust – digital control, no manual pumping.
• Stimulation + pump: StrokeMate Rotation Pump or Boners Pump Stroker – vacuum plus masturbation in one device.
• Maximum: Bathmate HydroXtreme – strongest vacuum, hose system, premium build.

How to use

Lube on the cylinder rim and penis shaft makes insertion easier and improves the seal. For hydro pumps, fill the cylinder with warm water and use in the shower or bath. Build vacuum slowly – do not go straight to maximum. Most models have a measurement scale on the cylinder. After 15 to 20 minutes, release the pump. Have a cock ring ready to maintain the erection after removing the pump. If you experience pain, numbness or discolouration, stop immediately. For beginners, the manual Power Pump is ideal – you feel exactly how much pressure you build and can release instantly via the valve.

Care

Rinse the cylinder with warm water and a drop of washing-up liquid after each use. A cylinder brush (included with many models) helps with thorough cleaning. Dry well. Clean TPE and silicone inserts separately. Avoid harsh cleaning agents. Rinse hydro pumps (Bathmate) immediately after your shower session – limescale from water can cloud the cylinder.

Frequently Asked Questions

Which penis pump for beginners?

The Power Pump (manual, affordable, full control) or the Bathmate Hydromax 7 (hydro, gentler). Both let you control the vacuum yourself and increase gradually.

What is the difference between a hydro pump and an air pump?

A hydro pump like the Bathmate uses water instead of air. The water distributes pressure more evenly and feels gentler. According to the manufacturer, hydro pumps generate up to a third more suction.

How long should I use a penis pump?

15 to 20 minutes per session. No longer. Build vacuum slowly; stop immediately if you feel pain or numbness. A cock ring helps maintain the erection after removing the pump.

Is a penis pump painful?

Not when used correctly. Excessive vacuum or prolonged use can cause bruising or swelling. Follow the instructions and increase gradually.

Which Bathmate size do I need?

The number indicates maximum penis length in inches: Hydromax 3 (up to 3 inches), 5 (up to 5), 7 (up to 7, standard), 9 (up to 9). When in doubt, choose the next size up.
