Penis Pumps

A penis pump temporarily enlarges the penis using negative pressure—for a harder, fuller feeling and, for some men, to help with erection problems. Here you’ll find manual pumps, electric penis pumps, and water pumps from brands like Bathmate. Check out the full selection of all cock & ball toys or go back to all sex toys for men.

What is a penis pump?

A penis pump — also known as a penis pump, vacuum penis pump, erection pump, or penis enlargement pump — is a cylindrical device that temporarily enlarges the penis using negative pressure. The penis is placed inside the cylinder, after which air or water is pumped out. The negative pressure draws blood into the erectile tissue, causing the penis to swell and become harder. Penis pumps, penis pumping, and buying a penis pump are commonly used search terms. Vacuum pump for men, vacuum penis pump, and vacuum penis pump all refer to the same type of product.

What does a penis pump do?

A penis pump provides temporary enlargement of the penis by increasing blood flow through vacuum action. After pumping, the penis is larger, harder, and more sensitive than usual for a short time. The effect lasts 15 to 30 minutes. Penis pumps are used for two reasons: as an erotic aid for a more intense erection and as a therapeutic aid for men who have difficulty getting or maintaining an erection. A penis pump is not a medical device and does not replace medical treatment for serious erectile problems. See also our selection of better erections.

Types of Penis Pumps

Manual Penis Pump

The most common type: a cylinder with a hand pump that you operate by hand. Each squeeze of the pump removes air from the cylinder and increases the vacuum. Easy to use and immediately available without charging time. Penis pump, penis pump, and penis pumps generally refer to this type.

Electric penis pump

A motor-driven variant that pumps automatically. Provides a more consistent vacuum than a manual pump and requires less effort. “Electric penis pump” and “electric masturbator” are terms that are sometimes used interchangeably—an electric penis pump works via vacuum, not via a channel. “Masturbation device” also sometimes refers to this type.

Water pump — Bathmate

Water pumps use water as a medium instead of air. Bathmate is the best-known brand for hydro pumps. Bathmate penis pump and Bathmate Hydro Vibe are specific product names. The water provides more even pressure across the surface of the penis than air, which can be perceived as pleasant. Use in the bath or shower. Water penis enlarger and hydro penis pump refer to this type.

Penis suction device

Penis suction device and penis suction pump are informal names for vacuum pumps. They refer to the same type of product as a penis pump—the suction effect is the defining feature.

How do you use a penis pump safely?

Never pump beyond what feels comfortable. Start at a low vacuum and build up slowly. Never wear the pump for more than 15 to 20 minutes at a time—too long or too much pressure damages the erectile tissue and can lead to scarring. Remove the pump immediately if you experience pain, tingling, or blue discoloration. Use the sealing ring at the base to ensure a good vacuum seal—a poor seal results in ineffective performance. If necessary, trim the pubic hair at the base for a better fit.

Frequently Asked Questions About Penis Pumps

Does a penis pump permanently enlarge the penis?

No. The effect of a penis pump is temporary—the enlargement disappears as soon as blood flow returns to normal, usually within 15 to 30 minutes. There is no scientific evidence that regular use leads to permanent enlargement. Claims of a permanent effect are unsubstantiated.

Is a penis pump safe?

When used correctly—limited duration, moderate pressure—the risk is low. Excessive pressure or prolonged use can lead to bruising, hemorrhages in the erectile tissue, or damage to blood vessels. Always use a pump with a pressure valve system that prevents overpressure. Men with blood clotting issues or who are taking blood thinners should consult a doctor first.

What is the difference between a manual and an electric penis pump?

A manual penis pump offers more control—you control each pumping motion yourself and feel the resistance immediately. An electric penis pump pumps automatically and provides a more consistent vacuum without effort. Beginners are best advised to start with a manual pump before switching to an electric model.

Does a penis pump help with erection problems?

A penis pump can help men with mild erection problems achieve an erection by mechanically drawing blood into the erectile tissue. For serious or persistent erection problems, medical advice is recommended—a general practitioner or urologist can determine the correct cause and treatment. A penis pump is not a substitute for medical treatment.
