The Vaxaid V7 Deluxe penis pump is a versatile combination air and water pumping device. It can be used with other treatments to maximise your chances of getting an erection.



About penis pumps
The Vaxaid V7 Deluxe is a versatile device
VaxAid creates a vacuum around the penis, either using water or air pressure, drawing blood into the penis, resulting in a full erection. Used in water, this produces a natural feeling erection. Because the Vaxaid V7 Deluxe can be used as an air or water pump, you have the option to try out both methods without buying more than 1 device. This means you can find the method that suits you best without paying twice.
The Vaxaid V7 is a hand operated penis pump
While alternative battery powered penis pumps are available, the Vaxaid V7 is hand operated only.
Penis pumps aren't first line treatments
The first line treatment for erectile dysfunction is normally lifestyle changes and PDE5-inhibitor medications like Viagra.
However, you can use penis pumps like the Vaxaid V7 Deluxe alongside other treatments like Viagra or Sildenafil. It is also a non medical option for people who can't or don't want to use medications.
Side effects of penis pumps include:
- coldness, numbness, blue tinge to the skin: these could be due to the constriction band, so you should remove it immediately
- bruising, little red dots or pain: bleeding under the skin of the penis causes this
- discomfort: your ejaculation might be painful or you might feel like some of the semen is partly trapped in your penis
- gangrene: this is a rare but very severe complication, which can happen if the constriction ring is left on the penis for too long so that there isn’t blood flow into the penis
It is not safe to use a penis pump if you:
- take blood thinning medication
- have any conditions that affect blood clotting
- have any penile or urethral conditions such as skin problems or a bend in the penis

They can be highly effective for some men. Penis pumps are devices that are designed to improve the quality of erections. The V7 Deluxe is ideal for well over 90% of men, supporting lengths up to 7 inches.
They can be combined with other erection treatments. If you’re looking for long term improvements to your erections, then a combination of lifestyle changes and pharmacological treatment is recommended. The lifestyle changes include regular exercise, weight loss if you're overweight, trying to quit smoking and drinking less alcohol.
They don’t increase the size of erections in general. An important point to mention is that a lot of men might think that penis pumps can increase the size of their penis. There isn’t any evidence to support this, so that shouldn’t be the reason you want a pump. You should only use a pump if you’re medically advised to. It’s always a good idea to see a doctor if you are suffering from erectile dysfunction, to check for any underlying causes and to see if a penis pump is safe for you to use.

Get professional advice: the best thing to do is get assessed by a doctor. This is particularly important because some pumps are available without a prescription and might not be safe or effective for you. Remember to tell your doctor about any medical conditions you suffer from, and any medications you take.
Check your options: there are quite a few choices to make when you’re trying to decide the best penis pump for you. Even though a lot of men report high satisfaction rates with their pumps, it doesn’t mean that just any pump is the right one for you. Think about your choice beforehand and it can help you get what works best for you.
Automatic versus manual pumping: one of the first decisions is whether you want a battery operated or manual vacuum pump. All pumps generally work when there’s a seal between the skin and the cylinder of your pump. The pumps all create a vacuum around your penis but in different ways. A manual pump might involve you pushing a plunger or squeezing a lever to increase the pressure you need, whereas battery operated pumps work just with a press of a button. When you’re picking, you should also see if the pump has a vacuum limiter, which prevents the pressure from becoming too high and potentially causing injury.
Consider your budget: a benefit of penis pumps is that they’re a one time expense, but some of the battery operated pumps can be quite expensive. Whilst you might be able to get your pump on prescription (you’ll need to check if you’re eligible), most men have to buy their own pump and the price might be up to £500.
Air based based pumps: air pumps create a vacuum so that blood rushes into the penis to get an erection. Even though you can achieve a good erection with these pumps, you might need to continue to pump for a while. You need to be careful though since it’s possible to get tissue damage with the repetitive action.
Water based pumps (also called hydro pumps): these might be simpler to use than air pumps. They claim to distribute pressure more evenly than air, by using warm water, which fills the pump before it’s placed over the penis.
Combination air and water pumps: the Vaxaid V7 Deluxe, offered through ZAVA, is an example of this type of pump.
Find the right size: before requesting your penis pump, make sure the model is the right size for your erect penis. The Vaxaid V7 Deluxe supports an erect penis of up to 7 inches, and is suitable for over 90% of men.
To measure your penis accurately, place a ruler, or a similar measuring device, against the base of your erect penis.

The Vaxaid V7 Deluxe vacuum pump: this is a comfortable and convenient pump, which comes with a manual guide and USB guide to help you every step of the way. It's unique because it can be used both in water and air. Its system forms a safe and comfortable seal on the pelvic seat and it’s well designed so that there’s full and even blood flow along the length of the penis without any risk of your penis bulging/bending (which can happen with a lot of vacuum devices).
Using the Vaxaid V7 Deluxe in water: when used in water, the water around the penis improves the blood flow into the penis. The water also works as a lubricant, providing some cushioning and comfort for you.

Vaxaid has provided a video which shows exactly how to use their product.
Before you use a penis pump: you should always take a look at the product instruction manual or USB guide that comes with it. If your doctor provides you with additional instructions or directions that differ from these, always follow your doctor’s advice.
To use your Vaxaid pump:
- place the pump over the penis. You can use a lubricant to make this more comfortable
- pump the air out of the cylinder so that a vacuum is created. How to do this will depend on the type of pump you have, so refer to your manual for this
- continue to pump out the air until the penis is erect
- when the penis is erect, and by using lubricant, slide a retaining band down onto the base of the penis
- remove the pump after releasing the vacuum, leaving the band in place
Using the constriction band: you can keep the band on for up to half an hour after you take off the pump. During this time, you can have sex as normal, but you need to be careful not to leave the band on for longer since this could cause some tissue damage.
Penis pumps with other therapies: sometimes penis pumps are used together with a type of drug called a phosphodiesterase type-5 (PDE5) inhibitor, such as Viagra, in a combination therapy. A number of men don’t respond to PDE5 inhibitors alone, so the combination use might be more effective. There’s some research showing that combined use of a PDE5 inhibitor and pump can be very effective in maintaining an erection, and some showing that men who haven’t responded to a type of PDE5 inhibitor did significantly better when they used both the drug and a penis pump.

A medication-free option: penis pumps are a good option for men who don’t want to take medication or don’t respond to them. They’re not, however, recommended for men who take blood thinners (anticoagulants) or have bleeding disorders. Men with Peyronie’s disease ('bent penis') or priapism (when your erections last over 4 to 6 hours) should also be careful if they want to use a pump, and it may not be safe for them. They may also not be appropriate for men who have any skin conditions affecting the penis, any conditions affecting the anatomy of the penis or who have reduced sensation in the penis.
They aren’t the first choice treatment: PDE5 inhibitors like Viagra and Sildenafil are the most reliable, first line choice for most men. They work by increasing the blood flow to the penis once you’re already aroused. The type you choose depends on how often you have sex and how you respond to the drug. Some of the drugs are short acting and are best to use occasionally or when you need. The longer acting drugs can be used in the same way (when needed) or you can take a low dose regularly so you can feel freer to have spontaneous sex (or if you have sex often). These need to be prescribed by a doctor (or pharmacist for Viagra Connect) to check they are safe for you to take.
Penis rings as an alternative: there are some other options that you might want to look at. A penis ring fits on the base of the penis (and testicles) and applies pressure to the area. This slows down the flow of blood away from the penis, so that an erection may last longer. There isn’t any scientific proof that a penis ring can improve erections, but the main benefit of using a penis ring is that it can be used alongside other treatments, such as PDE5 inhibitors. These are not suitable for all men and we would recommend talking to your doctor before using one.
Injections as an alternative: if first line treatments do not help you may want to talk to your doctor about whether you could try an injectable or cream to be used directly on the penis. Alprostadil is an example and it works by making the blood vessels expand to increase blood flow to the penis to help maintain an erection.
Surgical implants as an alternative: a penile implant is usually a last resort, which involves surgically inserting an inflatable prosthesis into the penis. It’s used when there’s a clear medical cause for not maintaining an erection and when other treatment options haven’t worked.
A doctor can help you decide: the best way to choose the right option is to speak to someone qualified so please get assessed through our service or chat to your GP. A doctor can account for your personal situation and approve the right treatment.
