What Is a Penis Pump?

Penis pumps are devices that are used to increase penis size and combat erectile dysfunction.

They are typically made out of plastic chambers with a valve that controls the amount of pressure inside the chamber.

Penis pumps can use an air or water-based chamber.

Why Use a Penis Pump?

  • Penis Pumps help men get erections.

  • They are the cheapest treatment option for erectile dysfunction.

  • Pumps are non-invasive and are not dangerous like surgery procedures.

  • Gains in girth (especially before sex).

How Do Penis Pumps Work?

Penis pumps work by creating a negative pressure in a chamber to generate a force that expands penis tissue outward.

The pressure is generated by "pumping" the pump, and each pump's kinetic energy is stored as potential energy in the vacuum chamber.

When water/air is pumped out of the chamber, an expansive pressure is introduced that pull outwards on the penis tissue.

This potential energy creates a mechanical force which then proceeds to exert itself on the penis.

Penis Pump Results

Penis pumps can safely expand the penis up to 30% in size.

This size increase will last up to a few hours after using the pump.

Penile Cell Reaction

The body cells in the penis are expanded in two ways.

The first way is by expanding each individual cell size (hypertrophy).

Penis cells expanding in pump vacuum.
The negative pressure caused by penis pumps exert a force on each penis body cell.

As air is pumped out of the chamber, a void is created (vacuum).

That means all the "stuff" inside the chamber has to expand.

The "stuff" is none other than the tens of thousands of penis cells.

As a result, your penis cells are trained to grow.

Frequently Asked Questions (FAQ)

Are pumps safe?

Answer: Yes. When used correctly.

How long do I have to use it each day?

Answer: You should use it for 20 minutes each day.

Are pump results permanent?

Answer: Yes, however, you will have to continue to use the pump to maintain the results.

How long until I see results?

Answer: Most users report size gains IMMEDIATELY after using the pump (temporary gains).

How many times should I pump each day?

Answer: We recommend only 1, and no more.

Will both flaccid and erect girth increase?

Answer: Yes, both will increase.

If I stop using a penis pump, will I lose my gains?

Answer: Yes. You should use a pump at least once a week to maintain your long-term gains.

When is the best time of the day to pump?

Answer: We recommend to pump when you take a shower, to kill two birds with once stone.

Can penis pumps add length gains?

Answer: Yes, to a small extent. The expansive nature of the pump also stretches the penis length-wise.

Will using a penis pump give me weaker erections?

Answer: Absolutely not. In fact, most users report harder, fuller erections.

How old do I have to be to use a penis pump?

Answer: You must be at least over 18 years of age.

Bathmate Hercules

Glamor shot of the Bathmate penis pump.
The Bathmate is a popular water-based penis pump.

The Bathmate is probably the most popular water-based penis pump on the market right now.

But there's a lot of different models with different price points.

This isn't surprising as it is heavily marketed and heavily endorsed by affiliates.

But what's our take on this pump?

Overall, it's a solid water-based penis pump.

But keep in mind, it's the original model.

While it isn't bad, the other Bathmate model pumps are simply better.

Bathmate Goliath

Hercules and Goliath are exactly the same in terms of pressure and pump structure.

The main difference is that the Goliath is a little bigger than Hercules so that it can accommodate guys that won't fit in the Hercules model.

That's it.

If you're in it for the long-run, just get the Goliath since you won't waste money on the Hercules when you outgrow it.

Hercules: for men with 3-5 inches in girth (erect).
Goliath: For men with 5-9 inches in girth (erect).

For more detailed specifics on the Bathmate and what to expect, see our complete Bathmate guide.

Bathmate X-SERIES

The X-Series consists of three models:

  1. X20

  2. X30

  3. X40

The 3 Models of the Bathmate X-Series.

What's the difference between the X-Series pumps and the Hercules/Goliath models?

Good question.

The X-Series pumps have more pressure power and chamber stability.

This isn't surprising given that this model came out a few years after the Goliath and Hercules models.

Overall, they are just better in quality.

I highly recommend getting one of these models if you can afford it - it's definitely worth it in the long-run.

What's the Difference Between X20, X30, and X40?

Same as the difference between Hercules and Goliath: The size of the guy using it!

  • X20 is for the smallest guys - less than 7.5" in length, and less than 5.5" in girth.

  • X30 is for medium guys - less than 8.5" in length, and less than 6.7" in girth.

  • X40 is for already large guys - less than 10" in length, and less than 7.9" in girth.

Bathmate: Hydromax Xtreme-Series

All 4 Bathmate Xtreme Series Penis Pumps
This is a more expensive model of the Bathmate that uses a hand squeeze-pump.

This penis pump provides more pressure power, and we here at PhalloGauge typically do not recommend this pump to beginners who are doing penis pumping for the first time.

The biggest noticable differences are:

  1. The sigificantly larger chamber for the "larger" men.

  2. The addition of a hand-squeeze-pump to increase pressure in the chamber.

While you could get away with using the Xtreme-Series pumps if you're a beginner, the cost is significantly more, so it may be more cost effective to just get the original Bathmate Hydromax (the blue ones).

Ultimately the choice is up to you, but larger men may have to get the Xtreme-Series.


Penomet penis pump glamor shot.
The Penomet penis pump is another water-based pump type.

The Penomet is another interesting water-based penis pump.

Strangely, it has existed even before the Bathmate, but it's not quite as popular.

Functional-wise, it's just as good as the Bathmate - it gets the job done.

The steps required to use the Penomet are practically identical to the Bathmate Original Hydromax model: Fill, and press against your pelvis to get your pump on.

Penomet offers many different types of packages with different accessories.

If you just get the bare-bones basic Penomet pump, you can expect to spend less than the Bathmate at a price point around $127.

How to Use a Penis Pump

Check out our in-depth guide on how to use a penis pump, here.

Here is a quick overview on how to use it:

Filling a water penis pump in the bathtub.

Now that you have your pump here are the steps:

  1. Fill your pump with warm-hot water.

  2. Place the water-filled pump over your penis.

  3. Press the pump against your pelvis to create a seal.

  4. Keep pressing the pump against your pelvis to increase pressure in the chamber

  5. Keep the pump on for 15 minutes.

  6. Release the valve to decrease the pressure, and remove the pump.

  7. Clean and dry up as necessary.

Penis Pump Routine

A daily routine is recommended.

This means getting at least one 15-20 minute pump session in per day.

For those that use the Bathmate or Penomet, this is easily accomplished when you take your daily shower.

Using a timer app on a smartphone to time a 20 minute penis pumping session.
Simply set an alarm or stopwatch timer on your smartphone and leave it near you to ensure you train your penis for the full 20 minute session.

However, if you cannot find time to get in a pump session, try to aim for at least two sessions per week, to maintain your gains.

After you pump, I find it is really good to just "let it all hang loose" for at least an hour.

This means, no wearing tight jeans or underwear after your pump session because this will compress your penis tissue, which is something you don't want.

You want to let your penis relax and not put it under any tension.

What to Expect From Using a Penis Pump

So now you have a really good idea about how penis pumps work and how to use them.

But what can you really expect when you use them?

Here, I give you the crucial insights that you'll be glad to know before you decide to get one.

The sensation - what it feels like on your penis.

Myself, and a lot of other men, would describe the sensation as pleasurable.

That's not surprising when you find out the science behind how pumps actually work.

This pleasure is somewhat between getting a blowjob and masturbating.

I say that because the suction power is many times greater than that any partner can give you.

Not only that, but you physically feel yourself getting bigger because of all the blood getting drawn into your penis by the pump.

Most men experience pleasure from using a penis pump. Another great reason to use it!

However, past this pleasurable level is pain.

Pump too hard, and you start getting pain.

This isn't surprising because exerting too much force on any part of your body starts to induce pain.

Pain is your body's natural survival tool to tell you that something is going wrong.

Knowing this simple fact, you now know when you're pumping too hard and what is the "safe zone" for pumping pressure.

If I had to describe the pain, it feels as if something is crushing your penis. The sheer outward force makes it feel like your penis is imploding.

So don't get to this point. In fact, dial it down a bit to a few levels below this threshold.

The simple fact is, you don't even have to get near the pain threshold to get a good pump in. So risking it is just irresponsible and isn't actually helping you.

Penis Pump Safety

Too much of anything can be a bad thing (just like with everything in life).

The same goes for penis pumps.

Here are some safety rules to follow when using a penis pump:

  1. Do not use a pump for more than 20 minutes during a session.

  2. Do not do more than two training sessions a day.

  3. Always listen to your body - if there is a sharp pain, STOP.

  4. If it is your first time, start your pump training light, and slowly increase the intensity each day / session.

  5. If pain does not go away after a few days or a week, stop using a penis pump and seek professional medical help.

Pump twice a day? Nobody got time for that!.

In Conclusion

Penis Pumps are still going strong as girth-providing solutions for one reason:

They work.

Recent technology has provided us with water-based pumps, a significant advancement of the decade-old air-based pumps.

Whether you're a beginner or veteran to natural penis enlargement methods, you can't go wrong with a penis pump.

If anything, just use it just before sex, and your partner will notice the difference.
