With a total cylinder length of 23 cm (9in.) and an inner diameter of 5.5 cm (2.17in.), this high-quality pump gives you ample possibilities to grow in both directions! The total length of the hose is 25 cm (10in.) and the insertion sleeve is made of smooth silicone. Surprise yourself on how big you can get! This variant comes with a plastic pistol grip pump, a cylinder with gauge and a quick release valve for your comfort. There are two versions available: transparent and black!
Clinical studies have proven that vacuum erection devices will give instantly harder erections, cause temporary flaccid enlargement and can increase permanent penis augmentation. According to the American Urological Association, these devices may also be useful in cases where such PDE5 drugs as Viagra have failed to work! Doctors view the penis pump as a safe, effectual and cost effective treatment for erectile dysfunction and state that the prolonged use of these devices will enhance the size of the penis permanently. Other advantages of the PUMPED selection are, among others, delayed ejaculation, improvement of sexual appetite, boosting of testosterone, the maintenance of longer and harder erections and the supporting of penile tissue after prostate surgery. PUMPED, for instant results!
So you’ve decided to get serious.
A penis pump isn’t a toy — it’s a training tool. The right cylinder size isn’t about ego or inches; it’s about controlled progress, healthy expansion, and learning your body’s pressure limits like a lab instrument.
Starting with the wrong cylinder size can mean wasted sessions, bruising, or worse — killing your gains before they begin.
Here’s how to do it right.
📏 Step 1: Measure with Precision
Grab a tape measure or ruler — this is your baseline data.
Length (NBP):
Measure from the base of your shaft (where it meets the pubic bone) to the tip, while erect.
Press gently to account for any padding or fat.
Record that number.
Girth (Midshaft):
Wrap the tape around the middle of your shaft while erect.
Divide by 3.14 to get the diameter (your ideal starting cylinder width).
Example:
If your erect girth is 5 inches → 5 ÷ 3.14 ≈ 1.6 inches → choose a 1.75-inch cylinder to start.
🧠 Step 2: Understand the Science of Fit
A perfect cylinder should be snug — not tight.
When you pump, blood needs room to expand into the vacuum, but too much space means your shaft expands unevenly, or worse, your scrotum gets sucked in.
-
Too small: circulation strain, dark bruising, or a “trapped” feeling.
-
Too big: poor seal, scrotal pull, and lack of pressure buildup.
The goal?
A slow, even draw of blood into the tissue — not a balloon animal.
🧬 Step 3: The Uncut Rule — Why Starting Too Big Hurts Progress
If you’re uncut, listen up.
That foreskin acts like an elastic sleeve — great for sensation, terrible for seal integrity.
When the cylinder’s too wide, your foreskin bunches up and folds inward, making the pressure uneven and uncomfortable. You’ll often see fluid build-up (lymph swelling) at the tip — that’s not a gain, that’s your body saying “too much, too soon.”
Starting smaller helps your skin and inner tissues adapt gradually.
It trains the skin to stay smooth and retract naturally under pressure, without causing fluid traps or donut swelling.
Think of it like lifting weights — you don’t start benching 120kg just because you want to. You start controlled, build form, and level up.
🧠 Step 4: Choosing Your Cylinder Like a Pro
| Erect Girth |
Recommended Cylinder Diameter |
| 4.0" – 4.5" |
1.5" (Small) |
| 4.6" – 5.0" |
1.75" (Standard) |
| 5.1" – 5.5" |
2.0" (Large) |
| 5.6" – 6.0" |
2.25" (XL) |
| 6.1"+ |
2.5"+ (XXL) |
Rule of Thumb:
Start 0.25" above your erect diameter, not more.
⚠️ Step 5: Respect the Curve of Adaptation
Your first 2–4 weeks are for conditioning — not enlargement.
Keep sessions short (10–15 mins), moderate pressure (no pain, no purple), and always use a water-based sealant or lube.
If you’re uncut, gently retract before sealing.
If your foreskin’s tight, work on gradual mobility — foreskin adaptation improves results and comfort.
🔬 Final Takeaway
Pump discipline isn’t about chasing size — it’s about engineering controlled expansion.
Your body responds best to consistent, intelligent stress, not reckless force.
Start smaller.
Build form.
Master your vacuum.
