AMS pump issues

Postby sambalamba » Mon Jan 05, 2026 12:20 pm

I’ve been doing some digging into AMS pump issues. From what I can tell, there are two distinct mechanical issues:

1. "Pump Stiction" (The Classic Stuck Bulb): This seems to be the most common issue. You squeeze the bulb to inflate, but it stays collapsed (depressed) and won't recoil back to draw in more fluid. It feels frozen flat. This often happens after the 4-6 week recovery wait. The internal valve pin sticks to the silicone sealant ring due to static friction ("stiction") from sitting idle. Surgeons often try a "forced deflation" maneuver in the office to pop it free, but sometimes it requires a revision.

2. "Endless Pumping" (Valve Seating/Bypass): I’ve seen reports (and a recent discussion here) about guys pumping 50-70 times and never hitting the "marble" or the hard stop. In this case, the pump bulb recoils fine, but you never reach max pressure. You are moving fluid, but the system doesn't lock out. This is likely a check valve bypass issue where the internal valve isn't seating perfectly between squeezes, allowing fluid to slip back or preventing pressure build-up.

How many of you have dealt with the either of these issues?

sambalamba, probably need to distinguish between the older MS pump and the newer Tenacio pump. I have the Tenacio and haven't experienced either of those issues.

I have the pump that AMS has been using for over 20 years and it works wonderfully, the Titan Touch pump was softer and inflated faster, the problem is that it did not deflate as advertised, it never deflated or it reinflated after a few minutes, the AMS pump inflates more slowly but when you press the deflation button it deflates and locks perfectly, what the Titan Touch pump should do it does not do, the old AMS pump does it very well, another thing with the Titan I was 15/15.5 cm long and 13 circumference, with cx I am 16.5/17 and 13/13.5, the Titan was 22 and the cx is 21, in my opinion, and it is as I say and not the implantologist, the reason is that before having the tips too far forward it strangled my glans in addition to having at least 1 cm more silicone in my cock, now it strangles it less, but it should have put them even lower by another 1 cm, unfortunately glo implantologists never admit the mistakes they make, in fact I have never read on this site that a doctor has admitted his mistake, fortunately the ams tips are more rounded and do much less harm than the titan tips which are very sharp

Hey Frank, Good to hear that you're enjoying life with your AMS. You're right about the tips of the AMS vs Titan.

TitanVsCX_Tips1.jpg


Above is a picture of the AMS vs. Titan tips.

Good thing about Titan tips:
1) Smaller.
2) Bends at a more acute angle. Conforms to the human corpora tips more
3) Good for glans support as it can be inserted almost to the distal corpora tip

Bad things about Titan tips:
1) The tips are harder. So it presses into the glans tissues more
2) A bit less round. But since the tip has a overall smaller footprint, pressure per unit area of the tip is higher.

Good thing about AMS tips:
1) Softer. If you look closely there is actually an airgap in the tips.
2) Exerts less pressure per unit area of the glans

Bad things about the AMS tips:
1) Larger area. Can be felt on the side of the glans more
2) Due to larger area may be difficult to get it all the way to the distal corpora tip

Just wanted to share

I've had both issues with my MS pump but for me they are insignificant. Rarely will the bulb stay collapsed on first pump and pressing the release but corrects it. I had the endless pumping early on but rarely happens now and firm fast pumping fixes it.

I've only had my AMS MS pump for 10 months but it has worked flawlessly.
I have never encountered either of the problems stated.

I have been cycling for almost 2 weeks and in the last week have noticed both of those problems. Generally, if I’m really active during the day, when I go to cycle at night, I have the sticky pump issue. When I cycle in the morning after a night’s sleep, it’s fine, no sticking. So that would support the theory that it has something to do with movement and static electricity build up. And I’ve been able to release it and reset the pump every time by pressing the deflate button and pumping again.
As for the “forever pumping,” I only get it if I pump in a particular angle from the “back” of the pump (in relation to its position in my scrotum). So that angle must somehow cause the valve not the seat correctly and result in backwards leakage.
In either case, no big issues in my opinion. Assuming they don’t get worse, I can live with them.

I haven't heard of anybody having the endless pumping issue with the AMS as an ongoing problem. My personal experience was that it resolved after a cycling for a week or so, I have written on FT that my first experience getting "the marble" was when I cycled in a very hot tub, and I linked that environment with something in the pump being warm enough to seat. I mentioned it just in case another guy had the same concern, I hadn't seen it mentioned on FT prior to my surgery.

That could be nothing but coincidence though. It could be that the pump just needed time to break in. When I mentioned the never ending pumping to Dr. Clavell, he thought it was of no concern, he just told me to keep cycling. I have experience with exactly 1 pump, he has experience with thousands.

Are there guys here that have the AMS MS for a period of time and still can pump and never get the marble? Even at the very beginning when that was my experience, I was completely able to have PIV sex.

I used to have the “endless pumping” issue, but now no longer do. Likewise, on my journey to regain length, I never achieved the “marble pump” either. Now, when I’m max inflated, the pump just flattens—that’s it: no more fluid in the reservoir. I don’t believe this is atypical for guys who have maxed out the implant. In any event, the device works fine.
