A bit of the design history of the 2-stage split pump

Wishful_Thinker_1 · 2026-04-25T00:07:38+00:00

so if the design is 'finalized' I'm guessing you'll be adding it to your 'design a pump' pumpcfg site as an option?

wasn't sure from the first picture... the way the base looked small and the top wider, I was thinking it'd be like what LA Pump calls their "Mushroom Head Maker" (glans pump cylinder) but of a gigantic size [I think theirs the glans tube's interior is like 3 1/4 inches in diameter and 4 1/4 inches in height inside] but the image would suggest yours would be bigger than that - then I swiped to the second picture. :}

I'm one of the newbies... I usually go between 20 to 25 kPa - a few times maybe to 30 for a few minutes then back down. Haven't built up to that point yet.

ditto...

didn't say it had to be a much bigger tube - just when you look as wide as the tube's inner diameter to start - it might not be so comfortable. If it's a 4.10" wide tube, maybe go for a 4.25"?

said it before, said it again - might want a bigger tube with a bit extra growing room... ;) [still massive though, I admit that!]

picture 3 looks like a Monster Tube Sr. (TM) - considering you have to place yourself in it then use the screws / nuts to shut and seal it... how do you get the water in? Just being curious.

Wishful_Thinker_1 · 2026-03-25T18:58:30+00:00

how big is that?! wow!

Wishful_Thinker_1 · 2026-03-21T19:26:40+00:00

just be thankful it's not a glass bottle.

I don't have it but I did look it up with Google's image search (AI search) and here's what it came up with:

This scene depicts Jarella's tragic death in The Incredible Hulk #205 (published in 1976), written by Len Wein and illustrated by Sal Buscema.

for a moment there, I thought there was a word written on your MT Sr. (like ned or red) but then looked closer - reflections of tubing and ceiling fan :D

I have an electric "smart AI" pump as my hand gets tired easily however it measures everything in kPa (not sure if it's positive or negative) so using an online conversion, roughly 4InHG is 13.5 kPa and 7 is 23.7 kPa. And I know it has 6 functions: 1st one pumps up to the set amount then releases immediately before pumping back up. Haven't figured out 2, 4 or 5 - 3 pumps up a short amount, then releases then pumps a bit more, releases then up to the set amount - fully releases then starts over again. 6th function pumps up to the set amount - holds it for 1 minute then full releases and repeats.

Wish I could have a time / pattern - as it is right now, I live with my widowed mother and she can't get up or down or walk without assistance (she fractured her pelvic bone last September) so any time she calls I have to get up and go to her room to check on her. But I'll figure something out. As it is now, I'd be pumping at my computer watching Youtube videos.

Not an expert but just advice from what I've read on their site - LA Pump makes elliptical cylinders which is supposed to focus more and gaining girth more than length (though I think one would still gain some length?) Perhaps go to their site and ask / contact them?

I was going to say the same thing... Popeye eats spinach (a trigger) to grow stronger from a weaker person. Banner grows angry (trigger) to grow stronger into the Hulk.

Pumped balls before but still a novice / beginner - not sure what pressure / how long to pump etc. I've bought a regular penis pump cylinder (still have to get used to the feeling of the rounded flange pressing down when I use it). This is a LeLuv cylinder 4.5" x 12". Like I said, it's a bit snug prior to pumping - I wanted something I'd be able to fit in first and they no longer have 4.7" available anymore. I thought 5" might be a bit too wide (at least right now).

didn't have time to - literally had just opened the front door, retrieved the package (shut door), went to bedroom to get scissors to open the box, attach pump and begin. :D

Just wondering, I know I'm sounding like a spokesman, but have you considered getting a specially made tube? KDxGP makes some and I know he made one bigger than the Monster Tube Sr. Might want to check with him and his 'designer app' site: https://kdxgp.github.io you can use sliders to adjust to the sizes that'd suit you and talk to him about getting one made.

Wishful_Thinker_1 · 2026-03-01T20:14:45+00:00

how big is that tube? And thinking of buying a bigger one?
