I heard from an other pumper that you can use a kind of "blind flange" to shut-off the single-end hose. He has see a kind of cone used, perhaps made of aluminium. The cone was fitted to the hose (without end fitting) by pushing it inside the hose. And then there were small holes in the hose end and in the cone. Cone was fitted with a kind of pins to the hose. What kind of system this is? I tried to search in google, but didn´t find any matches. Does someone know? Where you can get such cones?

Putzmeister Pin-Pour ?

I don´t mean pin pour. Pin pour needs to be attached to a hose end (to metal parts). So it is not suitable for single-end hose. And it won´t shut-off the hose, it just affects to the better flowness of the concrete.

What I´m searching for now is a kind of "blind flange", which has "cone shape". It closes the hose. So you don´t need any shut-off valve etc.

Something like this one ? or the "stoneage" !

Have you been shopping in the sex store again I thought you kiked that habit....lol say hello to Timo for me

Hi Chris ! I never buy anything... They sends things to Me (freebees) and hope I shall think that theres products is "the best" In the market , so We buy it to all our other pumps !

Hey Vasa ,

 Those both look homemade ? You may want to put a patent on them lol

Both are very clever ideas .

Those hose pinchers were pretty handy for the experienced.With that being said bbcp banned the use of them for obvious safety reasons.

Both look like good ideas but the ones that pinches the hose aslo breaks the wires in the hose, whitch make the hose have a weak spot on it and in a plug situation the weakest area goes first. Not to mention you swing the wrong way and your laborer becomes a shishkabob. I like the other one. Very simple. We took go devils or rabbits when they were no good and cut them in half and run a bolt threw it with washers on each end. Worked good to stop the dribble.

Vasa, what are the white parts of that compression plug made out of?  My first thought was thast they looked like ceramic, but that can't be, then I thought HMW plastic.

And the rubber?  Is that a scavenged part?  Or just some type of soft rubber so that it readily expands when squeezed?

Thanks Vasa for good photos! This "plug" is what I mean. But I heard from an other guy that there are aluminum cones which are kind of plugs somewhere. He had seen a picture in internet, but he doesn´t remember what was the name or address of that page : (  There are holes both in that cone and in the hose. And you put a kind of "safety pin" to that hole, so the cone-plug stays inside the hose. Anyone seen that kind of system?

My 2-cents on shut-offs, anything physically closing off the hose, either from the outside (such as a pinch valve which have been around since the beginning of pumping-time), or inside the discharge end (such as any type of plug) have the potential for catastrophe.  They may work, but if they are not removed before the pump is started-up, you're going to find the weak link in your system & something's going to give.  This is why an air shut-off is so safe.  If you close off the line with 90 PSI (max) air pressure, & you forget to release this air pressure & start your pump it will compress the air & push the concrete past the valve as soon as your line pressure hits something over that 90 PSI air pressure.  Nothing can fail catastrophically (unless you're running 'see-through' pipeline on your boom which is dangerous on its own).  I really hate to see these kinds of shut-offs being used for safety sake (my opinion)

My operator puts a piece of plastic bag material or like a 1'x1' piece that you cut out of a tarp over the end of tip hose, then slides a rubber seal from clamp over it and up onto the tip hose.  Works pretty slick to keep tip hose from dripping while slewing over no-mess areas or folding pump up.

  TOM@CF    Do you sleep better if you knew that I run with an aircuff since 15 years back ? Not Conforms but another brand... The plug have I to stop the dripping of mud when I move the pump... The other device on the pic , we stoped to use 15 years back... It's funny , you can go to the moon in USA , build atomicbombs and be the "worldpolice" but buy an air-cuff to a pump or OSS is nearly impossible ! .

Try stuffing an 'oversized' ball up there, works great to just stop dripping. And a bit safer.

The "plug" comes from Putzmeister..... And what is so dangerous about the "plug" ? The most "tools" are dangerous on a buildingplace.... If it is used in a wrong way !
