Standpipe

Indeed, thus, things are clear: another mystery solved!
What also appears to me, on examining these photos, is the extraordinarily robust design of these devices with regard to current current production: that suggests ...

good evening, it suggests that it could be a pump given the robustness of the terminal, as it could be a simple valve with a little mechanics, something that I would find strange, since as said before a push button was enough damage that the company bayard gives no explanation of how it works

[Forhorse]

no because the push-button or the steering wheel to turn do not have quite the same function.
The push button is instantaneous: you press it flows, you release it stops. Convenient for drawing water, but for washing your hands how do you do it?
The steering wheel terminal allows a time delay: we turn it flowing, we release it customary to turn by inertia for a certain time allowing the water to flow at the same time.

Anyway the photo of the mechanics leaves no doubt, it is not a pump.

good evening, too bad it is not a pump, it would have been nice, actually I had already operated a terminal like that we do not need to turn it is enough to give a little boost and hop it turns for a while

what made me think of a pump is a guy told us that there is a sheet of water underneath which this fire hydrant draws by turning the wheel, or so he told us anything what

it was at the strasbourg christmas market

hello, there are two types of push button that one pushes or it flows when you release it stops a bit like the urinal pushers of some toilet flush without tank

there is the push of the sinks in the public toilets you push the button which remains pressed for a few seconds while washing your hands, and which returns by itself to the initial position

so some standpipes have the second type of push button

slim someone I know lives in the countryside have a small sheet of water in which they draw with an arm pump, the latter being broken, they want to use a fire hydrant to associate it with a vertical wind turbine, I hope they did not buy the terminal on ebay, as I advised them

these are siphon terminals the one whose cap turns

hello ,, the person who wanted to replace the arm pump with a fire hydrant, still bought one on ebay at 150 € if it is not a pump, he will throw this money out the window, this one me said he bought it in the first week of January, but didn't have time to mount it with a soapius type wind turbine

I saw this kind of fire hydrant when I was little ... I do not know exactly what is inside but I imagine a centrifugal pump at very low pressure which only pumps a few centimeters higher water which arrives by the supply, the level of which is limited to a few centimeters below by a float type flush valve

[chatelot16]

I imagined a centrifugal pump, but if you saw on the ebay description (which is no longer visible) a centrifugal mechanism which opens a tap, I will not contradict you: it is quite the function: as long as it turns it opens and it flows: it can turn long enough because it does not consume energy

my hypothesis of centrifugal pump and float valve is not the right one

hello, i would find rather ridiculous a flywheel valve, a timed push button seems more proportional to me, i still think of a pump but which goes up the water from a low height

if the ebay link is no longer active it may be the person I mentioned above who bought it, ouch I already see the disappointment, especially since I told him about these fire hydrants, I did not imagine that he was going to buy the one on ebay

[oli 80]

good evening, I also saw taps with timed push buttons, so we push, it flows for a while then it stops, so this system must undoubtedly exist on the fire hydrants, moreover it is there that simple or timed push valves appeared

on the other hand i have never seen a flywheel tap, so check out this site http://belcikowski.org/ladormeuseblogue/?p=922

it would be enough to solicit the webmaster, if already on this site they speak of pump it is that they have already dismantled it
