I have a device that's supposed to make magma bubble up through grates in the floor. Pumps raise the magma from a cistern to the magma chamber's level, but it falls down into a second cistern below the chamber. Will the pressure from the pumps push magma upward into the top area?

I've set it up like this:

Where P> or <P is pump going in the direction of the arrow
# is a floor grate
_____________________
_enemies go here_#|  <P |
|_________________|P> |
|~~~~~~magma~~~~~~|

The pump should pump the magma up to the same Z level as itself, so your design should work.  IF you want to make double sure, make that pump stack a couple levels taller and you should be filling that room for sure.

hey glados!
well, you know what we always say, when i doubt !!science!!

I'm patiently waiting for Toady to put in Baking, so we can have Cake now that we have milk, eggs, flour, and sugar...

Ah yes, the dwarven "magma bakery".

There's really no other way to implement it, I'm convinced.

«nd then make a aperture science fortress filled with deadly traps, pressure plates and more and hide the cake after the ever lasting fire

[DrKillPatient]

Well, there is a dodge-this trap just before the Urist !!Science!! Magma Murder Device, so I could toss some down into a labyrinth of test chambers... Hm. I think I'll do that, actually. That is, if I survive the Fortress Defense mod long enough D=

It will work. I raped one of my own forts with an accidentally similar design (except my magma was pressured to five Z-levels above the surface...)

I was going to make a thread on this, but I'll post it here since its the same idea.

 I have a setup like op's that doesn't work, I have hatches along where the enemies walk linked to pressure plates so that the hatches spring open to the magma level and in theory 'should' act like mines and release the 'pressurized' magma

When the pumps are manned, and enemies walk onto the hatches, all that happens is the hatches open, and the magma doesn't rise up like I thought it would. My area is pretty big, so made walls and snaked the magma cistern underneath the hatches. I also increased the amount of pumps - its now 3 on each level. I tried it with all pumps drawing from the same cistern, then I tried it with two - one below the first pump and the one above pumping into a separate one beneath the hatches

Neither works, the magma is 7/7 everywhere in the system, the top level doesn't seem to be drawing the magma from the pumps below.  What is going wrong?

kendo: the problem is that your pumps are feeding directly back into the magma cistern, so there's nowhere for the pressure to "build up" and force it out of the hatches. If you want that to work, you'll need to make sure that the pool of magma underneath the hatches is not connected to your pump intakes.

Also, in the future use [code][/code] tags for your drawings.

I, for one, would love some cake made out of purring maggot milk, cave wheat flour, elk bird egg and sweet pod sugar.

That was my first idea why it didnt work. I had it all coming from the same source originally but now my z - 0 level pump is drawing from a separate cistern than my z +1 pump is.
