Screw pumps should suck up animals and chop them into little pieces.  The enormous corkscrew in it would kill them.  The screw pump might only be powerful enough to suck up small animals, like puppies.

That would be an epic Kitten-Smiter.

Designate a channel to be a pit, hurl the kitten in...

[Ihlosi]

Sure, if you can get a dwarf to turn them at a few hundred rpm ...

Otherwise, they won't create a lot of suction. Something would actually have to be caught in the screw in order to be pulled into the pump.

Make a few dozen windmills, then. Maybe even throw an elf in when they siege you for cutting down all the trees to make the windmills.

[Jothki]

Aren't screw pumps fairly passive?

[Sukasa]

At the rate *they* spit out water when mechanically powered?

Hell no man, those things are deadly!

Boohya. Serrated enormous wooden corkscrew + Goblin = dogmeat. Make this now.

[Tahin]

Meat grinders! Throw whole litters of kittens in, and out comes *Ground Kitten Meat*.

if you look at the way a basic screw pump works its impossible that anything above a few inches (or the distance between turns of the corkscrew) would get in, or that anything bigger would be in the least bit harmed by sticking a limb into the pump. The idea of having sharp serrated edges of course could help things get in in few inch chunks at a time but the pump would have to be spinning much faster than a hand pump would to cut through bone and muscle, several windmills with a gearing system maybe. We dont have a way of making pumps use more energy to increase their speed though.

Killjoys.

U-turns generate infinite magma! Dwarf Fortress DOESN'T MAKE SENSE ANYWAY!

LOL, AWESOME idea for a trap!

"Spiked Rollers"

Its entrance is from the top via trapdoor at z-1.
The trap, two counter-rotating rollers (giant corkscrews), is on "z".  Anything that lands on the rollers takes numerous pierce and crush attacks before being spit out the bottom.
Its exit is to the level below, z+1, so enemies take a fall when they're spit out.
Non-metal items come out "mangled".
Metal items have a chance of jamming the trap.
This is a powered trap.  Unpowered or jammed its upper level behaves like floor and the roller level behaves like vertical bars over a floor grate.

The problem with the trap is I don't think there are any constructions except ramps which are built across multiple z-levels.  You might have to dig a channel above it, then install the machine and its "ceiling" is the trapdoor, like how constructed walls work.

Edit: Clarified "rollers" are build from 2 giant corkscrews

If you could build traps on a bridge, you could build the equivalent today: bridge at z+1.  Retract the bridge to fall on levered spikes on a bridge at z.  Put the z+1 bridge back (in case anyone's left up there), then retract the z bridge to retrieve the goodies.

I suppose "levered spikes" could be "ballistas on either side" and then the whole thing works.

And also make giant powered meat grinders: 1 grate (Grate is actually used to squish meat through it.)+ 1 giant metal corkscrew + 2 blocks, looks like pump %% 1 light 1 dark tile, basically everything 1z above dark tile gets sucked in and then falls out as meat(probably apply the same rules as for rollers suggested above) on the same z level as the grinder from the light side, make butchers happy

Hi!

Well, in that vein, how about having a useful setup between a kennel, a screw pump and an smithie?

Put in one dog and a bar of tin, and you get 5 cans of cat food (2 cans if you use a puppy). That is definitely something useful.
