v0.31 Talk:Screw pump

Note: Pumps will transfer power vertically as they did in 40d. It is confirmed they function in all respects as they did in the previous version. For information on vertical power transfer see Pump Stack in the article.

About the service area in the picture. You can use a door at the impassible part of the screw pump instead of using two doors. The dwarves can dig and move diagonally. --Altaree 15:38, 13 April 2010 (UTC)

it can be ... operated by ... using gear assemblies connected to water wheels and/or windmills.

A gear assembly is not necessary. It is possible to build a water wheel, connected to a horizontal axle, connected to a screw pump. The screw pump will function as intended.

Pump Speed

How much water do screw pumps move? Is it 1/7 of water per game frame? If you wanted to build a 1x1 waterfall that operated constantly without sourcing any new water, how many pump stacks would you need?

A lot. I don't know. Less than one, so to speak ;) In any case, channel the water through a diagonal after the pump --92.202.29.45 17:16, 22 April 2010 (UTC)

I believe they move 7/7 per step. Make sure your drainage is good :) 66.30.8.88 21:27, 26 April 2010 (UTC)

Magma-Safe Pump

How is it possible to make a magma-safe pump (or rather, one which does not degrade into its component parts), since pipe sections and corkscrews can (apparently) only be made of wood? Rodya mirov

• Nevermind, pipe sections and corkscrews can be made of metal, just not rock. Leaving this here in case anyone else has a similar concern. Rodya mirov

The entry implies that you can pump magma with a pump containing some wooden parts. This is very misleading because while you can fill an area on the other side of it with some magma, the pump pretty much instantly catches on fire, and within a couple minutes will fall apart.--Krenn 06:40, 9 May 2010 (UTC)

Desalinating water

Can someone add an idiot-proof explanation for how pumps desalinate water? I can't get it to work.

Here's my setup:

(saltwater lake)
  %

╔═0%0 ║+++║ ║+++║ ║▲++║ ╚═══╝

▲

Pump pumping north to south from the lake, ramps put in for access while constructing, floor built under first tile of the pump. When I order the pump to be started, the reservoir gets filled. I stopped the pumping before the reservoir overfilled, then designated the level above as a zone. Water source does not highlight, and designating it doesn't work.

Initially I did the above but had not built a floor tile under the exit end of the pump, which did not work. I removed the pump, put in the floor, waited for all the water to evaporate and tried again - no dice. Does that mean mud will contaminate the water and make it salty?
