Water Pump

The Water Pump is a Steam tier multiblock that produces water from steam at a rate proportional to the humidity of the biome and the tier of the machine: basic (T1) or high-pressure (T2). The Water Pump is a direct upgrade to the Water Tank because it produces water significantly faster, although not for free. It requires 1,500 L/s of steam as input to produce up to 3,600 L/s of water until the output hatch is full. The Water Pump is incredibly net positive on water because producing up to 2L of water for every 1L of steam is a much better ratio than boilers consuming 1L of water for every 160L of steam. The Water Pump is superseded by the EnderIO reservoir and the Thaumcraft Everfull Urn in HV.

Construction

The Water Pump is available in two tiers, but the only structural difference between them is the material of the frame boxes. Buses/hatches may replace any casing anywhere on the structure. Steam is only accepted through a steam hatch (NOT an input hatch), much like other steam tier multiblocks. Use the Multiblock Structure Hologram Projector to visualize/build the structure where the projector stack size determines the structure tier (1=Basic, 2=High-Pressure).

Assuming plates are made with a hammer and rods are made with a file, a basic Water Pump (with the necessary hatches) requires 156 bronze ingots to build. A high-pressure Water Pump requires 80 steel ingots and 76 bronze ingots to build.

Basic (T1)

Controller: Front bottom center
10 Bronze Frame Box
9 Primitive Wooden Casing
1 Steam Hatch: Any casing
1 Output Hatch: Any casing

High-Pressure (T2)

Controller: Front bottom center
10 Steel Frame Box
9 Primitive Wooden Casing
1 Steam Hatch: Any casing
1 Output Hatch: Any casing

Wallsharing

Water Pumps may wallshare each of their sides to save on primitive wooden casings, frame boxes, and hatches. However, only one is really necessary anyway since its water production rate is so high.

Usage

The Water Pump consumes a fixed 1,500 L/s of steam as input and instantly converts it into water. The exact amount of water produced depends on the humidity of the biome and the tier of the machine, as seen in the following equation and table. The values for a Water Tank with clear weather and direct sky access are provided for comparison.

The Water Pump does not require direct sky access, and is not affected by snow or rain. Do not forget to disable void mode in the GUI of the controller to prevent excess steam from being consumed if the output hatch is full.

The water to steam ratio in the Water Pump is much higher than the usual 1L for every 160L in boilers, which creates a net positive amount of water regardless of biome humidity. The water production rate is also more than enough to support multiple Railcraft Boilers or Large Boilers. For example, a basic (T1) Water Pump in a biome with only 50% humidity supports up to four maximum size, high-pressure Railcraft Boilers running at maximum heat.
