Inlet and Outlet Pumps are mechanisms used to transport Water, Lava and Honey, without having to construct pathways through Blocks, or rely on gravity. Instead, an Inlet and Outlet Pump need only be connected to each other with Wires and activated, which transfers fluid from the Inlet to the Outlet. Each activation transfers up to four tiles of liquid. For continuous automated pumping, a Timer must be used.
Despite its appearance as a pipe that takes in liquid from beside it, an Inlet Pump must be submerged in liquid, as it removes liquid that lies directly over its graphic, and does so equally from all of its 2x2 tile space. Similarly, an Outlet Pump spawns liquid directly over its graphic, and does so equally over all of its 2x2 tile space.
- If the Outlet Pump becomes completely submerged, it will stop pumping.
- When used to transport Lava, a Pump already submerged in Lava cannot generally be retrieved again without destroying it, as the dropped Pump item will immediately fall into the Lava. Lava must first be drained in order to retrieve the Pump.
- When activating an Inlet Pump that is submerged in a body of liquid, slightly more liquid will be pumped out than is taken in. Using a Timer, this effect can be exploited as a liquid production method. See also: Guide:Making liquid.
- Multiple Inlets and Outlets can be connected using a single path of Wires. The fluid transfer rate is increased accordingly, without the need for additional Wires to act as "pipes".
