Pumps

Pumps are a new game mechanics addition for liquids transportation which was introduced in the 1.1 update.

To use pumps, an Inlet Pump must be connected to an Outlet Pump using wire. When the wire is activated, a small amount of liquid is removed at the inlet and created at the outlet. For continuous pumping, a timer must be used.

Pumps can be used to transport lava as well as water. However, a loose pump floating in lava will be destroyed, making it difficult to relocate them.

It is possible to create infinite water using pump by pumping water in an infinite loop. If the inlet pump is placed at the bottom of a large enough body of water (50+ blocks or passed rendering field of screen), no water will actually be removed when it is activated, but the outlet pump will still produce water.
