The Well Pump is an Extractor. It must be placed on a Well Pipe and once built will pump iridium from the Iridium Ocean to its output pipe.


The Well Pump is an excellent extractor of iridium early and late game. Typically, bases which employ many Well Pumps for their iridium supply are called 'Sprawl Bases'. Additionally, all Starter Islands generate one well pipe, making the Well Pump an excellent choice for a starter base's first extractor.

Well Pumps are also the only upgradable structure in the game. Upgrades to the Well Pump include a Fabricator, a Distributor, and extra production.

As of December 23rd, 2018, this and other extractors now have a display showing how much iridium they are producing each second.

As of April 5th, 2019, the Well Pump and other extractors produce a sound effect.

Pros & Cons


  • Very cheap for the amount of iridium produced
  • Can be upgraded for extra functionality


  • Can only be placed on well pipes, which may be sparse or located in an unideal position. These well pipes can also be destroyed by Explosives.
