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 at a rate of 5 iridium per second.


The Well Pump is an excellent extractor of iridium early and late game. Typically, bases that 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 the only upgradable structure in the game, with three upgrade tiers available. Upgrading the Well Pump will add a built-in Fabricator, a built-in Distributor, and extra pumps to triple the Well Pump's iridium output.

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
