The psychofluid pump is a building added by the Biotech DLC that improves the psychic sensitivity and psycasting ability Content added by the Royalty DLC of a deathrester.


Psychofluid pumps can be constructed once the Deathrest research project has been completed. Each requires Steel 50 Steel, Plasteel 100 Plasteel, Component 6 Components, Hemogen pack 5 Hemogen packs, 4,000 ticks (1.11 mins) of work, and a Construction skill of 4.


Active psychofluid pumps require a pawn capable of deathrest, and must be connected to a deathrest casket. Each psychofluid pumps consumes 100W of power and Hemogen pack 0.5 hemogen pack per day as long a pawn is deathresting in an attached casket. It can hold up to 5 packs at a time, for a maximum run time of 10 days, and is constructed fully fueled. The pump will be automatically refueled by a haulers so long as auto-refueling is enabled. They also do not consume power while idling, unlike facilities such as sleep accelerators.Content added by the Ideology DLC Hence, they can be left idle without consequence.

A functional pump grants 1 stack of Psychofluid Rush after a pawn wakes from a non-interrupted deathrest. Up to 4 psychofluid pumps can be connected at a time. The bonus will be lost if deathrest gene is removed from the pawn.

    Like other deathrest buildings, a psychofluid pump permanently binds to a pawn once used, with no penalty for deconstruction. Deathresting pawns have their own separate limit to the buildings they can connect to, which can be increased with a deathrest capacity serum.


    As with all other deathrest machines, these cost a non-negligible amount of steel and components. Consider holding off on building them until you are more well established and are able to produce steel and components reliably with deep drills and fabrication benches. The psychofluid pump also requires plasteel, making it one of the more expensive deathresting machines.

    The main purpose of a psychofluid pump is to increase the potency of psycastingContent added by the Royalty DLC or psychic harmonizers.Content added by the Royalty DLC Without the Royalty DLC, the uses for a psychofluid pump are rather limited.

    For psycasters, the buffs are significant both in individual power and the density of different benefits given a single source. Best case scenario, a focus-less meditator, the bonus to meditation rate from 4 pumps cuts the meditation time by −29%, reducing the time from 0% to 100% psyfocus by 0.57 days. For a super psy-sensitive psycaster with the best possible focus, the relative improvement of 4 pumps drops to −15%, reducing the time from 0% to 100% psyfocus by 0.13 days. This is still a significant buff.





    In the game's files, the psychofluid pump has a separate north facing sprite, despite it being identical to the south facing sprite.
