Deep Mechanical Fluid Pump

The Deep Mechanical Fluid Pump is a fluid-handling building that moves water (and other fluids) from one side of the pump to the opposite side without producing drinkable water. It creates a direct transfer rather than treating or filtering the fluid, and when discharging into a one-tile-wide canal it produces a flow of 0.5 cubic meters per second (cms).

The pump was originally introduced in Early Access as the Deep Mechanical Water Pump and was later renamed to Deep Mechanical Fluid Pump. It discharges its output one block lower than older versions did. Shafts can only connect to the pump from its two shortest sides.

• Current maximum pipe length is 8 blocks (this was increased from 6 blocks in a later update). Earlier material stated a maximum pumping depth of 6 tiles prior to that change.
• The Deep Mechanical Fluid Pump must be constructed with specified component counts (listed as 100, 50, and 50 in construction references). Unlocking the pump requires 5000 research points.
• When placing the pump, the blocks under any attached pipes must be at a lower level than the tile where the pump is built.
• Power and shaft connections must be made to the pump from its side block; attempting to attach power via the pump side or pipe side will not power it. It is unknown whether power supplied from beneath the pump (for example, by placing the pump atop a rowhouse) will power the unit.
• The pump no longer stops flowing fluids in normal operation and is buildable on any stackable building rather than being restricted to levees.

Practical notes for use: position the pump so there is a clear side-to-side fluid path and ensure pipe elevation rules are respected. Use the side block for mechanical power input and avoid relying on pipe-side or pump-top connections for power. The pump is intended for moving bulk fluid across vertical separation rather than producing potable water.
