Pump

Small pump/infobox A Pump is a multipurpose fluid handling device which can be used to move fluids, perform flow control, prevent back-flow and load/unload trains.

The pump can be seen as the inserter for liquids.

Using as a Pump

When connected to pipes on both ends of the pump and powered, the pump will transfer fluid from the source side to the output side if it will fit. This will occur even if the input side has significantly lower fluid levels.

Note that the pump can't mix different kinds of liquids.

Using as Valve

The pump works as a valve:

• When powered, the pump will let liquids through, but only in its set direction.
• If unpowered, the pump doesn't let anything through.
• If the pump is powered but has a circuit condition, it will only let fluids through when the condition is met.

This can be used to control some parts of your factory. For example, with a single wire from a Lubricant tank to a Small Pump pumping Heavy Oil, you can disable cracking Heavy -> Light Oil when Lubricant is needed.

An example, which uses some useful properties of the pump, can be found on the forums.

Loading/unloading fluid wagons

Pumps can load and unload fluid wagons at train stops. When a pump is placed with either end facing a rail track and the other end connected to a pipe, it will visually change. When a fluid wagon is stopped adjacent, the pump head will connect to the top of the nearest tank and begin transferring fluids.

Prior to version 0.15.0

Small pump throughput was an issue and often required multiple paralell pumps. Throughput testing and pump array designs can be found on the forums
