Pump

Small pump/infobox A Small Pump (when powered) moves fluids from its input to its output and (regardless of power) prevents the opposite from happening. This happens even if the pressure of input is much lower than the pressure of output (although speed may be affected). Note that the pump can't mix different kinds of liquids.

The small pump can be seen as the inserter for liquids.

Throughput (needed number of pumps)

The throughput depends on the pressure difference between input and output.

In the worst case (no input pressure, max output pressure) you need 5, better 6 small pumps, to fill a pipe to its max throughput.

Using as Valve

The small pump works as a valve:

• When powered, the small pump will let liquids through, but only in its set direction. The throughput depends on the pressure, see above.

Tip: You can just rotate the pump to "switch a pipe off". This is sometimes handy.

• If unpowered, the small 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.
