The Oil Pump is a building mentioned by Jace which extracts Crude Oil. It outputs barrels into connected conveyor belt.
The Oil Pump can be overclocked up to 250% speed, at the cost of greatly increased power consumption.

Similar to Miners, an oil pump can be built on an oil node even if the node is completely covered by foundations. The normal extraction rate is 120 resources per minute (requires at least mk. 2 conveyor), 240 resources per minute on pure nodes (requires at least mk. 3 conveyor) and 60 resources per minute on impure nodes (requires at least mk. 1 conveyor).
Perhaps the pipes are in the oil structure and it puts it into barrels - Jace on discord
