Pumpjack
The rhythmic heartbeat of the factory, drawing black gold from the earth to fuel progress.
The Pumpjack is a fundamental piece of industrial infrastructure in the Factorio universe, serving as the primary interface for extracting crude oil from underground reservoirs. Unlike other machines that process resources or generate power, this device sits directly atop an oil patch, rhythmically moving its mechanical arm to draw the black liquid to the surface. It represents the first step in the complex chain of petrochemical processing required to fuel a growing factory.

Lore & Background
As factories expanded from small outposts into sprawling industrial metropolises, the Pumpjack became the most common sight on the horizon of every oil-rich sector. These machines operate in unison across vast fields, creating a hypnotic, synchronized dance of mechanical limbs against the alien sky. They are the silent workhorses that feed the refineries and chemical plants, turning raw, unusable crude into the essential fuels and plastics that drive civilization forward.
In Their Own Story
The wind howled across the barren plains, carrying the faint scent of sulfur and ozone. Engineer Kael adjusted his goggles, watching the rhythmic clank-clank of the new Pumpjack installation settle into its cadence. It was a lonely sound in the vast silence, yet it promised life to the dormant factory behind him. With every downward stroke of the beam, dark fluid surged up through the pipes, a lifeline flowing toward the waiting tanks. The machine didn't care about the alien insects skittering nearby or the strange stars above; it only cared about the oil beneath its feet.
Reader's Guide
The Pumpjack is a passive extraction unit that requires no power to operate. It must be placed directly on top of an oil field, indicated by dark patches on the terrain. Once installed, it immediately begins pumping crude oil into connected pipes at a rate determined by the richness of the specific patch. There are no crafting recipes for the Pumpjack itself; it is crafted in the assembly machine using iron plates and gears. However, its output requires immediate management via fluid logistics. Players should connect pipes directly to the pumpjack's outlet port to transport oil to refineries or storage tanks. Optimal placement involves clustering pumpjacks on high-density oil patches to maximize flow rates while minimizing pipe length. Since they do not consume power, they can be placed anywhere within an oil field regardless of electrical grid proximity. Ensure that pipes are laid efficiently to avoid bottlenecks, as the raw output can quickly overwhelm small refineries if not balanced with sufficient processing capacity.
Did You Know?
- Pumpjacks do not consume any electricity; they run entirely on the pressure of the oil reservoir itself.
- The rate at which a Pumpjack extracts oil varies depending on how dense the specific oil patch is beneath it.
- In the early game, Pumpjacks are often the first machines players build that require fluid logistics management via pipes.
- Unlike other extractors, Pumpjacks cannot be moved once placed; they must be dismantled and rebuilt to relocate.
Frequently Asked Questions
What is the primary function of a Pumpjack?
The Pumpjack's main role is extracting crude oil from underground reservoirs directly beneath it. It operates passively, meaning it does not consume electricity while drawing fluids to the surface.
Where can I place a Pumpjack on the map?
Placement is strictly limited to areas marked as underground oil fields visible on your terrain. Attempting to build one elsewhere will fail because there is no resource to extract.
Does the Pumpjack require power to run?
Unlike most factory machinery, this unit requires zero power consumption to operate its mechanical arm. Its activity depends solely on the density of the oil patch rather than energy supply.
How do I move the oil from a Pumpjack?
Extracted fluid must be moved away using a network of pipes connected directly to the machine's output port. Without piping, the accumulated oil will block further extraction.
Why is this machine essential for advanced production?
It serves as the critical entry point for all petrochemical processing chains within your industrial complex. Without this resource, you cannot produce solid fuel, lubricant, or plastic bars.
