Pumpjack — Factorio Production Calculator
Pumpjack is crafted in the assembling machine in 5 seconds, producing 1 per craft from 5 × Steel plate, 10 × Iron gear wheel, 5 × Electronic circuit, 10 × Pipe. At 60 per minute you need 10 assembling machines, and the chain behind it draws on 2 raw resources: iron ore, copper ore.
Production chain for 60 Pumpjack / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 3,600 | 192 | Furnace |
| Copper cable | 900 | 7.5 | Assembling machine |
| Iron gear wheel | 600 | 10 | Assembling machine |
| Pipe | 600 | 10 | Assembling machine |
| Copper plate | 450 | 24 | Furnace |
| Steel plate | 300 | 80 | Furnace |
| Electronic circuit | 300 | 5 | Assembling machine |
| Pumpjack | 60 | 10 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 3,600 |
| Copper ore | 450 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Pumpjack recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 5 s | 1 | Steel plate × 5, Iron gear wheel × 10, Electronic circuit × 5, Pipe × 10 |
What the whole chain needs
60 pumpjacks per minute pulls in 7 intermediate products, and the whole tree comes to 339 machines across 2 machine types, fed by 2 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 3,600 per minute, which is 4 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses pumpjack
No base-game recipe consumes pumpjack — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What pumpjack is made from
- Steel plate — 5 per craft
- Iron gear wheel — 10 per craft
- Electronic circuit — 5 per craft
- Pipe — 10 per craft
FAQ
How many assembling machines do I need for 60 pumpjacks per minute?
10 assembling machines. One at standard speed produces 6 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does pumpjack take?
At 60/min the chain consumes 3,600 iron ore per minute, 450 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
