Can’t find Mini Pumps in ARC Raiders? Find them faster, spend less time fighting RNG, and secure the upgrade materials you need without wasting another raid.
Look, Raiders, we’ve all been there. You survive a rough raid, dodge a pack of ARC machines, sweep three different POIs, and finally hit the extract with a backpack full of scrap. Then you get back to your Outpost and realize you still haven’t found a single Mini Pump.
Yeah, the grind is real.
The Frozen Trail update introduced Mini Pumps to ARC Raiders, and if you’re trying to upgrade your Research Station, tracking down these little pieces of hardware can turn into a supply run you never wanted to take.
The trick is knowing where to look instead of wasting an entire raid looting every random container you stumble across.
Your best starting point is Pendola Pass, particularly the Cielo Sereno Observatory and the industrial areas around Seed Vaults. You can also check Stella Montis, the Space Travel building in Buried City, and Technological or Electrical loot zones on other maps.
Here’s the field intel you need to plan your route, secure the hardware, and make it back to the Outpost in one piece.
Loadout Tip: Mini Pumps are Uncommon recyclable items. Each weighs 0.5 kg, and you can stack up to five per inventory slot. Leave enough room in your backpack for the loot you actually came topside to collect.
Why Are Mini Pumps So Hard to Find in ARC Raiders?
Mini Pumps might not look like much, but they’re easy to overlook when you’re rushing through a building with ARC patrols nearby and rival Raiders somewhere in the same sector.
The bigger problem is loot RNG. A promising location doesn’t guarantee you’ll find a Mini Pump in the first container you open. You might spot one sitting on a table, find another inside a container, or leave the POI empty-handed because another Raider already swept through it.
Mini Pumps are classified as Uncommon recyclable items associated with Technological and Electrical loot. That gives us a starting point for choosing locations instead of searching blindly.
If you’re collecting them for the Research Station Level 1 upgrade, current upgrade guides list three Mini Pumps as the requirement. Check your own upgrade panel before deploying so you know exactly how many you still need.
Important: Before heading topside, check the requirements in your Research Station upgrade panel. If you only need one more Mini Pump, there’s no reason to keep risking your best gear just to collect extras.
There’s also a useful backup plan: Mini Pumps can be recycled into one Sensor and two Plastic Parts. Still, don’t dismantle the pumps you need for your upgrade just because your inventory is getting crowded.
Recycling Tip: Keep the Mini Pumps required for your upgrade first. Recycle only the extras you can afford to lose from your stash.
Best Places to Find Mini Pumps in ARC Raiders
Not every Raider is going to have the same luck, so treat these locations as a priority list rather than a guaranteed farming route.
1. Pendola Pass — Cielo Sereno Observatory
Start here if you want a targeted Mini Pump run.
The Cielo Sereno Observatory is one of the locations worth checking on Pendola Pass. It’s a research-focused facility with technological loot areas to investigate, making it a sensible first stop when you’re hunting for hardware.
Once you reach the Observatory, don’t just sprint straight through the main entrance and leave.
Here’s how to sweep it:
- Move through the research and terminal areas.
- Check desks, equipment surfaces, shelves, and nearby containers.
- Search utility boxes and other lootable storage as you work through the facility.
- Check accessible side rooms before moving to the next section.
- Keep an eye on your surroundings while looting. Getting caught in a fight with your backpack open is a great way to donate your supplies to someone else.
Mini Pumps have been reported around the Observatory, but the exact spawn isn’t guaranteed. If another squad has already cleared the building, don’t waste the rest of your raid searching empty rooms.
Raider’s Tip: Make a quick, systematic sweep of the Observatory. Search each accessible room once, collect useful loot, and move on if the area has already been picked clean. Don’t let one POI eat your entire raid.
2. Pendola Pass — Industrial Areas Around Seed Vaults
Need another place to check after the Observatory? Head toward the industrial area around Seed Vaults.
Players have reported finding Mini Pumps in this sector, making it a useful alternative when the Observatory doesn’t deliver.
Focus on accessible industrial spaces and inspect the loot rather than opening every container automatically. Check shelves, tables, carts, and containers you can safely reach.
The idea is simple: sweep the area thoroughly without turning a targeted loot run into a full-map sightseeing tour.
Keep your route flexible. If you hear gunfire nearby or spot signs that another squad is working the same POI, decide whether the remaining loot is worth the risk.
You came for Mini Pumps, not a long firefight over an empty locker.
Field Intel: If the Observatory is empty, switch to another promising loot area rather than repeatedly searching the same rooms. A backup POI is part of your route, not an afterthought.
3. Buried City — Space Travel Building
Pendola Pass isn’t your only option. If you prefer searching an established map, put the Space Travel building in Buried City on your list.
Player reports point to two specific areas inside the building:
- Top floor: Check the area behind the barricaded doors.
- Second floor: Search the floor reached by dropping down using the drop-mantle trick.
These are useful directions because they narrow your search to particular floors instead of sending you through the entire building.
Approach carefully, check your access route, and don’t assume the Mini Pump will be sitting in the same spot every time. Search the available loot and move on if the area has already been cleared.
Route Tip: Prioritize the top floor behind the barricaded doors and the accessible second-floor area. These are player-reported search spots, not guaranteed spawns, so keep an alternative destination in mind.
This is a good alternative when you want to change maps rather than repeatedly deploying to the same sector.
4. Stella Montis — Check the Indoor Areas
Still getting bad RNG? Stella Montis is worth a run, too.
Some players have reported finding Mini Pumps across the map, including in indoor locations. However, reports are mixed, so don’t assume Stella Montis is automatically the best option for every raid.
Focus on searchable indoor areas and look beyond the obvious containers.
Check:
- Tables and shelves
- Equipment surfaces
- Accessible storage containers
- Loading and cargo areas
Pay attention to loose loot sitting out in the open. It’s easy to overlook an item when you’re focused on opening lockers and cabinets.
If you find the area already looted, rotate rather than retracing the same empty rooms.
Looting Tip: Don’t just check lockers. Scan tables, shelves, and other accessible surfaces as you move between rooms. A quick visual sweep helps you avoid overlooking loose loot while keeping your route moving.
The goal is to secure the bag, not prove that one particular map has to work.
5. Other Locations Worth Checking
If your usual route keeps coming up empty, expand the search.
Players have also reported Mini Pumps at the Blue Gate fuel station and mechanical areas, as well as the research station in Buried City.
You can investigate the Port Authority building and Customs House on Riven Tides as additional technological-loot stops. Check their office and control-room areas, but don’t treat either location as a guaranteed Mini Pump spawn.
Before deploying, inspect the POI information on your map and prioritize areas associated with Technological or Electrical loot.
That doesn’t guarantee the item will appear, but it gives your supply run a clear direction.
Planning Tip: Pick your main POI and backup POI before deployment. If your first stop is looted or too dangerous, rotate to the alternative instead of wandering around the map without a plan.
How to Farm Mini Pumps Faster in ARC Raiders
Knowing a few locations is useful. Knowing how to approach them efficiently is what keeps the grind manageable.
Check Your Map Before Deploying
Before you lock in your deployment, inspect the map and the loot information available for each POI.
Look for areas associated with Technological or Electrical loot. Prioritize those over unrelated residential or medical locations when your primary objective is a Mini Pump.
Pendola Pass is a sensible starting point because it has several promising places to search. If the location you want is contested or its loot has already been collected, have an alternative ready.
Pre-Raid Checklist: Know your target POI, identify a backup location, leave enough inventory space, and make sure you have an extraction plan. The faster you can make decisions topside, the less time you waste fighting RNG.
Search Tables and Shelves, Not Just Containers
Don’t spend the whole raid opening lockers while ignoring everything sitting in plain sight.
Mini Pumps have been reported as loose loot on surfaces such as tables, shelves, and carts. Check these spots while moving through the facility rather than doubling back after you’ve already cleared the room.
A quick visual sweep can save time and keep you moving.
Keep Your Route Tight
A targeted loot run should have a beginning, a fallback, and an extraction plan.
Quick Supply-Run Strategy
- Deploy to Pendola Pass.
- Search Cielo Sereno Observatory.
- Check the industrial area around Seed Vaults if you need another stop.
- Collect other useful loot along the route without overloading your backpack.
- Extract when you’ve secured the Mini Pumps you need or the risk of continuing outweighs the reward.
You don’t need to clear an entire map. A focused route is easier to manage, especially when you’re running solo or using a loadout you don’t want to lose.
Don’t Turn a Loot Run Into an Unnecessary Fight
Mini Pumps are the objective. Every extra minute spent fighting over an already-looted POI is another chance to lose the supplies you’ve collected.
Watch for ARC patrols, listen for nearby combat, and keep track of your extraction options. If a location becomes too dangerous, reposition instead of forcing the fight.
There’s no shame in leaving with one Mini Pump rather than losing your entire kit while chasing a second.
Survival Tip: If you’ve secured the Mini Pump you came for and the area is becoming dangerous, consider extracting instead of pushing deeper. Another room might contain more loot, but it could also cost you everything you’re carrying.
What Should You Do With Mini Pumps?
Once you finally secure the hardware, don’t immediately dismantle everything you find.
If your Research Station upgrade requires Mini Pumps, keep the amount you need until you’ve completed the upgrade. Check the in-game requirements before deciding what to recycle.
Mini Pumps also have a use as recyclable materials. Recycling one yields:
- 1 Sensor
- 2 Plastic Parts
That makes spare Mini Pumps useful when you no longer need them for progression.
Inventory Tip: Separate your upgrade materials from your surplus loot mentally before recycling anything. Holding on to the required Mini Pumps saves you from running another raid just to replace what you dismantled.
The important thing is to avoid recycling an item that would force you into another raid to replace it.
Mini Pump Farming: Common Problems and Fixes
Why Can’t I Find Mini Pumps in ARC Raiders?
Mini Pumps are loot items, not guaranteed pickups at a fixed location. You can search a promising POI and still leave without finding one.
Prioritize Technological and Electrical loot areas, inspect loose items as well as containers, and change locations when your first choice has already been cleared.
Quick Fix: If you’ve searched the same POI without finding a Mini Pump, switch to your backup location. Repeating the same empty sweep won’t guarantee better RNG.
Are Mini Pumps Guaranteed to Spawn at Cielo Sereno Observatory?
No. The Observatory is a promising location reported by players, but a recommended farming spot isn’t the same as a guaranteed spawn.
Search the available loot and have a backup location ready.
Can I Find Mini Pumps Outside Pendola Pass?
Yes. Player reports also identify locations on Stella Montis and Buried City, including the Space Travel building. The Blue Gate fuel station and mechanical area have also been mentioned as alternatives.
Is a Mini Pump the Same as a Bicycle Pump?
No. They’re separate items. Make sure you’re searching for Mini Pump specifically rather than following a guide for Bicycle Pump locations.
Important: Double-check the exact item name before following a farming guide. Searching for the wrong pump can send you to the wrong POIs and waste an entire deployment.
Should I Recycle Extra Mini Pumps?
Only after accounting for your upgrade requirements. Once you’ve kept the amount you need, spare Mini Pumps can be recycled into Sensors and Plastic Parts.
Final Raider Intel
Finding Mini Pumps in ARC Raiders comes down to picking the right loot areas, searching efficiently, and knowing when to extract.
Start with Cielo Sereno Observatory on Pendola Pass, then check the industrial area around Seed Vaults. If those locations don’t deliver, try the Space Travel building in Buried City or search Stella Montis for loose loot and containers.
Remember, a promising location is not a guaranteed spawn. Keep your route flexible, watch your flanks, and don’t risk a full backpack just because one more room might contain the item you’re missing.
Final Raider Tip: Secure the Mini Pumps. Keep your upgrade materials. Hit the extract. The objective is to finish your supply run with the hardware you need—not to lose your entire kit chasing one more container.
We’ll see you back at the Outpost, Raider.
