Highlights
Key Advantages
- Fits Epiroc / Atlas Copco COP drills from the 1238K up through 2560+ and MD20—check your serial number or parts book for exact match.
- Made from a heat-cured elastomer bonded to steel. It handles the pressure spikes and flex cycles that kill cheaper compounds in a few shifts.
- Swapping it out takes a fraction of the time compared to sending a hammer out for rebuild. Most crews can handle it during a scheduled PM window.
- A blown diaphragm often causes cavitation damage downstream. Replacing it early keeps your pistons, valves, and seals out of trouble.
- We ship same-day out of multiple warehouses. If we don't have it on the shelf, ETA is an honest window, not a guess.
Use Cases
Applications
- Underground jumbos running COP 1838, 2238, 2560 and similar hammers—drifters, bolters, long-hole rigs.
- Surface bench drilling with COP-powered crawler rigs in quarry or construction work.
- In-house rebuild kits: stock these diaphragms so you're not waiting on parts when a hammer loses pressure mid-shift.
- Used by mining contractors who handle their own rock drill maintenance and need consistent spares availability.
- Aftermarket supply for dealers and service centers that keep fleets of COP rock drills running across multiple sites.

FAQ
FAQ
Are 3115182201 and 3115 1822 01 the same thing?
Same part, different label. 3115182201 is the typical parts system format; 3115 1822 01 is how Epiroc often prints it on the packaging. Both are interchangeable.
Can this diaphragm fit my COP 1838HD+?
Yes, it's listed for the full COP 1838 family including HD, HD+, HE+, MUX, and MUX+. Double-check the parts breakdown for your specific hammer serial number if you're unsure—accumulator layouts can shift between serial number breaks.
OEM or aftermarket?
If you need the Epiroc/Atlas Copco branded piece, mention it in the order notes and we'll quote accordingly. Otherwise we normally supply a heavy-duty equivalent that meets the same hardness and burst specs.
When will this ship?
Warehouse stock normally goes out within 1 business day. If it's a backorder, actual lead time averages 5–10 working days depending on origin. We'll give you a firm date before you commit.
What are the usual symptoms of a worn diaphragm?
Percussion gets weak or irregular, often accompanied by oil foaming or overheating. Sometimes you'll see oil weeping around the accumulator cap. If you catch it during a visual inspection or pressure test, swap it before it takes out other hammer components.
Do you handle bulk orders for mine sites?
Yes. Shoot us your expected annual burn rate for these diaphragms and we'll set up a stock program or volume pricing so you're not chasing spot buys.
