3115247200 Atlas Copco Diaphragm 3115 2472 00 Epiroc Drill Rig cop1838 cop 1840 2238 membrane part

The diaphragm your Epiroc COP rig actually needs — straight from Atlas Copco, no surprises.

This is the Atlas Copco 3115247200 diaphragm — same as 3115 2472 00 — built for Epiroc COP 1838HD, COP 1840, and COP 2238 rock drills. It sits inside the pneumatic or hydraulic circuit handling pressure separation and control. When it gets tired, response slows down and inconsistency creeps in. Swapping in a genuine part avoids guesswork on dimensions, material behavior, and fit. No extra trimming, no second-guessing torque specs. Just pull the old one, drop this in, and get back to drilling.

Highlights
Key Advantages
  • Part number 3115247200 (also listed as 3115 2472 00) — matches factory drawings exactly, no adapter plates needed.
  • Handles pressure cycling in hammer and feed circuits without ballooning or cracking early, even on multi-shift sites.
  • Drop-in for COP 1838HD, COP 1840, COP 2238 — same diaphragm used across these Epiroc models simplifies your spare parts shelf.
  • Material follows Atlas Copco's compound spec, so it keeps its flexibility after months of exposure to mineral oil and temperature swings.
  • Routine replacement here keeps drill impact energy steady and reduces unplanned downtime caused by sluggish control response.
Use Cases
Applications
  • COP 1838HD — pressure regulation in percussion circuit
  • COP 1840 — membrane separation in hammer control module
  • COP 2238 — pneumatic/hydraulic interface in feed and rotation control
  • Any Epiroc surface or underground drill rig using this diaphragm reference
  • Fleet maintenance where multiple COP models share the same diaphragm stock code
  • Replacing a hardened or swollen original membrane that no longer seals properly

FAQ
FAQ
How do I know this diaphragm fits my COP rig?
If your current diaphragm has 3115247200 or 3115 2472 00 stamped or printed on it, this is the direct replacement. It covers COP 1838HD, COP 1840, and COP 2238. Still unsure? Send us your machine’s model and serial — we’ll cross-check before shipping.
Is it actually an Atlas Copco part, or an aftermarket copy?
It’s factory-packed Atlas Copco OEM. Not a generic alternative. Same compound, same dimensions, same behavior under load as what came in the rig from day one.
What’s the usual lead time?
If your part number is in our warehouse, it leaves within 24 to 48 hours. Transit time is usually 3 to 7 business days depending on where you’re located. We’ll give you a firm timeline once you confirm the shipping address.
Can I replace it myself, or do I need a service tech?
Most crews swap these during routine hammer or valve service. It’s a straightforward remove-and-replace job if you have basic hand tools and follow the pressure relief steps in the manual. If you need pointers, reach out — we can walk you through the torque and alignment details.
What if it fails early?
Genuine Atlas Copco parts come with standard manufacturer warranty against material or workmanship defects. Save your installation record and we’ll handle any claim. In practice, failures are rare unless the system has contamination or pressure spikes beyond spec.
