Atlas Copco 3115212100 Flushing Head / Water Swivel for COP 1838/1842 Drifter | Centralizer Adapter

High-Pressure Flushing and Centralizing Interface for Rock Drilling

Genuine Atlas Copco Flushing Head (Part# 3115212100), also known as a Water Swivel or Centralizer Adapter. This critical component serves two primary functions on COP 1838/1842 series drifters: it delivers high-pressure water or air for hole flushing and provides stability to the drill string. It is the essential link between the rotation unit and the drill rods.

Technical Specifications & Features:

• ⚙️ Compatible Drifter Models: Atlas Copco COP 1838, COP 1840, COP 1842, COP 1842HE
• 🔧 Connection Type:
  • Drifter Side: Splined or keyed connection to the rotation unit.
  • Rod Side: Standard thread (e.g., R32, T38, T45) for drill rod connection.
• ⛓️ Material: High-tensile, abrasion-resistant alloy steel
• 🛡️ Pressure Rating: Designed for high-pressure flushing (exact rating depends on drifter model and pump capacity)
• 📏 Sealing System: Multiple robust seals (often including a mechanical face seal) to prevent flushing medium leakage under high pressure and rotation.
• 🧰 Manufacturing Standard: Precision machined to OEM specifications for perfect fit and balance.

Key Functions & Benefits:

Compatibility & Application:

• Primary Application: Atlas Copco COP 1838, 1840, 1842, and 1842HE series hydraulic drifters.
• Fits various drill rigs (jumbos) equipped with these drifters, such as Boomer L2D, D7, etc.
• Connects the rotation unit to the first drill rod (shank adapter or starter rod).

⚠️ Important Notice & Maintenance Tip:

The flushing head is a high-wear component due to its exposure to high pressure, rotation, and abrasive slurries. Regular inspection is crucial:

• Inspect Seals: Replace at the first sign of leakage to prevent damage to the internal bearings and splines.
• Check Threads: Worn or damaged threads can cause poor rod connection and thread stripping.
• Look for Cracks or Erosion: Especially in the flushing channels, caused by high-pressure water and abrasive particles.
• Use Clean Flushing Water: Dirty water with high silt content will drastically accelerate wear on seals and the internal body.

Failure of this component leads to loss of flushing pressure, poor hole cleaning, and potential damage to the rotation unit.
