Productum Overview
This heavy-duty accumulator diaphragma peculiariter est constructus pro Epiroc 1238K hydraulic rock drill. It serves as the core rubber separating component for nitrogen accumulator, isolating hydraulic oil and nitrogen gas. Made of high-grade reinforced FKM fluororubber and fabric-reinforced rubber compound, this diaphragm delivers outstanding oil resistance, anti-fatigue performance and pressure-bearing capacity. It perfectly replaces original Epiroc diaphragm parts, resolves typical faults such as weak impact force, nitrogen leakage and unstable drilling power, and extends rock drill service life under continuous underground heavy-load working conditions.

Claves Venditionis Puncta
1. 100% Exact OEM Replacement. Fully compatible with original Epiroc 1238K rock drill. Matches OEM part number 3115182201. No modification required for direct field installation.
2. Premium Reinforced Diaphragm Material. Adopts fabric-reinforced FKM rubber structure. Excellent oil-proof, anti-aging and flex-fatigue resistance, maintaining stable performance under -25°C to 110°C cyclic pressure impact.
3. Zero Gas-oil Mixing & High Pressure Durability. Every diaphragm is strictly pressure-cycling tested under 28 MPa working pressure. Effectively prevents nitrogen leakage and oil-gas mixing, stabilizes accumulator energy storage and keeps consistent rock drill impact output.
4. Complete Matching Repair Accessory. Set includes main diaphragm together with matched O-rings for accumulator service. Complete supporting parts shorten on-site maintenance time and lower underground equipment operating cost.
5. Strictus Controlus Qualitatis Fabricae. Unumquodque diafragmata transit testus cyclorum fatigationis, hermeticitatis aeris, et resistentiae pressionis antequam ad munus mittatur. Ad normam OEM performance conformatur ut operationem subterraneam longi temporis fidam garantiret.
6. Campus Applicationis. Aptus est pro perforatore petreo Epiroc 1238K, qui in variis machinis perforationis subterraneis gravioribus montatur:
• Machinae perforatoriae subterraneae pro effodiendo tunicis
• Jumbos pro effodiendo in metalliferis
• Portantes perforationis petrae subterraneae
• Unitates hydraulicae perforatoriae
• Machinae effodientes subterraneae
• Apparatus perforatorius pro ancoris petreis
• Machinae perforatoriae mobilis subterraneae gravioris
