Fully dimensional consistent with original EVERDIGM DRILL-LOW rock drill sealing accessories, perfectly matching OEM part numbers ED-DRILL-LOW, AB168-0092 and D-13027601. No cutting, grinding or modification required for one-step direct installation, compatible with all standard DRILL-LOW drifter assemblies.
The core rubber cup diaphragm adopts textile-reinforced composite FKM material, resisting high-frequency impact fatigue and hydraulic oil swelling. Auxiliary sealing components use high-temperature resistant fluororubber with anti-aging formula, stable performance under -30°C ~ 120°C severe working environment, effectively resisting mineral hydraulic oil and emulsified drilling fluid corrosion.
All components pass 17MPa long-cycle impact fatigue testing. The thickened integrated diaphragm avoids premature cracking under continuous drilling impact; matched anti-extrusion backup rings eliminate seal extrusion deformation, stop internal and external hydraulic leakage, stabilize impact frequency and maintain consistent drilling power output of the rock drill.
Covers every sealing and diaphragm part required for full machine disassembly maintenance of DRILL-LOW drifter. Integrated complete accessories eliminate separate procurement of scattered spare parts, greatly shorten on-site repair downtime and reduce overall equipment operation & maintenance cost.
Each full set undergoes air tightness test, high-pressure impact fatigue test and thermal aging test before delivery, fully complies with EVERDIGM original factory quality standards, guarantees stable long-term operation under harsh mining & tunnel construction conditions.
Specially matched for EVERDIGM DRILL-LOW diaphragm rock drills installed on various heavy-duty drilling equipment: • Underground mining hydraulic drilling jumbos • Tunnel excavation single-arm & double-arm rock drill rigs • Small portable hydraulic rock drilling machines • Metallurgical mine roadway drilling equipment • Hydraulic diaphragm impact drilling systems • Underground engineering mobile drilling machinery
