Fully interchangeable with original SOOSAN SP3-H diaphragm rock drill spare parts, consistent with OEM part numbers SOOSAN-SP3-H and 160100079. No cutting, grinding or modification needed for direct on-site installation.
Core wearing parts such as main diaphragm and leather cups adopt high-toughness FKM fluororubber with reinforced fiber layer, matched with PU anti-extrusion rings. Excellent oil corrosion resistance, anti-aging and anti-fatigue performance, stable operation under -25°C to 120°C wide temperature range, resistant to high-frequency impact fatigue cracking.
All components pass strict 16MPa high-pressure nitrogen sealing test. Effectively stop internal hydraulic leakage and external nitrogen loss, guarantee constant impact frequency (50Hz/3000bpm) and stable drilling power, avoid frequent pressure compensation shutdowns.
Covers all sealing and diaphragm consumables required for full disassembly maintenance of SP3-H rock drill. Integrated complete spare parts reduce repeated part procurement, shorten equipment downtime and lower overall mining operation maintenance cost.
Each seal kit undergoes air tightness, high-pressure impact and long-term aging fatigue tests before delivery, fully meets SOOSAN original factory quality standards, ensures long-term reliable operation under harsh underground rock drilling working conditions.
Suitable for all engineering equipment equipped with SOOSAN SP3-H hydraulic diaphragm rock drills: • Underground mine tunneling drilling rigs • Roadway bolter jumbos • Hydraulic rock drilling carts • Small tunnel boring auxiliary drilling equipment • Open-pit rock anchoring drilling machines • High-frequency impact hydraulic rock drilling systems • Heavy-duty mobile mining drilling machinery
Welcome to HOVOO, a Chinese seal factory. Production of PU, Rubber and PTFE seals. The seals include O-ring, piston seal, rod seal, Gray ring and gas seal.
