This heavy-duty diaphragm & cup seal repair kit is customized for SOOSAN SP3-LOW low-pressure hydraulic rock drifters, widely adopted in underground mine tunneling, roadway drilling and rock bolting projects. It contains full set of accumulator diaphragm, rubber cup seals, O-rings, gaskets and PTFE backup rings for complete drifter overhaul.
Manufactured with imported high-performance HNBR and FKM fluororubber, the kit delivers outstanding hydraulic oil resistance, anti-fatigue and anti-aging performance under frequent high-frequency impact. It perfectly matches original SOOSAN spare parts, thoroughly solves common failures including accumulator air leakage, internal hydraulic oil seepage, unstable impact force and pressure attenuation, and greatly extends the service life of SP3-LOW rock drill under long-time continuous drilling operation.

Fully dimensionally consistent with original SOOSAN SP3-LOW rock drill sealing parts, matches OEM part numbers SOOSAN-SP3-LOW, C53222 and C51146. No cutting, grinding or modification needed for quick direct installation, perfectly fit accumulator and percussion cylinder assembly.
Core wearing parts (diaphragm and percussion cup seals) adopt high tensile HNBR and FKM fluororubber with fiber reinforcement layer. Excellent hydraulic oil corrosion resistance, fatigue crack resistance and high-low temperature stability, stable operation in -30°C to 120°C underground harsh environment.
All finished parts pass strict 16.0MPa hydraulic fatigue impact test. Effectively block accumulator nitrogen leakage and internal/external oil seepage, maintain stable percussion frequency and consistent drilling impact force, avoid power drop during long-hour rock drilling.
Covers all sealing rubber and gasket parts required for full machine maintenance of SP3-LOW drifter. One set meets full overhaul demand, reduces spare parts matching time and lowers mine equipment downtime & maintenance cost.
Each seal kit undergoes air tightness, high-pressure fatigue and thermal aging tests before delivery, fully meets SOOSAN OEM manufacturing standards, guarantees stable long-term performance under underground heavy-duty drilling conditions.
Designed exclusively for SOOSAN SP3-LOW low-pressure hydraulic rock drifters, widely used on below heavy-duty underground engineering equipment: • Underground mining tunneling drill jumbos • Coal mine roadway rock bolting rigs • Metal mine excavation drilling equipment • Tunnel small drilling rigs & bolting trolleys • Underground low-pressure hydraulic drilling transmission systems • Continuous impact mobile rock 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.
