4. FAQ

Q: What modified elastomer raw material is adopted for the core rotary oil seals inside this transmission pump overhaul kit?
A: The primary rotary oil seals are made of magnolia leaf fiber modified HNBR compound. This kit is equipped with EPDM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the transmission pump assembly.

Q: What exterior characteristics help buyers quickly distinguish all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte jet black with delicate uniform grain; metal shells and tension springs have consistent silvery chromate galvanized surface; nylon backup rings are light ivory. All accessories are precision trimmed without burrs or warpage.

Q: What steady-load working conditions is this oil seal kit designed to adapt to on medium wheel loader transmission pumps?
A: This integrated kit combines rotary shaft lip seals and static flange sealing assemblies. It prevents transmission hydraulic medium leakage and blocks external contaminants from entering the pump during long-duration continuous equipment operation.

Q: What continuous working temperature range enables this whole sealing kit to sustain stable sealing capacity?
A: Its applicable temperature range covers -150°C to 446°C, suitable for cold mountain winter stockyard transportation and long-time gearbox auxiliary oil supply work in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on transmission pumps of all construction machinery?
A: It is dimensionally customized exclusively for medium wheel loader transmission pump structures only. It cannot match motor grader hydraulic assemblies, crawler excavator hydraulic motors or road roller drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.54MPa and 7.34MPa, and cope with pressure fluctuations generated during frequent gear shifting.

Q: What typical engineering projects require this transmission pump seal kit for regular maintenance?
A: It supports routine overhaul of transmission pump sealing assemblies on medium wheel loaders, widely applied in quarry aggregate distribution, port bulk cargo transfer, rural road upgrading and construction waste storage projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals circulating in the spare parts market?
A: Magnolia leaf fiber filler greatly improves compression recovery and hydrolysis aging resistance. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.10 times that of conventional nitrile oil seals.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
