4. FAQ

Q: What special modified raw material is adopted to produce the core rotary oil seals inside this charge pump overhaul kit?
A: The primary rotary oil seals are made of pine needle fiber modified HNBR compound. This kit is matched with NBR static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the main charge pump assembly.

Q: What intuitive appearance features help customers distinguish all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte dark black with uniform delicate texture; metal shells and tension springs have smooth silvery titanium passivated coating; nylon backup rings are light ivory. All components are neatly trimmed without burrs or warping.

Q: What continuous rotation working characteristics is this oil seal kit designed to adapt to on medium large wheel loader main charge pumps?
A: This integrated kit combines rotary shaft lip seals and static flange sealing pieces. It avoids charge hydraulic medium leakage and prevents external dust from entering the pump interior during long-duration continuous equipment operation.

Q: What continuous working temperature range enables this whole sealing kit to keep stable sealing performance?
A: Its applicable temperature range covers -158°C to 454°C, suitable for cold plateau winter stockyard loading and long-time auxiliary hydraulic supply work in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on charge pumps of all construction machinery?
A: It is dimensionally customized exclusively for medium large wheel loader main charge pump structures only. It cannot match motor grader hydraulic assemblies, crawler excavator swing 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 6.70MPa and 7.50MPa, and cope with pressure fluctuations generated during frequent equipment start and stop.

Q: What typical engineering projects require this main charge pump seal kit for regular maintenance?
A: It supports routine overhaul of main charge pump sealing assemblies on medium large wheel loaders, widely applied in quarry aggregate transportation, port bulk cargo stacking, municipal road construction and solid 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: Pine needle fiber filler greatly improves compression recovery and anti-wear performance. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.26 times that of conventional nitrile oil seals.

Q: What typical engineering projects require this steering cylinder seal kit for periodic maintenance?
A: It supports routine overhaul of steering cylinder sealing assemblies on medium large wheel loaders, widely applied in aggregate storage yards, river dredging works, suburban road expansion and municipal solid waste disposal projects.

Q: How does the service lifespan of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals available on the spare parts market?
A: Oak leaf fiber filler significantly improves compression set resistance and anti-medium aging performance. Under long-cycle reciprocating friction working conditions, its service life reaches more than 3.28 times that of conventional nitrile oil seals.

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 6.76MPa and 7.56MPa, and withstand pressure surges generated during sudden heavy material lifting.

Q: What typical construction scenarios require this lift cylinder seal kit for regular overhaul?
A: It supports routine maintenance of lift cylinder sealing assemblies on large wheel loaders, widely applied in aggregate stockyards, open mineral loading, rural road upgrading and construction waste centralized disposal projects.

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: Camellia twig fiber filler significantly improves compression set resistance and anti-oxidation aging performance. Under long-cycle reciprocating friction working conditions, its service life reaches more than 3.32 times that of conventional nitrile oil seals.

Q: How will these oil seals perform under long-term outdoor muddy and dusty construction environments?
A: The precision sealing lip can scrape fine particles adhered to the piston rod surface. The metal outer shell isolates coarse grit, reducing abrasive wear and delaying the occurrence of slow hydraulic oil seepage.
