4. FAQ

Q: What visual characteristics help buyers distinguish different sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are dark black with delicate matte surface; metal shells and tension springs have uniform silver anti-corrosion plating; nylon backup rings are light beige. All accessories have smooth edges without deformation or burrs.

Q: What heavy-load working conditions is this oil seal kit designed to adapt to on large wheel loader main hydraulic pumps?
A: This integrated kit combines dynamic shaft lip seals and static flange sealing pieces. It avoids internal hydraulic oil leakage and prevents external pollutants from invading the pump during frequent lifting and loading operations.

Q: What continuous working temperature range allows this whole sealing kit to maintain stable sealing performance?
A: Its applicable temperature range covers -173°C to 469°C, suitable for cold plateau winter open stockyard operation and long-duration heavy aggregate loading work in tropical mining yards.

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

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-term cyclic operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.98MPa and 7.78MPa, and cope with pressure fluctuations generated during frequent loading and unloading cycles.

Q: What typical engineering projects require this main hydraulic pump seal kit for regular maintenance?
A: It supports routine overhaul of main hydraulic pump sealing assemblies on large wheel loaders, widely applied in open-pit mineral stacking, port bulk cargo transfer, highway aggregate storage and construction waste treatment 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: 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.
