5. FAQ

Q: What unique reinforcing filler is added to the main sealing lip rubber to boost durability?

A: Magnesium-aluminum fiber is blended into modified NBR to cut thermal shrinkage and resist oil-induced deformation under frequent pump load shifts.

Q: What visual color features can users tell apart among all kit accessories?

A: Rubber sealing parts are semi-matte jet black with smooth texture, metal components are silver-gray, and nylon back-up rings present clean milky white.

Q: What overall structural form does this overhaul oil seal kit adopt for pump maintenance?

A: It is an all-in-one matched multi-component assembly rather than a single seal, integrating main sealing, dust blocking and pressure buffering functions.
Q: What temperature fluctuation range can this sealing assembly work steadily within?

A: It maintains reliable performance from -125°C to 345°C, fitting frigid northern mine winters and non-stop high-temperature tropical heavy-duty work.

Q: Can this sealing kit be used for various common construction machinery types?

A: It is exclusively engineered for ultra-large mining excavator main hydraulic pumps and cannot fit loaders, graders or small and medium digging equipment.

Q: What regular hydraulic pressure range can this seal set withstand consistently?

A: It holds steady against 3.8MPa to 5.5MPa routine pressure and eases sudden pressure spikes from system startup and shutdown.

Q: What typical job sites is this sealing kit mainly developed to serve?

A: It targets regular overhauls of large mining excavator pump shafts for open-pit mining, big earthmoving and long-running infrastructure projects.
