in addition to the butter packing and graphite packing, and that kind of durability?Butter and graphite packing is not durable, 35 days is gone, looking for a durable alternative filler, can be used for 32 weeks is OK
It doesn't seem to be, or you use a muddy filling!! But for your consideration, you have to have graphite packing or butter packing!! Butter packing is better than graphite packing!!!
Pump packing sealing pad a lot, but the best is aramid fiber, sealing performance is good, and the service life is very long, but the price is relatively high
