Can bearing protectors operate without medium lubrication?
Thread Content
During operation, with no medium for lubrication, will it overheat? During shutdown, with medium lubrication, is sealing required? Is it possible?
What is a bearing protector? Are there any pictures?

I just picked any website randomly; I used INPRO before, but it was too expensive. Now, domestic products are also of good quality. It seems that in China, this product isn’t being utilized to its full potential
This must be the shaft seal of the pump, with sealing surfaces for the stationary and rotating rings. The INPRO/SEAL bearing isolator is a non-contact labyrinth-type oil seal that prevents the entry of water and air. It consists of a rotor and a stator, and it is similar to magnetic oil seals. It is used in pumps that are lubricated by oil mist; it also has moving and stationary rings, and the sealing surfaces are lubricated by oil and gas during operation, which prevents damage.
Will it get damaged if only gas passes through the sealing surface? I’ve always had doubts about this
No. A little oil will seep to the end face when it’s in operation. It won’t grind dry
Will it get damaged if it’s just dry grinding?
