When a pump suffers from cavitation, is a pump lined with PTFE more durable, or one made of stainless steel 316?

Dear all: As the title suggests, when cavitation occurs in a pump, is one that has a PTFE lining more durable, or one made of stainless steel 316? Also, if a centrifugal pump has to run idle, what type of mechanical seal can withstand that? It’s about 3 minutes each time. Thank you

Any mechanical seal cannot withstand idling, let alone for 3 minutes. A packing seal might be able to hold up, but it causes significant damage to the shaft.
