Mechanical seals are a factor that has a decisive effect on the cost-effectiveness of your operation. Because their wear determines the productivity of the entire system, whether it is a pump, agitator or compressor. What causes damage to the seal faces? One reason is dry running which is often unavoidable due to insufficient lubriion or when gas-lubried seal faces get in contact.
