What is a mechanical seal?
A mechanical seal is a spare part that helps connect systems or mechanisms together by preventing leakage (e.g. in a pump), generating pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion of the sealants and compression of the gaskets. Normally, a mechanical seal includes rotating parts and stationary seal parts with secondary seal part like o-ring. Besides that, the material for secondary seal is usually rubber, like NBR, BUNA, EPDM or VITON (FKM).
How to choose the materials for mechanical seals?
There are some rules when choosing the materials for a mechanical seal. For example, we use ceramic as the material for stationary seals, carbon for the seal face, and NBR for the O-ring. Be careful when you use hard material for both rotary and stationary seal face. The temperature will be very high when mechanical seal runs, so make sure you have equipped cooling system for your mechanical seal. If not, the rubber parts of the mechanical seal will be get burnt soon.
How to choose the rubber part for a mechanical seal?
Different rubber working for different medium, NBR is a popular and cheap rubber material, normally working for clean water and not too high temperature, if working for some chemical medium, better choose epdm or viton, and if working for high temperature, then viton is a better material.
