Mechanical seal MCM P/N PM25MS/TT Mission P/N 22451

The mechanical seals are made of high-quality Tungsten Carbide. Tungsten Carbide has proven itself as a highly abrasion-resistant material with a Ph range of 7 to 14.
For application with a lower Ph level the silicon Carbide vs. Silicon Carbide mechanical seal is recommended with its Ph range from 0-14.
Both mechanical seals are lubricated by the fluid being transferred and require the pump to remain premed during operation.
Custom mechanical seal options can be provided for specific applications.
