DIRECTION OF ROTATION
The Revolution-series mechanical seals are independent of the direction of rotation.
TEMPERATURE LIMITS
Following temperature limits apply to the different seal faces commonly used within
mechanical seals:
Seal face max operating temperature, dependent on liquid being processed
Solid Resin-impregnated Carbon 200°C
Inserted Carbon 150°C
Solid Silicon Carbide 250°C
VISCOSITY LIMITS
Following viscosity limits apply to the different seal faces commonly used within
mechanical seals:
Seal face Viscosity [ cP ]
Solid Carbon Up to 5000
Silicon Carbide Up to 150000
For viscosities above 150000 cP double seals should be considered.
Note: For flush piping locations see 3.8.3
