 | Overview
This procedure is to be referenced during the inspections of the mixer’s male and female bearings.
When the mixer and bearing operate under suitable conditions many years of reliable operation can be expected. However, damage to the bearing can result from a sudden impact, dropping, dry running of the mixer or mishandling. Due to the nature of the ceramic bearing it should be routinely inspected to ensure properly running equipment.
NovAseptic Mixers utilize sliding bearings between the mixing head and male bearing. These bearings are manufactured from Silicone Carbide (SiC) which is among the hardest substances known. Due to this hardness, it makes for an excellent long lasting bearing material for rotating equipment in wet environments.
The static male bearing is secured to the vessel’s tank plate and the rotating female bearing is integrated and sealed into the mixing head, or rotor, of the mixer. These two components rub against each other as the mixing head rotates. Process fluid lubricates the bearings during operation. The service life of the bearings depends upon several factors:
- How the mixer is used and operates
- Condition of the process fluid
- Handling of the mixer when not in operation
