Features and Benefits
- Self-lubricating carbon or filled PTFE seal face runs completely dry without cooling. Long life and reliability are achieved in the dry vapor space at the top of the mixer vessel while eliminating product contamination from liquid barrier fluids.
- Flexible rotor design compensates for shaft misalignment. Clearances, drive design, seal face dimensions, and o-ring configuration were optimized for the high run-out requirements of mixers and similar equipment. The VRA operates at eccentric run-out levels up to 3.81 mm (0.150 inch) TIR.
- Double o-ring mounted stator prevents distortion. Various configurations are available to fit different equipment types.
- Non-metallic collar option provides superior chemical resistance. Designated the VRA-C, a two-piece collar design eliminates the need for expensive exotic metal alloys in non-wetted areas.
- Optional sanitary gland allows steam cleaning and sterilizing of the seals interior while mounted on the equipment. Sanitary porting aids in the removal of steam cleaning debris.
