Description
Latest generation gas lubricated double seal developed to safeguard the environment and eliminate process contamination. The seal is designed with “Fluilift” non contacting face technology, and is pressurized with an inert gas that lubricates the faces and provides a gas barrier between process and atmosphere. The seal incorporates laser etched grooves that maintain a controlled gap between the faces, even at low rotating speeds, eliminating friction, heat generation and process contamination. Power consuption is also reduced. Equipped with ball or roller bearing to minimise seal run-out. Designed using API 682 construction guidelines.
- Seal rings designed using FEA to ensure correct flatness in all operating conditions.
- Retained stationary ring to prevent blow out during reverse pressure.
- Flange designed to guarantee correct stationary ring alignment.
- Optional: sanitary gland to avoid product contamination and cooling Jacket for high temperature applications.
- Connection for gas flushing.
- Multiple springs for uniform face loading.
- Bearing protection ring to contain lubrication.
- Positioning device for easy, precise installation.
- Self-aligning drive collar.
- Ball or roller bearing to ensure minimum seal run-out.
- Atmosphere leackage monitoring connection.
- Three robust drive lugs that can tolerate run-out and vibration.
