A preassembled, back-to-back double cartridge seal with an integrated, seal aligning roller bearing. Suitable for operation with a pressurised fluid. A double reverse pressure if there is a loss of barrier fluid pressure.

Designed using API 682 construction guidelines.

Features

• Double balanced design able to tolerate unexpected reverse pressure.
• High performance solid seal rings developed with FEA analysis to avoid deformation.
• Optional: sanitary gland to avoid product contamination and cooling jacket for high temperature applications.
• Retained stationary ring to prevent blow out during reverse pressure.
• Robust drive lugs that can tolerate run-out and vibration.
• Optional thermocouple for ATEX applications.
• Bearing protection ring to contain lubrication.
• Positioning device for easy, precise installation.
• Shrink disk drive to guarantee and maintain correct seal axial position under high process pressure conditions.
• Self aligning roller bearing to ensure minimum seal run-out.
• Atmosphere leakage monitoring connection.
• Flushing connections designed to ensure air is always vented.
