Key Features

• Axial Flexibility: Rubber components compensate for shaft runout and misalignment.

• Double Seal Barrier: Zero emissions option for toxic or hazardous fluids.

• Non-Pusher Protection: The bellows in both the single and double mechanical seal grip the shaft, protecting it from fretting wear and eliminating the need for dynamic O-rings.

• Modular Convertibility: Easy switch between single/double configurations using common parts.

• Optimized Rubber Formulation: High-grade NBR/EPDM/FKM compounds are used in the construction of both the single and double mechanical seal, ensuring long service life and chemical resistance.

FAQs About Single and Double Rubber Cartridge Mechanical Seal

Q: When should I choose the Double seal arrangement over Single?

A: You should choose a Double seal if the media is toxic, flammable, hazardous, contains high concentrations of abrasives, or is prone to crystallizing (like sugar syrup or glue). The double arrangement provides a safety buffer fluid that lubricates the faces and prevents process media from leaking into the atmosphere.
