Key Features

• High-Temp Cartridge Standard: A direct replacement for the industry-standard "606" style high-temperature cartridge metal bellows mechanical seals used in refineries and petrochemical plants.

• Steam Quench Ready: Comes standard with quench and drain ports (API Plan 62) to manage leakage and prevent coking.

• Stationary Bellow Design: The bellow is stationary, which handles high speeds better than rotating bellows by avoiding centrifugal stress on the leaflets.

• Robust Drive Lugs: Features heavy-duty drive lugs to transmit torque reliably even when processing high-viscosity fluids like bitumen.

• Grafoil Secondary Seals: Uses die-formed flexible graphite rings exclusively, ensuring zero rubber content for maximum temperature capability.

FAQs about Type 606 cartridge metal bellows mechanical seal

Q: Why use a stationary bellow?

A: In rotating bellows, centrifugal force can distort the leaflets at high speeds. A stationary bellow remains static, allowing the seal to operate at much higher shaft speeds (up to 50 m/s) without fatigue.
