Bellows Cartridge Seals

Bellows Cartridge Seals

Bellows cartridge seals are factory preset mechanical sealing units designed for pumps, mixers, agitators and rotating equipment where simplified installation, reliable leakage control and dependable sealing performance are required.

By combining cartridge seal construction with a bellows-driven sealing element, these seals help maintain controlled face movement while reducing installation error and maintenance time. They are commonly selected for chemical, corrosive and demanding industrial duties where metal bellows construction, factory preset assembly and stable sealing performance are important.

Bellows cartridge seals are commonly used in:

• chemical process pumps
• water treatment pumps
• industrial mixers
• agitators
• rotating process equipment
• corrosive and demanding industrial applications

Depending on duty, they may be configured as:

• single bellows cartridge seals
• double bellows cartridge seals
• quench, flush or drain variants
• application-specific metal bellows cartridge seal systems

These seals are often chosen where maintenance teams need:

• factory preset installation
• reduced seal setting error
• dependable face tracking
• stable performance in corrosive service
• reliable leakage control in continuous-duty rotating equipment

To specify the correct bellows cartridge seal, provide:

• shaft size
• seal chamber or housing dimensions
• equipment type
• fluid handled
• operating pressure and temperature
• speed and duty conditions
• single or double seal requirement
• existing seal sample or drawing if replacing

Kaybin supports replacement bellows cartridge seals, reverse engineering from existing units and seal selection for pumps and rotating equipment across South Africa and Africa.
