APV SiC Tungsten Cobalt Chemical Mechanical Seal 25mm 35mm for Industrial Pumps and Wastewater Systems

The APV Mechanical Seal is a single seal, unbalanced design featuring loop transferring spring drive with forced direction of rotation. Engineered for chemical processing, refining, and wastewater applications, it offers reliable sealing performance in aggressive media environments.

• Spring unit averted from product flow to prevent sticking and clogging
• Safe operation with seal face locking by square pin to prevent fractures
• Suitable for pressure reversals and vacuum operation without additional seat locking
• No shaft damage from dynamically loaded O-Ring
• Compact installation sizes for space-constrained applications
• Ideal for conversions without pump adaptations
• Resistant to solid-containing and abrasive media
• Stationary design insensitive to shaft movements

• Water and wastewater treatment systems
• Chemical processing industry
• Refining technology applications
• Handling dirty, abrasive, and solid-containing media
• Processing sticky and stringy media
• Chemical standard pumps and sewage pumps

The silicon carbide (SiC) component provides exceptional hardness, superior wear resistance, and excellent chemical stability against corrosive substances. The tungsten-cobalt material ensures structural durability and maintains seal integrity under high-pressure conditions and extreme operating environments.

This seal is designed as an OEM equivalent to APV mechanical seals and can directly replace original equipment seals. Multiple material and end combinations are available to meet diverse industrial requirements.
