337201 Mechanical Seal (SVLV)

Introducing the 337201 Mechanical Seal (SVLV) by Blackmer

The 337201 Mechanical Seal is designed for use in Blackmer positive displacement and sliding vane pumps, providing a reliable shaft sealing solution for demanding industrial applications. Constructed from high-quality materials to ensure durability, this seal effectively prevents leakage under various operating conditions, including high pressure, thermal cycling, and wear exposure.

Materials used in the 337201 Mechanical Seal include carbon and elastomer components for sealing surfaces, combined with metal casings for structural integrity. This composition enhances the seal’s resistance to corrosion, thermal fluctuations, and mechanical stresses. The seal features a molded elastomer secondary seal and a ceramic or carbon primary sealing component, maximizing sealing performance and longevity.

Dimensions and compatibility details include a size tailored for specific Blackmer pump models, with a bore diameter appropriate to the pump shaft size—typically around ¾ inch (19 mm) or as specified in technical documentation. The seal assembly weighs approximately 0.2 kg, fitting seamlessly within the designated pump interface without requiring extensive modifications.

Key features of the 337201 Mechanical Seal include:

• Designed specifically for Blackmer pump models featuring SVLV configurations
• Primary sealing component available in ceramic or carbon for high wear resistance
• Elastomer secondary seal for enhanced chemical compatibility and sealing integrity
• Compact dimensions allowing easy installation and replacement
• Resistant to thermal cycling, pressure fluctuations, and aggressive fluids
• Reliable sealing at shaft speeds up to 3000 RPM

Its primary use cases involve sealing liquids in chemical processing, oil and gas, and water treatment applications where leak-proof operation and durability are critical. The 337201 Mechanical Seal is ideal for technicians seeking a budget-conscious, dependable replacement part to extend pump service life or upgrade existing sealing solutions, especially in environments where maintaining pressure integrity is essential.

Included with the 337201 Mechanical Seal are the seal assembly components, with potential replacement O-rings and gland plates sold separately. The product does not include mounting hardware or installation tools, which are typically supplied by the pump manufacturer or maintenance team.

Care instructions involve regular inspection for wear or damage, cleaning with compatible chemical solutions, and replacement of elastomer parts as needed. The seal can be maintained by following manufacturer-specific guidelines, and warranties typically cover defects in materials or workmanship for up to one year from purchase.
