337017 Mechanical Seal (LVCV)

Introducing the 337017 Mechanical Seal (LVCV) by Blackmer

The 337017 Mechanical Seal is a precision shaft sealing component designed specifically for Blackmer positive displacement and sliding vane pumps. Manufactured with high-quality materials to ensure durability and reliable performance, this seal effectively prevents leakage and maintains pressure integrity during pump operation.

Constructed from corrosion-resistant metals and elastomers suitable for demanding chemical and fluid handling environments, the 337017 Mechanical Seal features balanced seal faces for reduced wear and longer service life. Its configuration provides a robust barrier against product loss and external contaminants, supporting continuous, leak-free operation. 

Dimensions include a standard seal face diameter compatible with specific Blackmer pump models, with dimensions typically around 2.5 inches (63.5 mm) in face diameter, and an overall seal height of approximately 4 inches (101.6 mm). The seal housing is designed to fit standard pump shafts, with an internal diameter tailored to the compatible shaft size, generally 1.5 inches (38.1 mm).

Key features of the 337017 Mechanical Seal include: high-performance elastomeric components resistant to chemicals and thermal cycling; metal parts crafted from stainless steel or other corrosion-resistant alloys; balanced face design reducing operational wear; integration with pump models requiring a 337017 seal; and ease of installation and maintenance. This seal withstands operating temperatures ranging from -20°C to +120°C (-4°F to +248°F) and handling pressures up to 150 psi (10 bar).

This product is ideal for use cases including fluid transfer in chemical processing, wastewater management, oil and gas industries, and other applications requiring durable and reliable pump sealing solutions. It is especially suited for operators seeking a long-lasting, maintenance-efficient seal that minimizes downtime. The 337017 Mechanical Seal is recommended for planned rebuilds and routine maintenance to restore sealing performance to like-new condition, making it a cost-effective choice for maintaining pump efficiency and reducing leak-related issues.

The package includes the 337017 Mechanical Seal assembly, with no additional components, gaskets, or mounting hardware included. Proper installation requires following manufacturer guidelines, and routine inspections are advised to ensure optimal performance.

Care instructions involve regular cleaning of seal faces with manufacturer-approved solutions, avoiding aggressive abrasives, and inspecting elastomeric components for wear or degradation. The seal is covered by a standard warranty provided by Blackmer, with specific terms depending on the supplier's policies.
