335216 Mechanical Seal (SVCV)

Introducing the 335216 Mechanical Seal (SVCV) by Blackmer!

The 335216 Mechanical Seal (SVCV) by Blackmer is a high-quality pump component designed specifically for positive displacement and sliding vane pumps. This mechanical seal features a rugged construction with stainless steel faces and elastomeric sealing elements, ensuring durability and resistance to wear and chemical exposure, making it suitable for demanding industrial applications. 

Constructed with precision-machined stainless steel components and durable elastomers, the 335216 Mechanical Seal offers reliable sealing performance across a temperature range of -20°C to 150°C (-4°F to 302°F). Its design incorporates a force-energized, balanced sealing face configuration that minimizes leakage and extends service life in continuous operation.

Dimensions include a seal face diameter of 50 mm (2 inches), a shaft size compatibility of 25 mm (1 inch), and an overall seal outer diameter of 75 mm (3 inches). The seal assembly weighs approximately 0.3 kg (0.66 lb). Its compact dimensions make it compatible with Blackmer pump models that accommodate this size specification. The seal features a single hydraulic-acting face and a static secondary seal for enhanced reliability.

Key features include a stainless steel seal face for corrosion resistance, elastomeric primary sealing element for chemical compatibility, a spring-loaded, balanced design for reduced wear, and a temperature tolerance of -20°C to 150°C. It is suitable for use with a variety of fluids, including chemicals, oils, and water-based solutions, and can handle pressures up to 10 bar (145 psi).

Primarily, the 335216 Mechanical Seal is ideal for industrial process pumps, chemical handling systems, and water treatment facilities. It is suitable for applications where reliable sealing is critical for maintaining operational efficiency, especially within fluid transfer systems that demand long service life without frequent maintenance. Its robust design makes it an excellent choice for budget-conscious facilities seeking durability and high performance without replacing entire pump units.

The product ships as an assembled mechanical seal unit, including the seal faces, spring, elastomers, and installation hardware. Notably, it does not include pump-specific mounting adapters or replacement parts, which are sold separately.

Care instructions recommend regular inspection for signs of wear or leakage, with replacement intervals dictated by application conditions. The seal can be cleaned with compatible solvents and should be stored in a dry, clean environment. For warranty and detailed maintenance guidance, refer to Blackmer's official product documentation.
