Description

The 331604 Mechanical Seal (INBN) by Blackmer is a high-performance, leak-free sealing solution designed for positive displacement and sliding vane pumps.

This mechanical seal features a durable construction using materials such as carbon-related face material, ceramic or silicon carbide for the stationary and rotating faces, and stainless steel components for corrosion resistance and long-term reliability. The seal's design ensures a tight, dependable fit for compatible pump models, aiding in the prevention of fluid leakage and contamination.

Dimensions and specifications include a shaft size range of approximately 1.5 inches (38 mm) with a seal face diameter of around 2.2 inches (56 mm). The seal assembly weight is approximately 1.2 kilograms. It is suitable for operation in fluid temperatures up to 250°F (121°C) and pressures up to 150 psi (10.3 bar). 

Key features of the 331604 Mechanical Seal include a simple installation process with compatible pump models, a corrosion-resistant design made from stainless steel and composite materials, a dual-face sealing system with precisely machined faces for minimal leakage, and a compact construction that fits standard pump configurations. The seal is designed for continuous duty, supporting optimal pump performance in demanding environments, including chemical processing, water treatment, and fluid transfer systems.

This mechanical seal is ideal for users seeking to prevent product loss, protect pump bearings, and maintain reliable operation over extended service intervals, all within a budget-sensitive setup, since it is compatible with many standard pump models and replacement needs.

Included in the box are the 331604 Mechanical Seal assembly and installation manual. Not included are pump-specific components like shafts, sleeves, O-rings, or gaskets, which should be inspected and replaced as necessary during installation.

Care instructions involve regularly inspecting the seal for wear, cleaning with compatible solvents, and replacing worn parts promptly. The seal's stainless steel components support corrosion resistance, while its design facilitates ease of maintenance. Warranty details depend on specific suppliers and installation conditions.
