Description

The 337760 Mechanical Seal (RNBN) by Blackmer is a high-performance pump sealing component designed to ensure reliable operation and leak prevention in various industrial applications.

This mechanical seal features a composite construction utilizing PTFE sealing faces and stainless steel components, providing broad chemical compatibility, durability, and corrosion resistance. The seal incorporates a flexible secondary seal to allow for shaft movement, reducing wear and minimizing leakage risk. It is suitable for pumps operating in temperature ranges from -20°C to 120°C (-4°F to 248°F) and can withstand pressure up to 150 psi (10.3 bar).

The 337760 Mechanical Seal measures approximately 2.25 inches (57 mm) in outer diameter and 0.75 inches (19 mm) in height, fitting specific Blackmer pump models. Its balanced face configuration ensures even sealing contact and minimal heat generation, contributing to extended service life. The seal provides a 360-degree sealing surface for optimal performance.

Key features include:

  • PTFE sealing faces offering high chemical resistance
  • Stainless steel components ensuring structural strength and corrosion resistance
  • Outer diameter approximately 2.25 inches (57 mm)
  • Height approximately 0.75 inches (19 mm)
  • Temperature tolerance from -20°C to 120°C (-4°F to 248°F)
  • Maximum operating pressure of 150 psi (10.3 bar)
  • Flexible secondary seal for accommodating shaft movement and reducing wear

This mechanical seal is ideal for applications in chemical processing, water treatment, food and beverage manufacturing, and industrial systems where pump reliability, leak prevention, and system longevity are critical. It is recommended for maintenance technicians, OEMs, and engineers seeking a dependable sealing solution with long service life and minimal maintenance requirements.

Included in the package is the 337760 Mechanical Seal along with detailed installation instructions. Mounting hardware and pump-specific components are not included. Proper installation involves ensuring alignment and following manufacturer guidelines to maximize seal performance.

Regular inspection for signs of wear, contamination, or leakage is advised. Cleaning should be performed with appropriate solvents compatible with PTFE materials.
