About this product

Flowserve’s 682 Seal Cooler family uses “shell and tube” systems with optimized baffling that lowers the fluid temperature passing through the tubing while minimizing scaling and fouling of the water passing through the shell. Compatible with single or dual mechanical seals, 682 Seal Coolers are utilized as standalone units or part of a comprehensive piping plan package.

The 682M Seal Cooler is our mid-level option, ideal for operations that want to balance cost with ease of maintenance. Maintenance teams can disassemble the unit in the field for easy cleaning and inspection. The 682M Seal Cooler is available in series or parallel flow configurations.
