A well-designed system is crucial for extending the lifespan of pump bearings and mechanical seals. For seals specifically, proper lubrication, cooling, and cleaning are essential. To support these functions, a high-temperature flushing fluid—either the process fluid itself or a separate barrier fluid—is routed to the seal cooler. In the cooler, heat is transferred from the fluid to a secondary coolant, usually water or a water-glycol mix. The cooled fluid is then cycled back to the seal chamber. HELIFLOW® exchangers come in a range of standard sizes, and custom configurations are also available.
