Thermal management in well service pump packing addresses heat generation from friction between moving surfaces, heat input from hot pumped fluids, and the imperative to dissipate this thermal energy to prevent packing temperature excursions that accelerate chemical degradation, reduce material strength, increase wear rates, and potentially cause catastrophic packing failure with loss... https://globalsealstech.com/product-category/oil-gas-seals/high-pressure-water-pump-seals/
