Finish Thompson's DB Series can run dry for hours without damage when equipped with a carbon bushing — a real, vendor-stated tolerance for the intermittent-suction-loss failure mode that kills a standard mechanical-seal centrifugal pump within minutes.
Chemical processing transfer lines lose suction more often than a spec sheet admits — DB Series' carbon-bushing dry-run tolerance and UCR's 300 psi/250°F envelope cover two different edges of the same problem: don't seize when suction drops, don't degrade when the process runs hot.
