Install / Failure Note

DB Series runs dry for hours without damage when equipped with a carbon bushing, and Filter Pump's MTD carbon bushings carry the same real tolerance — both exist for the intermittent-suction-loss failure mode that kills a standard mechanical-seal centrifugal pump within minutes on an acid transfer line.

Acid transfer lines lose suction more often than a spec sheet admits — DB Series' carbon-bushing dry-run tolerance and Filter Pump's MTD carbon bushings both exist to survive exactly that intermittent-suction failure mode, which matters more day-to-day on an acid duty than the peak pressure rating ever does.
