Using Cornell Pump RunDry® to Prevent Seal Damage

November 20, 2025

Running a centrifugal pump without liquid is one of the fastest ways to damage mechanical seals. Even a brief run-dry event can overheat the seal faces, crack elastomers, and dramatically shorten pump life. Cornell Pump developed the RunDry® system to address this problem directly, giving operators a reliable method to protect seals during low flow or no flow conditions.
