An impeller should never run dry. Running an impeller dry, even for a short period, can lead to significant damage due to overheating and increased friction. In most cases, impellers are designed to operate within a few seconds to a couple of minutes without damage. However, to avoid compromising the impeller's lifespan and efficiency, it's critical to ensure it's always operating with the intended fluid -- typically, this means less than 30 seconds is considered safe for most types. Always consult the manufacturer's guidelines for the specific equipment in use.
