Pump dry running is a common challenge in industrial processes, especially in chemical fluid handling. Dry running occurs when no liquid flows through the pump—such as during closed-valve operation, inadequate suction pressure leading to cavitation, or sudden flow fluctuations. This quickly causes the lubrication film to disappear, resulting in direct contact between bearing components. Bearings like SiC (silicon carbide) are particularly vulnerable to mechanical shock, often cracking or burning under such conditions.
To mitigate the risks associated with dry running, QEEHUA PUMP offers intelligent pump protection systems. These systems automatically activate protective mechanisms upon detecting dry running, preventing damage caused by a lack of lubrication. This not only extends the pump’s service life but also reduces downtime and maintenance costs.
