What is a potential consequence of sustained low flow and high temperature in a pump?

Sustained low flow and high temperature in a pump can lead to the seizing of the pump. When a pump operates under conditions of low flow, the fluid does not circulate adequately, which is critical for maintaining proper lubrication of the pump components. High temperatures can compound this issue, as they may cause the lubricating properties of the fluid to deteriorate or even lead to vaporization of the fluid.

Without sufficient flow to cool and lubricate the internal components, like bearings and seals, the friction and heat generated can increase significantly. As the temperature rises further, it can lead to thermal expansion of components, potentially causing them to bind or seize. In extreme cases, this can result in severe damage to the pump, necessitating extensive repairs or even complete replacement.

The conditions described pose significant risks to the integrity and function of the pump, directly correlating with the potential for seizing, which is a critical failure mode that practitioners in the field must be vigilant against.
