    Why the inlet water temperature of a centrifugal pump must be strictly controlled and the hazards of excessively high temperatures.

    Why the inlet water temperature of a centrifugal pump must be strictly controlled and the hazards of excessively high temperatures.

    When a centrifugal pump is in operation, an excessively high inlet water temperature is by no means a "minor issue"—rather, it serves as the direct trigger for cavitation. The destructive power of cavitation far exceeds common perception, systematically shortening the service life of the pump unit, causing cascading failures, and resulting in irreversible economic losses. In this article, Changsha Zhonglian Pump Industry, a manufacturer of centrifugal pumps, provides an in-depth analysis—from the microscopic mechanisms to the macroscopic impacts—of why the inlet water temperature of centrifugal pumps must be strictly controlled and highlights the dangers associated with excessively high temperatures.
