Which component helps in protecting a pump from thermal shock?

The component that helps in protecting a pump from thermal shock is the water jacket. A water jacket effectively serves as a protective layer around the pump, helping to moderate temperature fluctuations that might occur during operation. This moderation is crucial because sudden changes in temperature can cause thermal shock, potentially damaging the pump or its surrounding components.

The water jacket circulates coolant or water to absorb excess heat, keeping the temperature consistent and preventing the pump from overheating. By maintaining an optimal temperature range, the water jacket helps extend the life of the pump and ensure consistent performance in refrigeration and HVAC systems. This protection is particularly important in systems where the pump is subject to rapid on-off cycles or significant variations in load, thereby increasing the risk of thermal shock.
