Why are specially designed seals important in pumps for controlled circulation boilers?

Specially designed seals are crucial in pumps for controlled circulation boilers primarily because they must effectively handle high pressure water and maintain the integrity of the system. In controlled circulation boilers, the water is often under high pressure, which raises the saturation temperature of the water, making it essential for the seals to prevent any leakage.

Under high pressure conditions, the seals help maintain a tight seal against the surrounding environment, preventing water and steam from escaping. This is important not only for efficiency but also for safety, as any leaks could lead to hazardous conditions.

Additionally, these seals are engineered to withstand the specific thermal and pressure profiles of the system, thereby ensuring optimal performance and reliability of the pumps. If the seals were not specially designed for high pressure and high temperature scenarios, the risk of failure increases, potentially leading to disruptions in the circulation process and compromising the operation of the boiler system.
