Pump seals are essential components used in various types of pumps to prevent the leakage of fluids. They create a barrier between the pump's rotating shaft and its housing, ensuring that liquids or gases do not escape during operation. This is crucial for maintaining efficiency and safety in systems that handle chemicals, water, or other substances. There are different types of pump seals, including mechanical seals and packing seals. Mechanical seals are commonly used in high-pressure applications, while packing seals are often found in simpler designs. Proper selection and maintenance of pump seals are vital for the longevity and performance of pumping systems.
