Introduction to Pump Seals
Pump seals are crucial components in various pumping systems. They are designed to prevent the leakage of fluids (liquids or gases) from the pump housing, ensuring the efficient and safe operation of pumps. By creating a barrier between the rotating shaft and the stationary pump casing, pump seals help maintain the pressure within the pump, reduce energy losses, and protect the environment from potential hazardous fluid spills. There are different types of pump seals, such as mechanical seals, gland packing seals, and lip seals, each with its own characteristics and applications depending on factors like the type of fluid, pressure, temperature, and speed of the pump.
