Self Aligning stationary seat makes easier conversion of gland packed pumps to mechanical seal as there is no need to machine the pump casing perpendicular to the shaft. It can replace most of the existing stationary seats without any modifications. It has uniform face load regardless of the degree of misalignment of the gland with respect to the shaft. Even face wear regardless of the type or make of mechanical seal used against it. It is free from distortions due to over-tighting of gland.
