A double mechanical seal has a cavity between the inner and outer faces where the liquid resides. In its unpressurized form, this liquid acts as a buffer between the contents pumped by the equipment and the outer environment, whereas the pressurized form creates a barrier between the two.
A mechanical seal is exposed to different type of working conditions, which can lead to issues down the line.
Mechanical seal parts are used in many industries such as metals and mining, petrochemical, food and beverage, and oil and gas. Seals are a crucial part of a process pump, and they have a direct link to the operation of the machine. It is vital to have quality engineered industrial parts as they contribute to the performance of a pump.
