Split seals have components which split into two halves—​eliminating the need for costly equipment tear-down when replacing the seal; and saving hours of costly 

28/06/  · Any mechanical seal (split or conventional) can develop a mysterious, premature leak for any number of reasons. Maybe the pump suffers a bout of cavitation-induced vibration. Maybe the pump runs dry and the seal overheats. Maybe a load of sediment or crystals passes through the pump and damages the seal faces.

A split seal comes in two separate pieces. Unlike ordinary cartridge mechanical seals, these two pieces can be installed or removed from around
