Abstract: A method for assembling a seal cartridge and a seal cartridge, wherein the seal cartridge includes a set of sealing components configured for being removably assembled to each other so as to form the seal cartridge and wherein at least one of said sealing components is configured for being secured to another sealing component and/or to a shaft casing by a tenon and mortise joint system.

Abstract: A pin locking device for assembling a first and a second sealing component of a seal cartridge which includes a pin body with a longitudinal bore, wherein an inner wall of the bore includes fixing device that cooperates with an extraction tool. The pin body has two parts arranged longitudinally one after the other. A first part is configured for fitting a pin cavity of the first sealing component and a second part is configured for fitting a locking cavity of the second sealing component. A spring configured for moving the pin body from a withdrawn position, where the pin body is entirely located within a pin cavity of the first sealing component, towards a locked position wherein a second part of the pin body is located and maintained within a locking cavity of the second sealing component while a first part remains located within the pin cavity.
