9.3   SPARE PARTS

To enable the effective and timely extraordinary maintenance of the coupling, it 

is recommended to keep a small supply of parts available, especially the ones, 

which are most subject to wear or substitution.

To order the KITS, please report:

- SIZE AND IDENTIFICATION CODE of the coupling, shown on the identification 

Plate.

To submit a request for FUSIBLE PLUG or EXPANDABLE TRIP PLUG KITS, 

also specify the triggering temperature.

For  any  further  information  on  single  components  of  the  coupling,  you  may 

request  the  SPARE  PART  DRAWINGS,  specifying  the  ROTOMEC  coupling 

model.
