I have a large Frick machine(cant remember exact model) that the shaft seal leaks on.
The history is, the seal was suspect to be leaking, so we replaced the seal with a new one the customer had on site. However this seal had been on site since instal(15 years sitting on a shelf).

I thought after replacing the seal and that it started to leak almost straight away that the housing o-rings could have been affected due to sitting on a shelf for 15 years, so i changed the o-rings for new.

Ammonia still leaking from shaft seal.

On replacing the seal i followed the instructions and didnt find it that hard, so dont think i've done anything wrong.

Your thoughts would be very benificial.

Regards

Ian
