General
The lifetime of compression head components is influenced by the following factors:
- condition of plunger surface;
- processing
temperature;
- type of product;
- underfeeding of machine (insufficient feed pressure), see
technical data sheet
enclosed in chap-
ter 11 of this manual);
Some of these factors, such as wearing out of piston surface and underfeeding of the machine, lead to early
deterioration of gaskets.
Gaskets should be replaced when you notice product leaks in the sump; the work cycle can be completed
without the risk of pollution provided machine feeding is correct.
ATTENTION To avoid stopping production due to leaks from plunger gaskets of plungers, we
recommend preventive replacement of gaskets based on estimated average lifetime.
ATTENTION:
before proceeding with maintenance operations and replacement of gaskets, make sure that you
have all the spare parts and equipment you need.
