During all dismantling and re-mounting operations, takecare
to protect the parts against any dropping or bumping that
might damage them.
6.1 Checking of parts
The piston
301
and the cylinder
201
are active parts
(wear parts) on which the pump's efficiency directly
depends. It is therefore advisable to regularly check the
pump's efficiency and replace the cylinder / piston if it
decreases.
In addition, as using a cylinder / piston that is too worn
may damage the pump's transmission system, it is advi-
sable to replace the cylinder / piston if the maximum
acceptable wear dimensions defined in the table below
are reached.
As changes in the pump's efficiency depend on the
conditions of use (pressure, rotation speed, liquid pum-
ped, etc.), MOUVEX recommends that users define the
monitoring ranges and the preventive maintenance
schedule according to their own experience.
6.2 Checking of seals
Seals material are intended for use in normal conditions
in food process. In order to ensure a reliable sealing on
S series pumps we recommend to :
- do an inspection of the seals every three months (this
time could be shorter if using the pump in hard condi-
tions. Contact the manufacturer for advice if necessary).
- replace the pump sealing every two years.

NOTICE
When disassembling the piston nut 304, if the
enclosed thread surfaces have become soiled,
we recommend cleaning them as follows :
clean the inner thread by washing, rinsing and
sterilizing the whole part (i.e. with a steam ste-
rilization), then remove any impurities from the
external threads by washing with a brush follo-
wed by rinsing with a bactericide solution befo-
re reassembly.
