6.2 CHECKING OF PARTS
The piston
301
and the cylinder
201
are active parts
(wearing 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.
MOUVEX offers its customers a "Standard Exchange"
service, consisting of the repairing of worn parts, to allow
parts to be reused without reducing the pump's efficiency.
In order to benefit from this service, the parts must be
within the minimum wear dimensions for Standard
Exchange defined in the table below :
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.
BE CAREFUL WITH THE WEIGHT OF
THE PARTS WHEN THEY ARE BEING
REMOVED.
WARNING
The weight ot the parts can
be dangerous and may
provoke bodily injuries or
material damages.

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
sterilization), then remove any impurities
from the external threads by washing with a
brush followed by rinsing with a bactericide
solution before reassembly.
