5.2 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.
