Installing
Install components concentrically and without tilting in
accordance with the markings applied.
WARNING
Risk of injury due to heavy components!
Pay attention to the component weight. Lift and transport
heavy components using suitable lifting gear.
Set down components safely and secure them against
overturning or rolling away.
WARNING
Risk of injury during assembly!
Install spring-loaded components carefully (e.g. mechani-
cal seal, stressed bearing, valves etc.), as components can
be ejected by the spring stress.
Observe the manufacturer's speci
¿
cations (e.g. for the
motor, coupling, mechanical seal, blocking pressure sys-
tem, cardan shaft, drives, belt drive etc.).
NOTE
Material damage due to incorrect dismounting/installation
of the pump.
Only specialist mechanics should complete dismounting/
installation work.
NOTE
Material damage due to unsuitable components!
Always replace lost or damaged screws with screws of the
same strength where required.
Only replace seals with seals of the same material.
NOTE
Material damage, fragile components.
Install ceramic parts of the plain bearing and magnets of the
magnetic coupling with care, do not strike them or knock
them.

–
Replace worn parts with genuine spare parts.
