2.9 Preventing material damage
2.9.1 Leakage and pipe breakage
Vibrations and thermal expansion can cause pipe breakage.
Î
Install the pump in a manner which reduces structure-borne and
airborne noise transmission. When doing so, observe relevant
regulations.
If the pipe forces are exceeded, leaks can occur at the flange
connection or the pump itself.
Î
Do not use the pump as a fixed point for the pipe line.
Î
Connect pipes free of load and mount them elastically.
Install compensators if necessary.
2.9.2 Dry run
If run dry, mechanical seals and plastic parts can be destroyed within
only a few seconds.
Î
Do not allow the pump to run dry. This also applies to checking the
rotation direction.
Î
Purge air from pump and suction line prior to start-up.
2.9.3 Cavitation
Pipes which are too long increase resistance. This results in a risk of
cavitation.
Î
Ensure that the suction line does not leak.
Î
Observe the maximize suction pipe diameter.
Î
Only switch on the pump when the valve on the delivery side is
opened halfway.
Î
Open the valve on the intake side completely.
2.9.4 Overheating
The following factors can result in the pump overheating:
y Excessive pressure on the delivery side.
y Built-in or external overload switch set incorrectly.
y Ambient temperature which is too high.
Î
Do not operate the pump with the valves closed.
Î
For pumps with a three-phase motor, install built-in or external
overload switch and set them correctly.
Î
Do not exceed the allowed ambient temperature.
