2.9 Preventing material damage
2.9.1 Dry running
If run dry, mechanical seals and synthetic parts can be destroyed
within only a few seconds.
 Do not allow the pump to run dry. This also applies to
checking the rotation direction.
 Purge air from pump and suction line prior to start-up.
2.9.2 Cavitation
Pipes which are too long increase resistance. This results in risk
of cavitation.
 Observe the maximum pipe length.
2.9.3 Overheating
The following factors can result in the pump overheating:
• Ambient
temperature which is too high

Do not exceed the permitted ambient temperature of 40 °C.
2.9.4 Blockages in the pump
Pieces of dirt in the suction line can clog and block the pump.

Do not operate the pump without a strainer basket or a
strainer basket handle.
 Check how easily the pump rotates before starting it up and
after longer idle or storage periods.
2.9.5 Risk of frost
