7. Startup
The pump must not run dry.
FM
Dry running can cause ignition hazard.
Do not open the clamp during
operation.
The pumps are fitted with S-tube
impellers. S-tube
balanced, which reduces the vibration
during operation. If the pumps are
started with the pump housing
containing air, the vibration level can
be higher than normal operation.
Local balancing of the S-tube
impellers may damage the wet
balancing and lead to higher vibration
levels during operation.
The pumps are designed for
continuous operation, both for
submerged- and dry installations.
