Preparatory work

The pump was designed and assembled in accordance with the latest technical standards so that it will work reliably
for a long time under normal operating conditions. This requires you to heed all requirements and notes. Small oil
residues in the area of the floating-ring type shaft seal on delivery are harmless; however, they must be removed
before lowering or submersion in the pumping medium.
Please check the following points:
• Cable routing – no loops, slightly tautened
• Check temperature of the pumping medium and submersion depth
• Clean the pump sump
• The discharge and suction pipe system must be cleaned and all gate valves opened.
• The pump housing must be flooded i.e. it must be completely filled with the medium and not contain any air
whatsoever. Venting can be carried out using suitable venting devices in the system or, if available, through
venting screws on the discharge muff.
• Check the accessories, pipe system and suspension device for a tight and correct fit
• Check any level controls and/or dry-run protection
Perform an insulation test and check the filling level before putting into operation.
• Following a longer period of storage, the product must be cleaned of soiling such as dust and oil deposits before
putting into operation. Check impellers and propellers for smooth running,m check the housing coatings for any
damage.
Check the filling levels (oil etc.) of the individual products before putting into operation and top up as
necessary.
