4.4 Shut-down
• Turn off the motor. Always avoid restarting the pump during the emptying
phase. During this process, the pump is running in the opposite direction. Restarting
it can result in the impeller coming loose and being damaged and can even cause
breakage of the shaft.
• If there is any risk of freezing, switch off the pump, drain it and preferably flush or fill it
with oil, if permitted. It is also recommended to drain the main piping (suctionand
discharge lines
4.5 Re-use
Re-use of the pump for purposes other than the one for which it was originally intended
should only be undertaken after completely draining the oil chamber and the pump
housing. Because the pump could have been used for corrosive or poisonous liquids, it
should first be thoroughly rinsed out.
• Flushing the pump out is necessary because the origin of the liquid which it contained
is not always known and, even after draining the pump, liquid can remain inside.
• During this procedure, observe adequate safety regulations and take environmental
protection measures.
• Liquids should be drained and disposed of safely, and the correct personal protection
equipment should be used. The wearing of gloves and safety glasses to protect
against possible splashes is advised.
• If necessary, pumped liquid must be neutralised and internal parts properly cleaned.
4.6 Scrapping of the pump
The same measures should be observed as for paragraph 6 "Maintenance". Disposal of
the pump should only be done after it has completely been drained. Proceed according
to local regulations.
