•
The pump must always work smoothly and without vibrations.
•
Do not operate without liquid and in any case avoid prolonged operation with the
discharge gate valve closed.
•
With series AS pumps never close discharge side completely.
•
Mechanical seal: check that there is no leakage along the shaft.
8.3
Extended stop
When stopping the pump for a longer time, empty the pump completely and wash it
accurately in order to avoid the formation of scales and/or encrustations. When starting
the pump again, please follow the above mentioned instructions.
8.4
Cleaning the pump
The pump does not require any special washing procedures. The washing cycles
normally used for the plant in which it is installed are quite satisfactory. When using the
pump for liquids that tend to harden or crystallize, always make sure it is washed before
periods when the machine is to be taken out of operation. This will ensure durability of
the seal and of the pump itself.
It is the user’s responsibility to ensure that the washing liquids are compatible with the
process liquid and the pump.
