6.1.6 Checking the shaft seal
Mechanical seal
The mechanical seal only leaks slightly or invisibly (as vapour) during operation.
Mechanical seals are maintenance-free.
6.1.7 Shutdown
CAUTION
Heat build-up inside the pump
Damage to the shaft seal!
▷
Depending on the type of installation, the pump set requires sufficient after-
run time – with the heat source switched off – until the fluid handled has
cooled down.
CAUTION
Backflow of fluid handled is not permitted
Motor or winding damage! Mechanical seal damage!
▷
Close the shut-off elements.
ü The shut-off element in the suction line is and remains open.
1.
Close the shut-off element in the discharge line.
2.
Switch off the motor and make sure the pump set runs down smoothly to a
standstill.
