Start-up and operation
6.2
Checking the pump
To check that the pump is working satisfactorily, pour water into
the pump and start it momentarily. Check the direction of rotation.
Fig. 6. Listen for any unusual noises.
In pumps with water-flushed or steam-flushed shaft seals, the seal
chamber must be filled with water/steam.
Caution!
Never allow the pump to run without liquid, as this
will ruin the shaft seal.
6.3
Starting the pump
Check the following before starting the pump:
-
That the shaft guard has been fitted properly.
-
That there is unobstructed access for liquid and that the pump is
primed.
-
That the valve on the discharge side is closed.
The valve on the discharge side is closed during start-up to prevent
the motor from overloading, but should be opened again as soon as
the pump has been started.
Note!
The pump should not be left running too long without pumping
(typically 15 minutes if the pumped liquid is not
hot), because it will get warm and the priming
liquid will evaporate.
6.4
Flushing liquid
In pumps with a flushed shaft seal, check that the supply inlet for
the flushing medium is open and that the flow of the medium is
adequate (approx. 15-30 litres/hour).
