COMMISSIONING/START-UP/OPERATION:
3.1
Preparations –
Fill the pump with the liquid to be pumped and vent it by means of the vent nipples
on the flanges. Pumps in mechanical seal construction must be vented too, by
means of screwed plugs, provided on the mechanical seal cover. Venting is also
necessary in case of positive suction and for hot liquids.
Pump is to be filled only once and may be filled prior to connecting the piping to
suction and delivery flanges. For all subsequent start-ups the pump will operate
with self-priming.
Check that the shaft rotates freely. Check that all auxiliary connections are ready
for operation.
Open all shutoff valves in suction and discharge lines!
Never start up the pump with the discharge side closed! If the unit is fitted with a
bypass line, see that it is closed for suction lift operation; with positive suction it
may remain open.
As the bearings are permanently packed with grease, no further greasing is
required. Bearings used are self-lubricated.
3.2
Motor –
Check the operating voltage and speed of the motor.
The speed of the 50 Hz model is 1450 rpm. The speed of the 60 Hz model is 1750
rpm.
Provide a motor tripping device!
Check the direction of rotation of the motor with respect to pump by switching the
motor on and then off again immediately. The direction of rotation of the pump is
indicated on the pump by direction arrow nameplate.
Never run the pump in reverse direction of rotation!
The electrical connections are to be made by an authorized electrician and in
compliance local regulations, in particular in respect of the safety measures to be
performed.
