6.1 Commissioning/Start-up
6.1.1 Prerequisites for commissioning/start-up
Before commissioning/starting up the pump set, make sure that the following
conditions are met:
▪ The pump set has been mechanically connected as specified.
▪ The pump set has been properly connected to the power supply and is equipped
with all protection devices. (ðSection5.7,Page24)
▪ The pump (volute casing) has been primed with the fluid to be handled and has
been vented. The minimum fluid level as per general arrangement drawing is
observed. (ðSection6.1.4,Page29)
▪ The direction of rotation has been checked.
▪ All auxiliary connections required are connected and operational.
▪ The lubricants have been checked.
▪ After prolonged shutdown of the pump (set), the activities required for returning
the equipment to service have been carried out. (ðSection6.4,Page37)
▪ The coupling alignment has been checked.
6.1.2 Filling in lubricants
DANGER
Excessive temperatures as a result of bearings running hot or defective bearing
seals
Explosion hazard!
Fire hazard!
Damage to the pump set!
▷ Regularly check the lubricant level.
▷ Check that the oil lubrication system is working.
DANGER
Ignition of oil escaping onto hot surfaces
Explosion hazard!
Fire hazard!
Damage to the pump set!
▷ Regularly check and (if necessary) replace the sealing of the reservoir.
▷ Check the labyrinth seal of the reservoir for wear; replace it if necessary.
NOTE
The rolling element bearings are usually lubricated with grease. Any deviation (e.g.
oil lubrication) is indicated in the general arrangement drawing.
Grease-lubricated bearings Grease-lubricated bearings have been packed with grease.
Oil-lubricated bearings Fill the bearing bracket with lubricating oil.
Oil quality see (ðSection7.2.3.2.2,Page42)
Oil quantity see (ðSection7.2.3.2.3,Page42)
