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. (
▪
The pump has been primed with the fluid to be handled. The pump has been
vented. (
▪
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. (
6.1.2 Filling in the lubricant
Versions ILN, ILNC and reinforced sizes of version ILNR
The bearings are closed and grease-packed for life. They do not need to be re-
greased.
Version ILNR
The bearings are closed with NILOS rings on both sides and filled with high-quality
polyurea high-temperature grease. (
Section 7.2.2.2, Page 44) The bearings may
overheat during commissioning. To prevent this from happening, a speed of 800 rpm
is recommended for the running-in process (24 hours).
6.1.3 Checking the shaft seal
Mechanical seal
The mechanical seal only leaks slightly or invisibly (as vapour) during operation.
Mechanical seals are maintenance-free.
Double mechanical seal
DANGER
Excessive temperature of barrier fluid (pumps with double mechanical seal)
Explosion hazard!
Excessive surface temperature
▷
For pumps with double mechanical seal, make sure that the barrier fluid's
temperature does not exceed 60 °C.
6.1.4 Priming and venting the pump
CAUTION
Increased wear due to dry running
Damage to the pump set!
▷
Never operate the pump set without liquid fill.
▷
Never close the shut-off element in the suction line and/or supply line during
pump operation.
Prior to commissioning and after it has been shut down for a prolonged period of
time:
