6.3.8. LUBRICATION SYSTEMS
Refer to APPENDIX A for instructions on correct connecting and commissioning lubrication systems.
The auxiliary flushing must be connected to the connections provided on the pump.
This is necessary for the correct lubrication of the mechanical seals and bearing bushings.
IMPORTANT!
Absence of and incorrect lubrication can lead, in addition to damage to the bearing housing and/or
sealing parts, also to the triggering of combustion reactions caused by overheating due to friction.

MECHANICAL CHECKS AND PRELIMINARY CHECKS
Before proceeding with the commissioning of the pump, it is necessary to proceed with the following checks:
6.4.1. COUPLING GUARD
IMPORTANT!
According to the security rules, pumps can work only if the coupling is correctly protected. If not
included in the supply, it must be installed by the final user.
6.4.2. ROTATION
Check that the pump rotates freely by hand.
6.4.3. BEARING LUBRICATION - FIRST GREASING
6.4.3.1.
Lubrication with grease
The bearings: before shipping the pump the bearings are previously greased with high quality grease.
After start-up, they must be refilled with the quantities indicated in the "first lubrication" table.
The "group" is indicated in the "GROUP PARTITION" paragraph.
