5.10.1 Lubricate the bearings with oil
WARNING:
Risk of explosive hazard and premature failure from sparks and heat generation.
Ensure bearings are properly lubricated prior to startup.
1. Remove the oil fill pipe plug (319B).
2.
Fill the bearing frame with oil through the filler connection that is located on the top of the bearing
frame.
3. Fill the bearing frame with oil until the oil level reaches the middle of the sight glass or opposite
sight glass (319 or 408N). The correct volume of oil required for each size of bearing frame can be
found in the ‘Oil Volume Requirements’ section in the ‘Bearing Maintenance’ / ‘Maintenance’ portion
of the IOM.

5.11 Shaft-sealing options
In most cases, the manufacturer seals the shaft before shipping the pump. If your pump does not have a
sealed shaft, see the Shaft-seal maintenance section in the Maintenance chapter.
NOTICE:
The mechanical seal used in an ATEX classified environment must be properly cer-
tified.
The mechanical seal must have an appropriate seal-flush system. Failure to do so
will result in excess heat generation and seal failure.
This model uses these types of shaft seals:
•
Cartridge mechanical seal
• Packed-stuffing-box option
