Weird and Wonderful Pump Failures - Calgary Pump Symposium

Start-up and Operation issues:

There are more failures of a similar nature…..even on the first
unit with the repaired base-pad, the tighter warm-up controls
and more accurate hot alignment.
Other issues with the units are discovered
• Seal failures due to poor balancing of seal flush rates to
each end of the machine…the piping gets changed.
• More insulation is added to the casing, balance line loop
and warm-up piping to prevent blockage.
• Modifications to warm-up piping are proposed to improve
flow control when units are cold but never implemented.
