| dc.description.abstract | Four 580 HP cooling tower feed pumps were upgraded by retrofitting improved
bowl assemblies with enclosed stainless-steel impellers.
Pumps exhibited capacity limitation up to 50% of rated and cavitation damage in
original semi-open cast iron impellers, requiring continuous operation of all
installed equipment, including the stand-by pump, to cover plant requirements.
Performance of the pumps was optimized by rework of new impellers and stand
testing to satisfy guarantee point and improve efficiency to accommodate power
limitation of existing drivers.
As a result, rated capacity was recovered, allowing one pump in stand-by, with a
significant reliability improvement and considerable savings in maintenance costs,
together with a lower capital investment compared to the replacement of the
complete units. | en |
