API 610 Cooling Water- Pedestals
API 610 Cooling Water- Pedestals
(OP)
I spent a good bit of time over the weekend looking for information on bearing housing, stuffing box jacket, and pedestal cooling. Does anyone have links or more information documenting the current philosophy on piping cooling water to these parts of a pump? I'm fairly certain that Heinz Block has published something recently on this topic.

Please explain: Jacketed cooling on a bearing housing can actually increase bearing temperature and shorten bearing life.
I'm not a pump expert, and am curious as to why this happens. Thanks.

Another problem with jacketed cooling can be condensation. In very wet environments, the top of the housing on a pump that is not running may cool down below the dew point of the surrounding air and condense moisture in the oil. This would be most likely in someplace with high humidity.

Jacketed bearing housings are not a good idea for the reasons mentioned as well as the potential for contamination on older pump designs if the jacket integrity is compromised. We have witnessed this happen at our site on several older Union pump designs that at one time utilized jacketed bearing housings.
