Diffuser redesign eliminates $100,000 per year on unplanned maintenance
Download this White Paper: Chemical plant was making frequent repairs due to a high vibration issue. A chemical processing plant had been experiencing high vibration and bearing failures on their Furnace Water Circulation pumps. This
Dealloying Issues in Aging Service Water & Circulating Water Pumps
Download this White Paper: Is material quietly disappearing from your pump? The average age of the U.S. nuclear reactor fleet is 39 years old [1] and many plants are forecast to continue operating for years to come. Many nuclear pumps,
The effects of changing plant operational modes on Boiler Water Circulation Pumps
Download this Case Study: Introduction: The rise in total generation capacity of renewable energy sources such as wind and solar is resulting in traditional “base load” coal generation plants being more frequently used to follow fluctuating
Upgrade the capacity of your BWCP thrust bearing
We understand that your plant is likely operating with quicker start-ups and shutdowns, and more frequent load changes than it was originally designed. These operating modes can cause pre-mature bearing wear or, in some cases, catastrophic failure
SRVB #5-HT BWCP rotor to stator magnetic gap restack criteria
There has been much discussion over when to restack a BWCP rotor or stator for electrical performance reasons (i.e. not mechanical damage, but actual or anticipated performance degradation). There are four primary concerns with an increased
SRVB #3-Boiler Circulation Pump Cavitation
As most pump users know, that when cavitation occurs, it is the result of vapor bubbles collapsing within the impeller passages. It may be within the fluid or on the metal surfaces, and most often does cause vibration in the unit. If severe enough,
SRVB #2-Boiler Circulation Pump Vibration
All rotating equipment lends themselves to vibration measurement and analysis. During normal operation they emit a specific vibration signature. If this signature changes it provides an indication of a change in the health of the
Power Plant Cycling: Its effect on NPSHa and the damage it causes to Boiler Water Circulation Pump (BWCP) thrust bearings
