15 Years of Improving Pump Reliability

Since our company inception, we have been dedicated to helping our customers improve their pump systems and reduce their pump-related operating costs.  We work with companies in varied markets in the training of personnel, specification development, root cause analysis, strategic planning, process improvement, testing and inspection audits, and computer-based training development.

 

As an independent consultant, we provide an unbiased viewpoint.  With 40+ years experience ranging from pump design inception to aftermarket repairs and inspections and root cause analysis, we have the tools to help you find the best solutions to your pump problems.

 

Below you can find examples of some of the work we have successfully completed for our customers.

 

brunswickfailure

RFP Impeller Failure

Evaluated impeller and diffuser breakage experienced with new hydraulic assembly installed in existing casing to meet new conditions required by Extended Power Uprate.  Coordinated between site, OEM, and independent group providing CFD and finite element analysis to identify changes necessary for reliable operation.

bwroggas

BWROG Gas Accumulation

Participated in expert panel for the Boiling Water Reactor Owner's Group in the Gas Accumulation Pump Roadmap project plan developed by EPRI as a response to an NRC generic letter from January 2008.  The project provided a path forward to research the risk of gas accumulation in safety-related pump systems.

rcpicon

Impeller Crack Analysis

Audited on-site inspection and provided support during failure analysis after a portion of a Reactor Coolant pump impeller vane was discovered in the bottom of the reactor vessel.  Used vibration analysis to identify root cause and evaluated possible extent of condition to other pumps on-site.

rwpumpicon

SW Pump Design Analysis

Provided in-depth design and system analysis for vertical wet pit Service Water pumps experiencing repeated bearing and sleeve failures.  Coordinated in-depth inspection with focus on data gathering and modal testing to confirm excitation of stationary assembly. Generated business cases with possible upgrades to eliminate failures and extend overall reliability and life.

nmpicon

Performance Test Failure

Worked as part of site team after new Reactor Feed Pump failed to meet specified performance requirements during testing.  Audited performance testing at OEM facility and met with OEM hydraulic designers to evaluate options going forward.  Communicated with site risks and benefits of each option and advocated accelerated timeline with OEM to minimize delivery delays.

rwcuicon

RWCU Bearing Failure

Performed failure analysis for Reactor Water Clean Up Pump (RWCU) that exhibited three separate thrust bearing failures in a short period of time.  Using inspection data, vibration testing, and discussions with Operations and Maintenance personnel, identified likely causes for failure and corrective actions.
