Improved reliability, performance and energy efficiency can result from pump system assessment. pump system optimization, pump efficiency
Due to a recent thrust bearing failure in one of our deep well pumps, we would like to determine the down thrust on the bearing from the pump. Is there a simple way of calculating this?
Repairing multistage, segmental diffuser, boiler feed pumps and maintaining the original performance can be difficult and challenging. In this case study, a comprehensive inspection and repair program was applied to rebuilding six boiler feed pumps to improve MTBR and hydraulic performance to meet system demands.
A look at new tool that predicts how pumps and systems interact.
A few years ago, Corbin Spitzer from Spitzer Associates (Houston, Texas) correctly challenged a view in my article "10 Steps to Proper Alignment" (Pumping Prescriptions, October 2005). Spitzer criticized my recommendation of leaving the alignment shims in the grout.
Recently I was involved in a discussion with some folks from Chevron about the effects of viscosity on centrifugal pump performance. Here are some excerpts from our discussion:
