Cost Analysis of Replacing Power Plant Cooling Water Volute Casing Pumps with Mixed Flow and Variable Pitch Propeller Pumps

Overview: Replacements are being considered for a cooling water system that currently consists of four volute casing pumps. A cost analysis is done comparing the baseline versus variable pitch propeller pumps and mixed flow pumps with variable inlet guide vanes. Mixed flow pumps have the fastest payback in this application with a payback time of 0.4 years.

Field Evaluation of Different Check Valve Designs and Surge Pressure Measurement in a Municipal Water Pumping Station

Overview: During a municipal water pump station upgrade, hydraulic engineers got approval to perform field tests to assess the waterhammer (pressure surge) transients. Surge pressure measurements were taken after an induced pump power loss and subsequent check valve slam. They also developed a computer model to see how well available software could simulate the produced transients. This data was gathered to provide guidance to the municipality on future project work.
