Some Effects of Operating Pumps Away from Best Efficiency Point

Increasing pump reliability. Achieving higher efficiencies. Improving mean-time-between-repair. These goals can all be attained by understanding BEP, or Best Efficiency Point. BEP essentially defines the flow at which a pump operates at the highest or optimum efficiency for a given impeller diameter. Operating a pump at flows greater than or less than the flow designated by the BEP can cause adverse effects. Read more…

Preventing Water Hammer from Damaging Pumps and Pipes

Water hammer, also known as “surge flow”, can cause pipes to burst, create leaks at joints, and damage supports and pipe racks. This article thoroughly explains how water hammer occurs and provides 10 possible solutions for resolving water hammer issues. Read more…

Coupling or Shaft Runout

Precision alignment is critical for rotating machinery and checking Runout is a MUST. Severe runout can cause an array of issues with pumping equipment, including excessive vibration, seal wear, and bearing damage. Read this article to learn more about concentricity and how to check Runout. Read more…

Pipe Strain and Its Effect on Shaft Alignment

The best lessons are learned from industry professionals who have real-world experience with pumps. In this article, a millwright explains his experience with pipe strain, which is unwanted pressure or movement in piping systems. Read this article to learn how to identify and correct pipe strain issues. Read more…

Guidelines in Determining Allowable Values for Bearing Housing Vibration on Rotodynamic Pumps

All pumps vibrate during operation, but determining allowable values for bearing housing vibration can help avoid pump problems. This article provides guidelines on how to measure bearing housing vibration on rotodynamic pumps. The vibration measurements shared in this article can be used for operational monitoring, acceptance tests, diagnostic or analytical investigations. Read more…

Design and Application Factors Affecting NPSH Margin

Determining an acceptable NPSH margin can help you improve pump reliability and increase overall service life. Pump type, application, and physical operating conditions can affect your NPSH (Net Positive Suction Head) margin. Read this article to better understand NPSHR, NPSHA, and NPSH3, as well as several pump characteristics and applications factors that need to be considered. Read more…

Choosing a Flexible Pump Connector

Nozzle loads from pipe misalignment and thermal expansion can cause seal leakage, coupling problems, and bearing problems, so using a flexible pump connector can help you avoid these problems. This article discusses the advantages and disadvantages of rubber connectors, braided hose connectors, metal bellows connectors, and PTFE connectors. Read more…
