Cavitation damage can drastically shorten the life of the pump impeller, mechanical seals, bearings and possibly other pump components, and cavitation typically starts in pumps with NPSH Margins (NPSHA/NPSHR) of around 4.0 and higher. This means that cavitation exists in a high percentage of installed pumps. But not all pumps that experience cavitation will be damaged. So the big questions becomes, not will my pump cavitate, but will the cavitation that likely exists cause damage to my pump. Allan Budris has developed a relatively simple means of answering this question in the form of “Suction Energy”. This paper defines Suction Energy, Suction Energy Levels, Suction Energy Gating values for various pump types and how Suction Energy Ratios and NPSH Margin Ratios can predict relative pump life. Also explained are how Suction Energy can also predict suction recirculation damage, and when suction piping is critical to dependable pump performance. Suction pipe lengths are suggested for low and high pump suction energy levels. This new method for predicting cavitation damage in centrifugal pumps, which has been adopted by the Hydraulic Institute and major pump companies, can save thousands of dollars in unnecessary maintenance costs.
