The mechanics of vane passing frequency vibration
The colour map is from a water injection pump with 7 impeller and 12 diffuser vanes running at 5000rpm Fig 1 An example where vibration occurs over a narrow range of flow.
CFD ANALYSIS OF MIXED FLOW IMPELLER
pump impeller. Implosions occur on each of the vanes of the impeller causing excessive noise. The hydraulic effect on the pump is a significant reduction in performance. The mechanical effects can include shock waves and vibration which may result in damage to the impeller vanes, bearings, and seals. 2.2 Vortexing
Focus on Fundamentals (Part One): Centrifugal Pumps
Part One focuses on centrifugal pumps with an overhung impeller. The heart of any centrifugal pump is the impeller. Fluid enters the impeller through the "eye" and is "centrifuged" (hence the name) to the impeller periphery, with assistance from the impeller vanes. Impeller designs can be open or closed, with one or many vanes, or …

Solids Handling Impeller. Two-vane, semi-open, solids handling impeller handles up to 3" (76 mm) diameter solids, depending on pump model. Pump out vanes on impeller shroud reduce foreign material buildup behind impeller and reduce pressure on seal and bearings for extended pump life. Exclusive Abrasion-Resistant Seal
Sufficient NPSH Margin Important to Pump Reliability
The correlation between the NPSH Margin Ratio and pump reliability is further confirmed by recent field tests, which measured the pressure pulsation in a high suction energy sewage lift pump, as shown in figure 5. This pump experienced high vibration and cavitation damage to the impeller surface after 1,000 hours of operation at …
