Centrifugal pump operation is a lot like hitting a baseball. If you hit the ball with the bat's "sweet spot," everything is great,"energy transfer will be efficient, vibration will be low and the likelihood of damaging equipment will be minimal. End up too far in or too far out on the bat/curve, and problems are likely to occur.
|01/01/2010||The Best Point | Run your pump at best efficiency and improve process performance - as shown on ChemicalProcessing.com
In that elusive perfect process world, a pump always operates at its best efficiency point (BEP) ," the flow rate at the point of highest efficiency. In the real world, that's almost never the case. In fact, the average pump efficiency in industrial applications is estimated to be below 40 percent.1 Process variables, pump over-sizing and other factors can cause a pump to perform at a less-than-optimum level. A key factor in improving mean time between failure (MRBF) is determining where your pump actually is operating.
