Before we start to discuss "Optimum Pumping Conditions" let us first see what Webster's Dictionary gives as the real meaning of "optimum": "The best or most favorable degree. Best, most favorable or most conducive to a given end, especially under fixed conditions." The first and most important key to optimum pumping is the establishment of fixed conditions. As we all well know, the basic purpose of any pumping installation is to pump fluid from the well to the surface. In order to establish a set of fixed conditions around which we can establish optimum pumping, we must consider all of these factors which are most important and then we must decide to what degree they really are fixed or stable.
