In most cases, the planning of the Grundfos UP15-10SU7P pump has some degree of priblizheniya.No it helps to select a model or a pump of several possible options quite right. You can apply an approximation in which it is expedient to combine close to the parameters regime. Figure 2 shows two versions of schedule rate. If you plan to work on option A, it is advisable to use one Grundfos UP15-10SU7P pump. He has most of the time running at optimum flow, that is quite economical. The second pump may be redundant. This is particularly true in conditions that do not allow interruptions fluid. For example, in continuous processes, as well as utilities.
Under option B appropriate to put two pumps in parallel. In this case one runs continuously in the optimal range and provides 50% of consumption. The Grundfos UP10-16BU pump – also in the optimal mode provides peak flow. This way you can apply and a block of several pumps, when the flow varies dramatically in different changeable within the flow.
Calculations show that the profitability of the use of power Grundfos pumps in some cases may be higher when compared with a powerful pump with a high pitch, variable speed shaft (Grundfos 1992) .
