Consideration of the load profile while sizing the pump

Summary

The efficiency of pumping equipment is a priority for water supply providers. The main condition for the efficient operation of pumps is the correct choice of pump parameters and methods of their control in accordance with the requirements of the system. A specific feature of water supply systems is a wide variety of operating modes both within 24 hours and projected for several years. A practical example shows the need to take into account the actual and prospective modes of operating a pumping station while selecting the sizes of pumping units. An analysis of the operating modes of pumps of different sizes and control methods is given. Specific and total energy consumption was used as a criterion for estimating the best option. This provides for the efficient and reliable operation of pumping equipment throughout the entire life cycle.
