Efficiency comparison pumping system

Thursday, January 25th, 2018 von admin

An increasing number of pumps are now being run using speed control in order to be able to define the dynamic volume flow. The pump’s quadratic characteristic causes the motor load to decrease rapidly at lower speeds, which results in the level of efficiency decreasing significantly. Using the diagrams, it can be seen that the ideal workload for the existing asynchronous motor is not reached, due to operation at partial loads (approx. 30%) and speeds (75%).

If the pump is then equipped with a PMSM motor that has an extended efficiency range including partial load operation, the level of efficiency can be increased by approx. 12% in this example and savings of more than EUR 250 per pump per year can be achieved (depending on the number of hours‘ operation per year).
