Grundfos offers numerous speed-controlled pumps that are referred to as ‘E-pumps’ and which come equipped with Grundfos MGE motors with an integrated frequency converter. The manufacturing costs and material inputs are lower compared to pump solutions with external frequency converters. In addition, technical issues that may arise in connection with external frequency converters are avoided.
Finally, MGE motors have numerous additional features and advantages. In the event that no E-pump is available for a specific application, it is generally possible to operate the three-phase industrial motors offered by Grundfos via an external frequency converter. The technical information set out in the operating instructions and datasheet should be referred to in each individual case.
