Grundfos Pumps With MGE IE3 Motors Will Be Phased Out On 1 July

Grundfos introduces new pumps with an IE5 motor (MGE2) which replaces the present MGE IE3 motor.
This is important for several of our systems in which these improved Grundfos motors will be included.
As of 1 July 2017, pumps with MGE2 IE5 motors are introduced continuously in the following installations:

  • PS5 / 7
  • MS5 / 7
  • AM150 / 200
  • AMM150 / 200
  • Voyager 4 / 4K
  • KPV100 / 150/400
  • nVBS25-5, 25-10, 25-15, 25-20 & 25-30

Characteristics of the above systems supplied with the new MGE2 IE5 motor:

  • Machine number of 8 digits starting at 100000.
  • 500, 750, 1000 and 1500 mm cabinets will be 50 mm deeper
  • 5.5kW motor will be upgraded to 6kW
  • Please, note that pumps will get new part numbers which can be seen in the instruction manual. 

MGE2 IE5 motors up to 2.2kW have been introduced a few years ago, for which reason CP / 7, Voyager 2 / 2k, nVBS 16-3 and others are not affected by the above-mentioned.

Which are the benefits of the new MGE2 IE5 motor?

  • Permanent magnet motor
  • Pumps with motors from 1.1 kW and up to 11 kW
  • Reduced power consumption: savings of 2%
  • Higher ambient temperature: from 40 to 50°C
  • Wider voltage range: from 3x380-480V to 3x380-500V
