Grundfos – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, GSM/GTM/MG designations, 0.75 to 160 kW, manufactured mainly in Hungary, Taiwan and Malaysia
This page gathers the Grundfos three-phase motors the Australian energy-efficiency register does not assign to a named range. Grundfos is a Danish pump manufacturer headquartered in Bjerringbro, founded in 1945, one of the world's largest pump makers; the motors listed here are overwhelmingly drives for the company's own pump ranges rather than industrial motors marketed in their own right. The type designations follow a scheme of range code (GSM, GTM), power in kW and IEC frame size with a foot-form letter, e.g. GSM11-160M-2 or GTM0.75-80M-4; for six motors the motor family MG is additionally recorded, which Grundfos runs as a separate standard-motor range.

The register lists here 106 versions with 0.75 to 160 kW, two- to four-pole, full-load efficiencies from 76.2 to 95.7% and at 75% load from 72 to 95.6%. Protection rating is IP55 for 85 motors, the rest spanning combinations from IP44 to IP66; frame sizes are mostly recorded as foot-mounted from 80 M to 200 L. Manufacturing countries recorded are Hungary, a combination of Taiwan, China and Hungary, Malaysia, Germany, and a four-way combination of Vietnam, Singapore, Malaysia and China. Testing followed AS/NZS 1359.5:2004, the 2019 GEMS determinations and the older 2000 Legacy standard; for 56 of the 106 motors a High Efficiency Level is documented, spread across the 2005, 2018 and 2001 levels.
The page thus shows how broadly Grundfos supplies its pump programmes with standard motors from various plants across Europe and Asia; in the pump market Grundfos competes chiefly with Wilo, KSB and Xylem, with motor choice varying by efficiency class depending on the target market.
When buying used or replacing, what matters is bearing condition and a checked insulation resistance of the winding, the seal of the shaft entry to the pump, visible corrosion on the motor housing in wet installations, and a legible nameplate with frame size, pole count and efficiency class; for pump motors it is also worth checking that motor and pump curve actually match. Spares run through the Grundfos service network.

Frequently asked questions
How much power does the Grundfos MG112MC2-4.0 have?
The Grundfos MG112MC2-4.0 delivers 4 kW.
What to check before buying
- Match the data plate against the order: frame size, mounting and rating have to agree.
- Check the ingress rating against the installation site — outdoors or in dust the demands differ.
- Hold the mounting form and dimensions against the existing seat before ordering.
- The pole count sets the speed — when replacing an older unit, compare this first.
- For used units, ask about winding condition and bearing play.
- Ask about parts availability for this series — the running costs hang on it.
