Wilo – other models: the collective page of pump motors outside the named ranges, exclusively two-pole, MHI motors and the IL/DL/MVI ranges, 0.75 to 2.2 kW, foot and flange versions
Wilo, founded in 1872 in Dortmund, is one of the large European makers of pumps and pump motors. This page gathers the motors the Australian energy-efficiency register could not assign to a named range, including pure spare-part numbers such as 3514167 and short codes such as MVI, IL, DL and IPL, referring to Wilo's pump ranges (vertical multistage and inline centrifugal pumps). Some motors are recorded in the register explicitly as "MHI Motors … by Wilo France S.A.S." and thus come from Wilo's French subsidiary.

The register lists here 20 versions with 0.75 to 2.2 kW, uniformly two-pole, full-load efficiencies from 81.8 to 87.5% and at 75% load from 82.6 to 88%. The build form ranges from the flange version frame size 100 to the foot versions 80M and 90M, protection is IP54 and IP55. Testing followed the 2019 GEMS determination and AS/NZS 1359.5:2004, with test methods A, B and 2-1-1B; eleven of the 20 motors carry a documented High Efficiency classification, one of them at the 2005 level.
As pump motors, all 20 versions are two-pole, matched to the typical centrifugal-pump speed of around 2,900 rpm, and cover the lower power segment of heating, cooling and circulation pumps, closely tied to Wilo's own pump range.
When buying used, the condition of the mechanical seal and shaft seal, a checked insulation resistance of the winding, bearing and fan-cover condition, and a legible nameplate with build form, output and voltage rating matter; on the flange motors, the condition of the centring to the pump housing should also be checked. Spares run through the Wilo service network.

The Wilo 4210739 delivers 0.8 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.
