Motor data
Standard motors in the CR range
Motors used in the CR pump range are:
• Grundfos ML or MLE motors
• Grundfos specified Baldor
®
motors
The information in the tables below applies to following
motors type and size:
Grundfos CR pumps are supplied with heavy-duty
2-pole, NEMA energy efficient C-frame motors built or
selected to our rigid specifications. All CR pump motors
have heavy-duty bearings for maximum thrust
requirements.
It is not recommended that an off-the-shelf
standard Baldor motor be used on a Grundfos
pump. Ideally, the best motor choice would be the
Grundfos specified motor.
Single-phase Grundfos specified motors up to 7.5 hp
have a built-in thermal overload switch.
Other motor types are available (i.e., Explosion proof,
Mill and Chem duty, Premium Efficiency, etc.); consult
local Grundfos company for more information.
Pumps supplied by Grundfos Canada are normally
supplied with motors from other manufactures. 575 volt
motors meet NEMA energy efficient standards.
Dimensions and data will vary, contact local Grundfos
company for more information.
All values are subject to change without notice.
