Supply frequency is not a detail. It sets motor speed, and motor speed sets the pump flow, head and power draw. Running a pump on the wrong frequency shifts it away from its design duty point and can overload the motor.
Where 50 Hz applies
50 Hz is the standard supply frequency across Europe, most of the Middle East, Africa, Australia and much of Asia.
What is in this category
50 Hz variants across the Niagara range — domestic, submersible, end suction, horizontal and vertical multistage models.
Before you order
Confirm the supply frequency at the installation site, not the country of purchase. If you need 60 Hz, see our 60 Hz category.
FB 50Hz
