Supply frequency determines motor speed, and motor speed determines the pump flow, head and power draw. A pump rated at 50 Hz will not deliver its stated duty on a 60 Hz supply — and vice versa.
Where 60 Hz applies
60 Hz is the standard supply frequency in North America, Saudi Arabia, much of Latin America, and parts of the Caribbean and Pacific. Saudi Arabia is one of the few countries outside the Americas on 60 Hz.
What is in this category
60 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. If you are specifying for Saudi Arabia, 60 Hz is normally the correct choice.
FB 60Hz
The FB pump ensures efficient hot and cold water circulation, making it ideal for HVAC systems, solar-powered homes, and domestic heating.
