Spa Pump Frequency
Hot tub pumps come in two different frequency configurations: 50hz and 60hz.
It is important to order a replacement pump with the correct voltage and line frequency for the country the spa will be operated in.
European countries also require a CE marking on the 50hz replacement hot tub pump.
In North America, the line frequency is 60 hertz. In Europe and elsewhere around the world it is 50 hz. Some Island nations and others also use 60hz, so you must first know the line frequency of the country you live in. In general for North Americans, 60hz pumps will be required as a replacement spa pump for spas in North America.
Europeans will require a 50hz replacement spa pump (and most

If you are in Canada, it's a 60hz pump. You still need to know if it is 120v or 230v.
What are the 60 hz countries?
Countries whose electricity is delivered with a line frequency of 60 hertz are some of the following:
American Samoa, Anguilla, Antigua, Aruba, Bahamas, Belize, Bermuda, Brazil, Canada, Cayman Islands, Columbia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guam, Guatemala, Guyana, Haiti, Honduras, parts of Western Japan, South Korea, Liberia, Mexico, Montserrat, Nicaragua, Panama, Peru, Philippines, Puerto Rico, Many of the Leeward Islands, Saudi Arabia, Tahitit, Taiwan, Trinidad and Tobago, U.S.A. Venezuela and Virgin Islands.
Most other countries in the world operate at 50hz. and would require a 50hz replacement pump.
60 hz pumps running on a 50 hz supply will run slower with more torque and a chance they can overheat. The result of using the wrong line frequency in this case can reduce peak flow rate by 15% or more and as much as a 30% drop in peak head pressure.
Newer pumps may be rated and designed for operation at either 50 or 60hz, but establishing your line frequency when ordering a replacement pump is required to get the right type.
Whether you are adding a Waterway, Vico, Aquaflo or other brand hot tub pump, make sure you order either 60 hz pumps for North America and other 60hz locations, or 50hz pumps for Europe and much of the rest of the world.
Knowing both the operating voltage of the pump (not of the spa as that can be different) and the operating frequency will assure you have the correct motor mounted to your pump for your location and type of spa.
Remember the pump consists of the correct electrical motor that spins the shaft which turns the water impeller which moves the water. A pump is made up of the correct motor and the matching wet end along with a sealing gasket in between the 2 parts which makeup a complete pump.
Also note most replacement pumps do not come with a power cord, so you may need to use the existing cord that has the right plug for your spa pak.
