The pump is the heart of the spa. Spa pumps run frequently throughout the day to
circulate hot water within your spa to help maintain temperature and help filter
the spa water. The spa pump is what circulates hot water through your spa and works
in combination of a pump and a motor. Most spa pumps last for several years before
requiring attention, however it is recommended to replace an entire spa pump when
it begins to malfunction.
Our spa pumps last years longer than competitor brands. Each switchless pump has
a 50% thicker and longer shaft than standard pumps for increased durability and
output. Shop for the perfect spa pump for your hot tub that will not only deliver
an intense hydromassage, but will keep your spa water circulating for a clean and
warm water spa experience.
MEASURING YOUR PUMP FRAME:
The entire size of your spa pump is referred to as the frame, which is important
to know when ordering a replacement pump. Spa main pumps will have a size of either
48 frame, which are approx. 5.5” diameter, or 56 frame, which are approx. 6.5” diameter.
Some motors will have the frame size on the unit.
MEASURING YOUR PLUMBING SIZE:
Plumbing size is very important, but a lot of people get it wrong and end up ordering
the wrong pump. Most spa pumps use either 1.5” or 2” plumbing fittings and a few
have 2.5” intake suction. These are pipe call-out sizes, not fitting measurements.
Spa circulation pumps (or circ pumps), are smaller than main pumps but they have to be diligent because they keep the water moving in your spa 24/7,
this provides continuous filtration and helps keep crystal clear spa water.
Pump Speed Configuration:
A 2-speed pump requires three connections, and a ground wire. The typical color coding is as follows:
- White: Common
- Black: High-Speed
- Red: Low-Speed
- Green (or bare): Ground
Refer to the wiring diagram on your pump, as some equipment systems use different color coding.
Wire orientation may vary on different pump brands.
One Speed Pump Configuration: A 2-speed spa pump can serve single-speed duty by using only the common and high
speed terminal connections, while leaving the low speed terminal blank.
*If your spa filtration or heating cycle comes on with high speed instead of low speed, this indicates that
the high and low speed wires need to be switched.
Pump Voltage & Horsepower:
All 110-120V spas use 120V pumps, however not all spas wired for 220-240V use 240V pumps, some use 120V pumps.
Read your spa’s owner's manual, and look at the label on the old pump to determine the appropriate voltage and BHP (break horse power).
The label on your old pump should also indicate the horsepower and amps required.
About Voltage Requirements:
Standard (US) household voltage varies between 110 and 120 volts. Larger appliances required 240 volts to function.
Spa motors will be designed for one of these two ranges, but keep in mind that a voltage specification of 115 volts
actually means that it is designed to function correctly in the range of 110 to 120 volts; a device which specifies
230 volts actually means it will function correctly in the range of 220 to 240 volts.< br/>
Watts = Amps x Volts. Amperage determines the size of wiring and circuit breaker/GFCI required,
and is also a factor in what your equipment controls will accommodate. Wattage is the total amount of power consumed.
Note that a 120 volt pump drawing 16 amps uses virtually the same amount of power (wattage) as a 240 volt pump drawing 8 amps.
Spa Pump Frequency:
Spa pumps are available in two different frequency configurations: 50hz and 60hz.
In North America, the line frequency is 60 HZ. In Europe and elsewhere around the world it is 50 HZ.
Some island nations also use 60 HZ. It is important to order a replacement pump with the correct voltage and line frequency
for the country the spa will be operated in.
In general for North Americans, 60 HZ pumps will be required as a replacement spa pump for spas in North America.
Please verify your current spa pump before ordering!
