Choosing a pump based on Horsepower (HP) can be misleading. The horsepower listed in your spa manual or on old pump's label may be overinflated, inaccurate, or even left blank. Horsepower ratings are often listed as Break Horsepower (BHP), which is not the same as continuous horsepower. Selecting a pump with too much power for your spa can cause significant damage.
To avoid choosing the incorrect pump, use the Amperage rating listed on the old pump's label to find the correct replacement instead of the horsepower. The amperage rating is listed with both high/low speed for a 2 speed pump.
Determining Spa Pump Plumbing Size
Pump plumbing sizes are nominal and not actual outside diameter (O.D.) of the threaded intake or discharge. Use a tape measure and check the diameter of your old pump thread size.
- 1.5” Pump thread measures approx. 2-3/8” O.D.
- 2.0” Pump thread measures approx. 3” O.D.
- 2.5” Pump thread measures approx. 3-5/8”
Orientation of Wet End
Pump wet ends can be oriented in 90º increments to meet your installation requirements. Loosen the four through-bolts from the back of the motor and pull them back enough to disengage. Then rotate the wet end to the desired position realign and re-tighten the bolts.
Side or Center Discharge
The two spa pump form factors refer to the outflow or discharge fitting on the Wet End. Your old pump will be either Center Discharge or Side Discharge.
In most cases you need to match the existing form factor to get the components to match up. If you can use either form, select Side Discharge, which is more efficient than a Center Discharge pump of the same horsepower.
Motor Frame Size
The physical size of the pump motor is referred to as frame. 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.
Since motor manufacturers do not label frame size consistently, you should determine a motor's frame size by measuring the spacing between the through-bolts on the back of the motor. Bolt spacing on a 48 frame motor will be less than 4 inches. A 56 frame motor's bolts will be spaced more than 4 inches apart.
Note: Because of their lower cost and compact size, most spa pumps in service are 48 frame. The larger 56 frame motors are a little more expensive and somewhat stronger. They tend to operate a bit cooler than 48 frame units, which can mean longer service life.
Configuring a Pump for 2 or 1 Speed Use
Our 2-speed pumps can easily be configured for 1-speed. Wire the common and high speed terminal connections, while leaving the low speed terminal blank.
WARNING: Cancer and Reproductive Harm
The pump was a perfect match and easy to install. I hope it lasts as long as the original one.
This is the second one I have replaced in 18 months. I would have opted for another brand but was this was the only 2-speed/ 2"" opening I could locate at the time.
just what I needed ,got it super fast ..!!
SpaDepot support helped me locate a replacement for a Flo-Master XP2. Installation was relatively simple and it's been working great for a week or so. Instructions are not great, but I took a photo of how the old one was setup and just copied the connections for the new one.
Good advice on choosing the pump I bought and any others questions I have had on my hot tub
I would use them again for other parts
Received the correct replacement with your help, even more powerful .
It worked perfectly for our hot tub.
We recently bought a house that came with a 6 person spa that is 26 years old. It had all the original equipment, and it hadn't been working for at least 4 years. I replaced all the components (2 pumps, blower, ozonator, control box) and re-plumbed the spa all with parts from SpaDepot. We now have a perfectly usable spa with new equipment. I spent a fraction of what it would cost to replace the spa or hire someone to repair it.
Used for a spa.
