Horsepower Ratings
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.

From the start the customer service is top notch. All of my questions were answered and the person I talked to made sure of the pump I was getting was going to fit. Fast shipping and the pump fit and worked as planned. Thank you

Spa Depot staff help me spec the best replacement pump for my marquis spa. The unit arrived promptly, and in perfect condition. Spa Depot instructions for replacement were helpful. This is definitely a DIY project if you want. The job takes about two hours, unrushed. The unit is working great. Now to see how long it lasts

Installed in spa and worked as expected. The delivery time as very good. The price was better than the local spa store. If I ever need a pump again I will certainly buy it from SpaDepot. Thank you very much.

Called in and confirmed but it still did not fit the OEM spacing in my 2010 Grandee. Major plumping work to get it to fit correctly .

I was struggling to assure I got the right pump and motor in that what I was seeing and what was measured was not the same. SpaDepot customer support asked for a few pics of my old one and matched it up with this item as what I needed. Perfect fit, only needed to turn pump 90 degrees for a side discharge. Price was equal or better than what I was seeing online at other places, but even for a few more bucks, the support is great. Pulled wires from old motor and easily connected to the new one. Pump was up and running quickly. Been installed for 2 weeks now, no issues noted. Noise level, about the same as the old one.
