Durable Waterway Executive 56 Spa Pumps are simple to install and provide years of trouble-free use. Because of our huge buying power, you'll pay less for a complete new hot tub pump (motor & wet end) than some others charge for just a replacement motor.

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.
Pump was exactly as advertised and came on time. Would buy again. Spa doesn't leak and is much quieter with the new pump.
This pump and motor was not a like and kind replacement. The specifications were identical to the original one. The installation was pretty straightforward. Remember to use new gaskets Good luck 👍
I bought a 3 and 4 hp pumps and they run very smooth and quieter than old pumps. They were easy to hook up and wire and again quiet.
Works great Very easy install
Motor fit right in and customer service was great. Had to contact them because the wiring on new motor was slightly different from old one. My fault though, diagram was right on the new motor.
Worked great. Good company to do business with!!
Everything came in when they said it would, the pump was a perfect fit. Had no problems at all on the install other than my hot tub is 8 feet off the ground and standing on a ladder was no fun. At least everything was as it was supposed to be and fit just right... Thank you Spa Depot this was my 3rd purchase from you and everything has been great with no problems at all with any order.. If you're looking for a cover for your hot tub I highly recommend Spa Depot , I called a few years ago and talked with someone there and they were super nice and very helpful for a custom fit cover...
Both pumps are working perfectly. Delivery was prompt and price was very good. I recommend this company for spa needs.
so far so good it works
Purchased this pump on 7/5/17. Used for one year then we moved, so the spa sat for a year at the new house while we built a new patio. It was completely winterized and lines blown out before moving. Hooked it back up in the fall of 2019, now the pump is making a very loud grinding noise which is most likely the bearings going out. So assuming this thing gives out soon the pump will have lasted exactly two years. And yes, I test and adjust the water quality weekly, or after each use whichever comes first.
