Durable Waterway Executive 48 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.
Matched up the specs on this pump to the one in my spa and bought it because it had good reviews and was $100 less than the OEM pump. It showed up really fast and fit perfect and the install was simple! Great product so far!
I only buy my spa and pool products from this site! Great customer service and reasonable prices as well. Super fast shipping as well. This pump is just what I needed and works great!!
Worked like it's supposed to.
The secondary pump on hot tub was leaking like crazy, so time for new one, with assistance from tech support, it was decided this one was best fit. With short wait time for shipping, I was able to get new pump in its spot, had to make a minor alteration to flex pipe brackets to allow the unions to line up perfectly straight. After that it was breeze to continue installing into space and wiring into the control panel, and now tub is up and running again better than brand new!
Can't use it yet, the plastic drain plugs break off before getting completely tight, will have to try and get a steel bolt of the same threads.....
Replaced a Hot Spring vanguard watkins wavemaster 7000 pump and saved $400 by getting this pump. Easy hookup. Runs quiet too.
I was very impressed with the expert assistance from Spa Depot. He deciphered the motor/pump numbers and specs to give me the level of comfort I needed to place the order. I installed the new pump and I am very pleased with the performance. The price was less than half of what the local pool and spa dealer wanted to charge me.
1/3 the price when buying directly from Spa Depot. Perfect fit up and runs like a champ. Could not be happier with product!!
Great Company and products. Assisted me in all aspects of the purchase, installation and operation of my hot tub replacement parts. Highly recommend these guys.
Dropped in perfectly to replace my old pump which was a big bonus. Only problem was drain plug size was slightly smaller that any standard out there and I could NOT get anything to thread into it. Order drain plug to hose fitting from spa depot and waiting to test now.
