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.

Some brands (such as Hayward, Jacuzzi or Sta-Rite) may use non-standard fittings with different dimensions.

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.
Our old pump was so noisy, it was embarrassing. It must of had a bad bearing. The new one we bought is so quiet. The price was fair and arrived fast. I'll be ordering some other parts I need from you in a couple days.
My unit arrived cracked but it wasn't your fault. When I called to see what could be done you offered to send out a replacement the very same day. Can't be much easier than that. I really appreciate your help.
I did a full renovation of my pre year 2000 Catalina hot tub and it was a perfect swap out. This 5hp unit was a seamless swap out, mount and play with absolutely no issues. Be sure to check the poles on the pump as the previous pump were positioned differently. Same make and model, but the connectors in the pump were is a different order. The common white and hot red were flipped. Other than that, good to go! Thanks for the quick turn around on the order and shipping was great. Excellent customer service as always too!
Perfect replacement for my dad's old leasure bay spa. Knowledgeable staff with great shipping service. Will do business with them anytime. Thank you
Received pump very promptly, changed out with no problems. Swim spa is working just like new!
The pump worked perfect.
Thanks to the spa depot for their great service and fast shipping. Prices you can't beat as well.
Nothing wrong with the pump and wired it just like the old one, but unfortunately they weren't in the same order and configuration as the old one. Result fried a rely on the Motherboard. Wiring instructions would be great to prevent further expense from wiring wrong. Pump works fine though other than that.
spa pump direct replacement
Pay special attention to what you order. I ordered the incorrect in valve but SpaDepot to the rescue they assisted me in returning my unopened pump and send out the new one. Great service. New pump is installed and running great.
