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.

Easy replacement

Only had to rotate the pump 90 degrees. Easy Peezy 30 minutes and I was done. Spa Depot ALWAYS has the parts I need to keep my hot tub going.

Very good for a larger hot tub.

This pump takes up more room than the original pump (the two cond. cans on the top original had one). and this made it hard to install in the space that the old pump took. This is a small hot tub, 250 gal. so not a lot of room. I was able to make it fit and the pump worked great after the installation.

I would buy this product again

This purchase was a perfect fit. It worked perfectly in a 15 year old spa.

Pump worked great - the only issue was the mount

I would have given this five stars, but for one item. It works great and was easy to connect to my spa. The welded on mount caused me hassle when installing. The pump I replaced was strapped into a mount and I needed to use the existing mount. Ended up cutting off the mount that came with the pump.

Not as powerful as I expected

I called in and provided the old motor number and was given the perfect replacement. Functions fine, but has half power as the old pump and I had to alter to get it to fit!

Everything I expected

I purchased this pump to replace the factory pump in my Freeflow Hot tub and its everything I was hoping for. Installation was quick and easy and the pump performs as intended. Good power, quiet operation, and everything fit just as I was hoping with no modifications. Very happy with this pump!
