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.

Very good details for the product

Measurements were right on, I was a little cautious as I didn't have much room, was very glad that it matched up where my old pump was, works great.

My go-to spa guys

I didn't do my homework and initially ordered the wrong pump. I contacted customer service with my make and model and they got back to me within the hour with the correct pump that my spa needed, along with a FedEx return label. It all couldn't have been easier! When the correct pump arrived, it was well packaged and included straightforward directions. I had to make a couple of easy adjustments for it to fit my Sundance Spa, but it was easy peasy. This is my second replacement part purchase with Spa Depot, and I have decided to move my spa consumables business to them as well. Purchasing filters, chemicals and such from Amazon is a tad bit easier, but I'm happy to throw my business to a company who will also backup their products with expert knowledge. #sweepstakes

No

Total length of pump is different than the original which required an awkward amending of plumbing. Plus the wiring instructions were different than what my pump was configured. Disappointing.

Not sure I would buy this product again

I was told by the salesman that the bracket on the pump wouldn't matter and that the pump would work in my spa. The pump works but the bracket....not so much. If I could find it without the bracket from somewhere else I would do it. I made it work but because the vibration transfers to the plywood base and the bracket didn't sit flat because of the plumbing, it is quite loud. Eventually I'll have to drain the spa and unhook the motor. Then I found a rubber motor mount that will probably work but I'll have to cut a hole in the plywood. Anyway, bottom line is that if it came without a bracket like the original, I would have no complaints, but I would expect these possible issues explained to me if the only spa pump available to me was one with a bracket.

Good pumps

Both pumps in my hot tub failed at almost the same time. Purchased 2 and the fit was perfect

Good Replacement Option

So far so good. Seem like a good replacement option. The wiring diagram instructions are really terrible. I had to call Spa Depot on what wire went where....There customer service is good so they helped me put the wires in the right spots. Other than the wiring instructions the motor and pump are working good.

Too easy

Spa Depot took my order over the phone and got me a more efficient setup than I had originally. Everything lined up perfectly. Thanks Spa Depot! I have just installed it so, too early for a parade but it sounds great and I'm a Electrial contractor so I believe that customers who had their motors overheat ""may"" have not wired it correctly:) Spa Depot got it to me fast. thanks again SD...

Excellent replacement!

Direct fit replacement for my spa. Excellent quality and fitment was drop in plug and play. I actually believe by my spa experience that this pump is superior than the original. It is definitely more quiet and feels like a stronger water flow than the one that was on it when it was new. Would buy it again in a heartbeat. As a last note the customer service at Spa Depot is second to none. A few pictures and they help you find exactly what you need.
