Spa pump sizing

[Tnafranklin]

I am needing to replace my spa pump and I am looking for some guidance. The motor is 3 h/p with 13.3 amp rating. I am having a hard time finding one with these amp specs. Can I go down in amps or is this not advised Any help or suggestions would be greatly appreciated!

Welcome to TFP.

DOE regulations have banned the sale of most single speed pumps of 1HP or more. You need to get a VS pump for your spa.

If that pump is powering your spa jets you probably want a pump around 3HP.

Do you have automation?

How is the pump controlled?

What is the rest of your pool equipment?

It is a 2 stage pump on a stand alone hot tub. I can find 3 h/p pumps but I am concerned about the difference in amps. Or I should say I don’t know enough to know if amps make a difference. For instance I found a 3 h/p pump with 10 amps but I am not sure if this makes a difference.

Ah, @RDspaguy should point you in the right direction when he wanders by.

I don’t think a small difference in amps make a difference if it is rated at 3HP.

What model spa is it?

It’s a jewel plus spa. It came with the house when we bought it a few years ago so it’s definitely older. I’ve kind of been learning about my spa and salt generator pool as things come up for repair. I appreciate this forum and all of the help offered here!

This shows only one speed?

DOE regulations have banned the sale of most single speed pumps of 1HP or more. You need to get a VS pump for your spa.

The following pumps are exempt from the DPPP efficiency requirements:

• Three-phase pumps
• electric spa (hot tub) pumps
• pumps greater than 2.5 HHP (approximately 5 total horsepower [THP])

Yeah, I thought we were discussing an inground spa connected to a pool.

There is a sticker on the top of the motor that says 2 speed and there is definitely 2 speed difference between when the heater is circulating and the jets are on.
