When you look at the hot tub pump you will notice it has two main components, the wet end and the dry end (Motor). The wet end contains the impeller which moves the water through the hot tub plumbing and jets and the dry end which turns the impeller.

Frame size :  When looking at the your hot tub pump, if you have space in your hot tub for a 56 frame unit then. it is recommended to choose this option over a 48 frame unit. This is because it is more reliable in the long term and will offer better durability and they are kept slightly cooler when in use.

Does your hot tub have a one- or two-speed motor? If your motor has one RPM number then it will be one speed. If it has two RPM numbers then it will be a two-speed motor. It is advisable to make a note of these numbers they will be separated by a "/" for two-speed motors and are sometimes referred to as GIRI numbers. 
Horsepower, if shown, is commonly referred to as HP, can be useful. We cross check this information with the motor companies by looking at the amp range. This will give our team a good idea of a motor's horsepower range as some companies inflate the horsepower.
Below are the high-speed amps. See #3 on label below.
7–8 amps = 1.5 HP
9–10 amps = 2.0 HP
10–11 amps = 2.5 HP
11–12 amps = 3.0 HP
14–15 amps = 4.0 HP
