When Looking for a new hot tub/ spa pump you will need to identify the correct model using the labels on the pump motor.
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.
To identify the correct replacement hot tub pump you will need is easy. if you can provide us with the following information we can can help to process your order quickly and efficiently.
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.
Measure the wet end to establish what size frame you are currently using in your hot tub. You can find the existing frame size on the label on your hot tub pump motor. See #4 on the label below - 
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

The second label on the hot tub pump will be the manufacturer's ID label. This label will contain the part number – see #1 on the label below. The part number will tell us whether the pump has an intake of 2 1/2" or 2".
