Does the cord come with the pump I just bought and if not can you buy it separately ? The cord on the old pump is pretty old and should be replaced too.

I have a pump PF-40-2N22C dated 2012, Does the motor have a start capacitor ??? there is a run capacitor on top of the motor. I see the new replacement PF-30-2N22C have combination start/run capacitor.

A  Answered on 4/10/2020 by InyoPools Product Specialist Matt S.

To determine if a motor has a capacitor, we would need the part, model, or catalog number from your current motor's label. Or, you can inspect the motor yourself; look for the capacitor bump on the motor's topside, or remove the endcap where the terminal leads are located.

The BN-62 is a 48 frame motor. Use part # 34-270-3566 for a wet end with 2" x 2", & use 34-270-3568 for a wet end that has 2-1/2" x 2"

What is the distance from your pump to your spa so I can calculate the flow rate.
