need pump motor advice

[Poconos]

Two summers ago I bought a 1/2 HP single speed from this place. Price was good and delivery in a couple days. They had quite a selection then and probably still do and it's probably a good place to start your search.

Thanks for the advice.

There used to be a motor repair shop in town, but no longer.

So it's a new pump for me. According to www.inyopools.com dual speed pumps and motors seem to go for around $400. A new dual speed motor only is around $250. Yet there are many pump motor combinations for around $200.




Do I need to find out the flow rate? I thought I read somewhere that flow rate was more important the horsepower. That I should be turning over the entire 12,000 gallon pool in so many hours/day/etc.


Decisions, decisions.....

When replacing a motor in a pump, you need to match the braking horsepower of the motor to the existing motor.

Brake horse power= Label horsepower * Service Factor

If your old pump does not have a service factor listed on the motor, then assume it is 1.0.

Picking a motor which is slightly larger than your existing motor is ok but you don't want to undersize the motor as it will quickly burn out. Oversizing the motor too much is a waste of energy so try to get as close as possible. Most pumps today have direct motor replacements so it shouldn't be too hard to find one.
