My pool pump motors hate me

[Straightleg]

Well on a new system now...Be nice to turn it off 12 hours or so a day. What do you think of my set up. Why am I going through so many motors. Does water get into those bearing that easy, or what ever is making me replace so often.

Thanks

My pump does not need the attention you describe. The guy I use to rebuild when I need it pointed out some rust on the bottom side of the motor housing due to a small leak. He said the rust deforms the housing and pushes the motor armature/ bearing plate out of line. It doesn't take much rust to do it because the tolerances are pretty close. Does your motor get wet? Can you see any rust?

Most pumps protect the bearings from moisture but that one looks like it might allow some water to get into the bearing area which really shortens the life of a pump. The matrix is a bit more shielded.

SO what kind of pump should I buy, and what size?
I have read some post to only filter my water 4 hours a day.

Just trying to get it right this time. Tired of buying pool motors

Thanks

There are a couple pump lines for AG pools that I would recommend:

Hayward Matrix
Pentair OptiFlo
Pentair Dynamo

3/4 HP to 1 HP two speeds

I think all are good pumps but I think the Matrix is a slightly better housing design that protects the bearings from moisture a bit better than the other two.

Thanks so much, really appreciate it.

Is there a link here to buy through amazon?

I bought this pump, through this site. 1 hp model.
I have 1 1/2 inch pipes.
How much water will it turn over on low per hour?
How much water will it turn over on high?

I looked in the directions, could not find GPH in the directions or on the pump


Thanks

It doesn't matter how much water will "turnover". Pump run time should be mostly independent of turnover or flow rate.

The reasons to run a pump and the time taken to do it:

Chlorination/circulation - Manual dosing ~ 30 min, SWGs require more time.

Skimming - Most skimming occurs in the first hour, after that only what falls in the pool.

Auto Cleaner - I find only 1 hour per day is required but you may not even have one so this is not even a consideration.

So mainly pump run time is just to get the debris out of the pool and not much more. Chlorination and circulation can happen pretty quickly.

I have a 20k pool and run for 1 hour on high and 3 hours on low speed per day but that is mainly because I have an SWG. In terms of turnover, that is less than a 1/2 turn per day.

You might want to read the pump run time study article in my sig.

I read this once when I first joined, and forgot you had this posted.

After reading your pump information, I set my timer to run 1 hour from 5-6am so I can clean the basket before I leave for work;
1 hour from 3-4 pm when I get home from work.
1 1/2 hours from 8-9:30 pm when I add my chemicals.
3 1/2 hours a day on low speed....


Keeping my numbers right, will see how that works out.



Thanks
