Dual Speed Pump Question

[SLS]

I am thinking about replacing my broken pump with a 1HP dual speed Hayward Super Pump. Does anyone know if it will be able to push (not pull) the water up 8' in low speed? Can you still have the filter in the filter mode on low speed? Will my in-line automatic puck chlorinator still work on low speed?

I run my pump 24/7 from the time I open in the spring to the time I close it in the fall because I am gone alot. It just keeps it cleaner that way. I am hoping low speed will help the electric bill.

Also, will I have any trouble with the 1hp super pump being too big for (1) 1 1/2" dia. skimmer intake and (1) 1 1/2" dia. return? I plan on remodeling my pool next year and I will be installing another skimmer and return so I like to get a big enough filter and pump now. My pool is a 20 x 40 / 32,000 gallon vinyl inground pool.

BTW, after the remodel I will not have to push the water up 8'.....another story!!

Yes...it is a closed loop not open to atmospheric pressure so you could put the pump 80' on the top or bottom of the loop...no difference.

1. Yes 2. Slowly...although most of us here don't like in-line chlorinators

Wow! That's not nearly enough pipe, skimmers, or returns for that size pool. I see why you're remodeling.

I'd probably get the same pump and live with it for a year, tho. The problem you may have is not being able to stay on "low" 24/7 because you won't turn your water as often as you should.

Thanks for the response!!

The pool actually stays clear but it will be nice to have another skimmer and return!!

Pool pumps, or pumps in general, can't pull or push an unlimited amount of water.
The Hayward Super Pump 1HP can prime itself from 8' above water or push water 65' up. On low speed the pump could push approximately 15-20 feet in the air.
In the middle of this page : http://haywardcanada.com/products/pid_10.html , it says, "Self-priming (suction lift up to 8’ above water level)"
And on the same page it says that the pump has 0 GPM flow above 65ft of head.
You will be able to run your sand filter, but probably won't be able to backwash properly.
You'll probably get approximately 30 GPM on Low speed, which will turn over 43,200 gallons of water per day.

One thing to remember is that once the pump is primed, static head is no longer an issue. Only dynamic head will determine the flow. After prime, the 8 ft rise is balanced by an 8' drop on the other side of the pump.

If you have a 2 speed controller, then normally it sets the pump to run at full speed at start up and then after 3 min, it drops the speed to low speed.

I think you'll love the 2 speed 1 hp SuperPump--I do. I have a skimmer and low drain, a return and a solar deck, about 20,000 gals. All 1.5" piping. I run on low all the time with no problem--be sure to have at least a 200# sand filter--the Hayward t210 is a good match.

Just flip to full speed to backwash or vacuum.

It will take almost twice as long to turn over your water as it does at high speed--and will cost 1/3 as much per turnover. Also low is SO quiet you can barely hear it.
