    Pool Pump Died. Not sure if I should go single speed or dual speed

    I have a 35k in-ground pool.

    With DE Nautilus Filter 36SQFT

    I purchased a Liquidator that I am planning on adding this year.

    I had planned on installing a timer to run with the liquidator that would run for 8ish hours or whatever was needed to turn the pool over once per 24hours.

    I also have a home brewed wood fired heater, double barrel stove. I have a valve that I close to shunt some of the water through the heater.

    The old pump was only 6 years old, I think a bearing went in it. I could hear a whirring sound over the last 2 seasons that kept getting worse. When I hooked it up this year it just stalled. I took the pump apart looking for obstructions. When the pump was disconnected it would work but get extremely hot. Another reason I am assuming that it is a bearing.

    The old pump was a hayward 1hp .75Kw single speed. I only have 120AC going to the pump.

    My electric rate is 5.88 cents per KWH. no peak / off peak that I can tell.
    There is also a distribution charge of 5.1 cents per KWH on top of that.

    Please let me know if there is any other information that would help.

    With only 120 going to the pump im not sure if I can even go dual speed. I cant seem to find any pumps that support that. I assumed it would be like a ceiling fan with a capacitor for switching Speeds.

    Also i have 1.5" pipes.

    There is a very limited supply of it will speed pump that will run on 120 volts. The only one I can think of off the top of my head is the three quarter horsepower WhisperFlo I think.

    Thank you.

    I was not able to find much and since I already have all the fittings and plumbing sized for hayward I am just going to stick with hayward and get a 1.5hp super pump. (I figure upgrading from a 1hp to 1.5hp should help any wear issues)

    Hayward SP2610X15 Super Pump 1.5-HP Max-Rated Single-Speed Pool Pump from amazon is $375. I can get up and running in a few days.

    Going to a larger pump will not change wear issues. It is just going to cost you more in electricity to run.

    I would not call spending more money on a pump that is going to cost more to run an upgrade

    By the way you like the only need to replace the motor the wet end of the pump is probably fine
