I have a 30k gallon inground pool with Hayward 1HP superpump. With a big help from Mark (mas985) the flow rate was estimated at 67-71 GPM, which gives me a 7-8 hour turnover time.
I was thinking about what kind pump to get in case I need to replace my current one. I have no water features, no spa, no solar heater, nor I run manual vacuum. In other words my pump is only for filtering and water circulation.
I would want my new pump to be efficient and cost effective. I know that 2 speed pumps have a lower speed and pumping twice as slow saves 4 times the energy. I don’t really want a 2 speed pump, or variable speed pump, since in my simple thinking I only need a slow speed mode and don’t want to pay for option of having higher speed(s) that I don’t need.
So is there such a thing as a “slow†pump? Or can the same effect be achieved by undersizing the pump and running maybe 1/2HP pump for twice as long for my size of the pool?
