Variable speed pool pump flow rate.
The hayward sp15932s powerflo is one of the best dual speed pool pumps available.
Eight programmable speed or flow settings and built in timer.
When you run the pump at lower speeds that means you re using less kw or energy from your power company.
A variable speed pump allows you to lower the motor s rpms to the minimum speed needed to turn the water over or to maintain your pool equipment.
Using a variable speed pump can cut associated energy costs up to 90.
By far the best option when it comes to pool pumps variable speed pumps are much quieter than single or dual speed pumps and allow for a full range of speeds to easily fine tune flow rates.
However you will not get maximum efficiency from a dual speed pump because they cannot be fine tuned to specific flow rates.
Variable speed pool pumps.
But the flow rate at the slower speed is lower than at the higher speed so the pool must be operated for a longer period of time to process the same volume of water through the filter.
It can be used at 3 450 or 1 725 revolutions per minute thus allowing you to throttle the pump s flow.
With this feature you can use less energy when high speed circulation is not required.
It s like having cruise control for your pump.
This side by side comparison of hayward variable speed pump flow rates shows just how similar minimally different the flow rates are in these pumps.
Another pump affinity law teaches that when the pump speed is reduced by half the flow rate is only reduced by half.
It is an exceptional pool pump for both above ground and on ground pools.
