Variable Speed Pool Pump Flow Rate

Another pump affinity law teaches that when the pump speed is reduced by half the flow rate is only reduced by half.

Variable speed pool pump flow rate.

Eight programmable speed or flow settings and built in timer. Variable speed pool pumps. With this feature you can use less energy when high speed circulation is not required. When you run the pump at lower speeds that means you re using less kw or energy from your power company.

We carry large items like heaters pool covers spa covers and portable spas as well as small and hard to find items like fittings. However you will not get maximum efficiency from a dual speed pump because they cannot be fine tuned to specific flow rates. 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. It is an exceptional pool pump for both above ground and on ground pools.

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. 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. 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. Even though the ecostar and the tristar 2 7 hp for example are rated as twice as powerful as the maxflo and super pump vs models the actual flow rate is only at most 23 gpm different.

It s like having cruise control for your pump. Using a variable speed pump can cut associated energy costs up to 90. It can be used at 3 450 or 1 725 revolutions per minute thus allowing you to throttle the pump s flow.
