| Both Performence Pro & Sequence are quality pumps and I recommend either. Unless you get an exceptional deal, buy it locally. If something goes wrong, help is right down the block.
Variable pumps have a purpose. They vary speed rather than valving off flow to adjust pumping rate. In constantly varying loads they will be more efficient. In our relatively constant loading purchasing the right low speed pump will actually be much more efficient.
If you need two flows, consider two pumps in parallel. When high flow is needed both can be run together. |
