High Performance Pumps!The Aquamax SF filter pumps represent the evolution of the time-tested Aquamax series. The addition of a dedicated, flow-controllable intake for skimmers or the included satellite filter makes the Aquamax SF the most advanced and versatile filter pumps on the market. A single Aquamax SF pump can serve as the heart of a multi-level pond filtration system. With a skimmer connected, the Aquamax SF removes debris and leaves from the pond surface while doing regular duty as a deep water filter feeding pump. The result is exceptionally clear water at a low operating cost.
