Sequence Power 4000 Pump Series

The Sequence Power 4000 Series is built for the largest and most demanding koi pond systems. Equipped with a 3.0 HP motor, 2-inch ports, and head pressure exceeding 80 feet, this pump delivers 11,200 to 13,200 GPH — the kind of performance needed for commercial-grade filtration, multi-stage filter systems, or ponds with extreme elevation changes.

Where the Power 4000 really shines is in setups with long pipe runs, multiple filters in series, or tall waterfall features that would choke a standard pump. The 2-inch ports reduce friction loss, and the high-head impeller design keeps water flowing strong even under heavy back-pressure. Both models run on 230V and require dedicated electrical wiring.

If you're building or upgrading a large koi pond — 10,000 gallons and up — and your plumbing demands serious head pressure, the Power 4000 delivers. Backed by Sequence's 5-year warranty, this is professional-grade pond pumping for hobbyists and pond builders who refuse to compromise.
