PerformancePro Artesian Pro High Flow

The PerformancePro Artesian Pro High Flow is built for large koi ponds and water features that need serious volume. Running at 3450 RPM with 3-inch ports, this pump delivers 8,640 to 19,740 GPH — making it one of the highest-flow external pond pumps available. When your pond demands rapid turnover or your filtration system needs heavy throughput, the Artesian Pro High Flow is engineered to deliver.

Seven models range from 1/2 HP to 5 HP, covering everything from mid-size koi ponds to professional-scale installations. Smaller models offer dual 115V/230V wiring flexibility, while the larger units (2 HP and up) run on 230V for maximum efficiency at higher horsepower. The 3-inch ports keep friction loss low even at high flow rates, ensuring the GPH you read on the spec sheet is close to what actually reaches your pond.

Head pressure ranges from 39 to 68 feet across the lineup, so you get strong performance even with moderate plumbing runs and elevation changes. If your setup calls for high volume — think ponds over 8,000 gallons, multi-filter arrays, or large waterfall features — the Artesian Pro High Flow has the muscle to keep everything moving.
