The PerformancePro Artesian 2 Low RPM is an energy-efficient external pond pump designed for koi ponds and water features that use 2-inch plumbing. Running at a quiet 1725 RPM with a TEFC motor, this pump delivers 3,900 to 7,560 GPH while drawing just 200 to 630 watts — making it one of the most efficient pumps available for 2-inch pipe installations. Five models span 1/8 HP to 1/2 HP, giving you precise control over how much flow and energy your system uses. The low RPM design runs cooler and quieter than high-speed alternatives, which means less wear on the motor and a longer service life. Dual 115V/230V capability across all models lets you choose the electrical setup that works best for your situation. The Artesian 2 Low RPM is an excellent match for small to mid-size koi ponds running 2-inch plumbing to bead filters, UV clarifiers, or gravity-return systems. With up to 26 feet of head pressure and wattage that won't spike your electric bill, it's a smart pick for hobbyists who value efficiency and quiet operation over raw power.
