Description Hsbao Variable Flow Pond Pump – Energy Efficient DC Pump Range The Hsbao Variable Flow Pond Pump range consists of highly versatile, energy-efficient DC pond pumps designed for a wide variety of pond, filtration, and waterfall applications. With models ranging from 2500 LPH to 20,000 LPH, these pumps are suitable for everything from smaller garden ponds to large koi ponds with heavy fish loads. All models are DC powered, making them quieter, more efficient, and cheaper to run than traditional AC pond pumps. Available Models & Flow Control SWD-2500 (23W) – Max flow 2,500 LPH SWD-6000 (45W) – Max flow 6,000 LPH SWD-12000 (85W) – Max flow 12,000 LPH SWD-20000 (150W) – Max flow 20,000 LPH Variable Flow Control SWD-2500 / SWD-6000 / SWD-12000: Adjustable from 30% to 100% SWD-20000: Fully adjustable from 1% to 100% 100% = maximum pump flow 1% = 0.01 × maximum flow Reducing the flow rate also reduces electricity consumption, helping lower running costs. Why Choose a DC Pond Pump? DC pond pumps offer several advantages over AC pumps: Higher energy efficiency Quieter operation Longer lifespan Safer low-voltage operation Higher RPM allows greater torque and pressure Provides a higher maximum head compared to AC pumps of similar size Why Buy the Hsbao Variable Flow Pump?
