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.
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
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.
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
Ideal for koi ponds and ponds with large fish populations
Adjustable flow allows precise matching to filters and waterfalls
Suitable for internal or external (dry or wet) installation
Excellent choice for custom pond builds and flexible layouts
Supplied with hosetails for standard hose connections
Includes BSP threaded outlet for hard pipe installations
Flow rates from 2,500 LPH to 20,000 LPH
Handles solids up to 5mm
Energy efficient and cost-effective to run
Adjustable flow rate
Suitable for dry or wet installation
Easy to maintain
4 models available
Internal use: Simply connect the 10m power cable and position the pump in the pond, filter, or fountain
External use: Pump must be primed before operation
The pump features a large pre-filter strainer cage for easy maintenance:
Remove the strainer basket
Clean using a bucket of pond water
Occasionally clean the impeller while protecting the ceramic shaft
