SOBO High-Performance Aquarium and Pond Pump

SOBO High-Performance Aquarium and Pond Pump

SOBO High-Performance Aquarium and Pond Pump is a heavy-duty water pump from the WP-DW Series, built for large koi ponds, ambitious waterfalls and big filtration systems. It suits freshwater and marine setups and can run fully submerged or externally (inline). Pond keepers and large-system owners who need serious water movement without an industrial power bill will find it a good fit.

These are not standard aquarium pumps. The WP-DW Series covers flow rates from 20,000 to 48,000 L/H, and each step up the range adds both flow (litres per hour) and head height (lifting power). Frequency conversion technology keeps the pump efficient, and pond enthusiasts favour the range for its "set it and forget it" reliability.

Key Benefits

• Ultra-high output for large volumes of water, suited to koi ponds, garden waterfalls and commercial-sized aquariums.
• Advanced frequency conversion technology delivers strong flow with minimal energy consumption.
• A wear-resistant ceramic shaft resists corrosion and extends motor life, even in saltwater setups.
• Amphibious design: run it fully submerged or externally (inline) to match your plumbing layout.
• Built-in thermal protection shuts the motor down if it detects overheating or dry-running, helping prevent permanent damage.
• Consistent, high-pressure flow with surprisingly quiet operation, whether it runs a 24/7 filtration system or a decorative waterfall.

How to Use

• Choose the model that matches your flow and lift requirements, then fit the nozzle adapter that suits your hose or pipework.
• Install the pump fully submerged, or externally (inline), depending on your plumbing configuration.
• Keep the intake cage clear of large debris.
• Clean the impeller every 3–6 months to help maximise the pump's lifespan.

• Large ponds and koi ponds
• Garden waterfalls, large water features and fountains

Frequently Asked Questions

Can this pump run inside and outside the water?
Yes. It has an amphibious design, so it can run fully submerged or externally (inline), depending on your plumbing configuration.

Is it suitable for saltwater and marine systems?
Yes. The WP-DW Series is built for both freshwater and marine environments. Its wear-resistant ceramic shaft prevents corrosion, even in saltwater setups.

What happens if the pump overheats or runs dry?
Built-in thermal protection automatically shuts the motor down if it detects overheating or dry-running, which helps prevent permanent damage.

Which model should I choose for a koi pond?
The WP-30000DW (30,000 L/H) is suggested for professional koi ponds. The WP-20000DW suits large ponds and small waterfalls, and the WP-25000DW suits mid-sized pond filtration. Choose by the flow rate and head height your setup needs.

Do all models have the same cable length and adapters?
No. The 20000, 25000 and 30000 models have an approx. 4 m (13 ft) cable, while the 38000 and 48000 models have approx. 7 m (23 ft). Adapters also differ between the two groups, as listed under Specifications.
