The Sobo WP-5200 Submersible Water Pump is a heavy-duty, energy-efficient utility pump designed for high-capacity water circulation. Operating at 75W, it is engineered to deliver a maximum flow rate of 3,500 litres per hour (L/H) with a maximum vertical lift head of 3 metres. This makes it highly versatile for medium-to-large setups, including garden ponds, multi-tier fountains, sump filter systems, and both freshwater and marine aquariums.

Key Specifications:

• Flow Rate: 3,500 L/H maximum output.
• Maximum Head Height: 3.0 metres (Note: Flow rate decreases to zero as it approaches this height).
• Power Consumption: 75 Watts.
• Voltage Compatibility: AC 220–240V (50/60Hz).
• Power Cord Length: 270 cm to 300 cm.
• Dimensions: Approximately 18 x 14 x 10 cm.

Core Features & Engineering:

• Durable Ceramic Shaft: Fitted with a wearproof, waterproof ceramic shaft core instead of standard metal, preventing rust and ensuring longevity in salty marine environments.
• Dual-Environment Use: 100% safe for both freshwater and saltwater setups.
• Whisper-Quiet Operation: Utilises a fully encapsulated motor housing that dampens vibration, delivering ultra-quiet performance even under heavy loads.
• Flexible Submerged Configuration: Packaged with heavy-duty suction cups for stable placement against tank walls or sump floors, preventing shifting from torque.
• Amphibious Capability: Certain model configurations are built as “In/Out” designs, allowing the unit to run inline externally or fully submerged.

Performance Considerations:

When planning plumbing for the WP-5200, factor in that the 3-metre max head height represents the point of total flow cutoff. For optimal performance in fountains or water features, keep your active lifting height well below 2.5 metres to maintain a strong volumetric flow. Tubing diameters, elbow joints, and inline friction will also reduce the ultimate output.
