AquaKing Q5503 11000L/h

High-Flow Circulation for Large Reservoirs and NFT Runs

The AquaKing Q5503 11000L/h is a heavy-duty submersible water pump built for high-flow hydroponic systems, irrigation networks and large reservoirs. Delivering a maximum flow of 11,000 litres per hour and a 8.5m head height, it keeps nutrient solution moving reliably through NFT systems, drip irrigation and flood-and-drain setups. Its powerful 550W motor and durable build suit continuous operation where a weaker pump would leave part of the system short of solution.

Key Benefits

• 11,000 L/h maximum flow for high-demand hydroponic and irrigation systems
• 8.5m maximum head height for elevated systems and longer pipe runs
• 550W motor built for continuous duty
• 25mm and 30mm hose fittings plus a 1" male threaded connection
• Handles particles up to 5mm without clogging
• Durable construction for grow tents, grow rooms and commercial setups

Uneven feeding and weak flow in a bigger system?

Once a system grows past a few plants, an undersized pump shows up fast as uneven nutrient distribution, low oxygen at the far end of an NFT channel and patchy growth across the crop. The Q5503's flow rate and head height push nutrient solution consistently around larger systems, keeping delivery even from the first plant to the last, supporting healthy root development and steady uptake while reducing the risk of stagnant water.

How to Use

1. Fully submerge the pump in a clean water or nutrient reservoir.
2. Connect the appropriate hose or fitting securely to the outlet.
3. Plug the pump into a suitable mains power supply.
4. Switch on and check water is flowing freely through the system.
5. Inspect regularly and clean the intake to clear debris or mineral deposits.
6. Never run the pump dry, as this will permanently damage the motor.
