AquaKing Q5503 Submersible Pump — 11,000 L/hr

AquaKing Q5503 Submersible Pump — 11,000 L/hr

A serious-capacity submersible pump rated at up to 11,000 litres per hour — built to move large volumes of water in flooding, reservoir emptying, or commercial-scale hydroponic circulation. Side-connection fitting takes 20mm or 25mm hose directly.

Why growers choose the AquaKing Q5503:

• 11,000 L/hr maximum flow rate — moves serious volumes fast, handles large reservoirs or flooding scenarios
• 20/25mm side connection — direct hose fitting, no adaptors needed for standard irrigation pipe
• Submersible design — operates fully underwater, runs quietly with no dry-running risk
• Versatile applications — commercial reservoir management, flood clearance, pond emptying, swimming pool draining
• Robust AquaKing build — Dutch horticultural brand known for long pump lifespans in commercial settings
• Bulk dewatering capability — not just a reservoir pump, handles real emergencies too

Who it's not for:

Overkill for small home hydroponic reservoirs — a 1,000-4,000 L/hr pump will do the job for most domestic setups. Must run submerged — never dry-run, it'll damage the pump. For filtered-water applications (drinking, aquaponics with live fish), check the pump's compatibility spec first.
