AquaKing Q4003 Submersible Pump — 7,000 L/hr

AquaKing Q4003 Submersible Pump — 7,000 L/hr

A mid-range AquaKing submersible pump rated at up to 7,000 litres per hour, with a 25/30mm side connection for direct hose attachment. Sits between the smaller Newa pumps and the large-volume Q5503 — the right size for serious home reservoirs, mid-scale circulation, and general grow-room pumping duties.

Why growers choose the AquaKing Q4003:

• 7,000 L/hr max flow — handles larger home reservoirs and small commercial setups comfortably
• 25/30mm side connection — direct hose fitting, no adaptors needed for larger irrigation pipework
• Submersible design — quiet operation, no priming required when fully submerged
• Versatile applications — reservoir emptying, flood clearance, rain barrel pumping, pond management
• Reliable AquaKing build — Dutch horticultural brand known for pump longevity
• Between Newa and Q5503 — right-sized for most serious home grows without commercial overkill

Who it's not for:

For small home reservoirs (under 100L), a Newa Jet NJ 2300 is more appropriate. For commercial-scale grows with 500L+ reservoirs, step up to the Q5503. Must run submerged — never dry-run.
