AquaKing Submersible Water Pumps - Reliable Reservoir Feeding at Any Scale
Best for: Growers who need a dependable submersible pump to feed a reservoir, drip system or DWC setup, from a small tent up to a multi-tank commercial room.
Our thoughts
A pump is one of those things you don't want to think about twice a week, and AquaKing's range is built exactly for that - fit it, run it, forget it. We stock the full spread from the small Q2007 right up to the Q5503, so whether you're feeding one tent or a whole row of tables you can size the pump to the job instead of overbuying. Nothing flashy here, just solid, submersible workhorses at a price that makes sense.
AquaKing Submersible Water Pumps are fully submersible pumps designed to sit inside a reservoir or tank and push nutrient solution or water out to your irrigation system, drip line or recirculating hydro setup. The range runs from the Q2007 (3600 litres/hour, 200W) through the Q2503 (5000 litres/hour, 250W) and Q4003 (7000 litres/hour, 400W) up to the higher-output Q50011 (10000 litres/hour, 500W) and the flagship Q5503 (11000 litres/hour). The smaller models are rated to an immersion depth of around 5 metres, with the mid and larger models rated to roughly 7 metres.
Each pump is built with a sealed, epoxy-potted motor so it can run fully underwater without risk to the electrics, and they're designed for continuous duty rather than occasional use, so they can be left running in a reservoir for extended periods without overheating.
How it compares
AquaKing sits in the same value bracket as the other well-known submersible pump brands used across UK hydro shops.
- Hailea's T-series submersible pumps cover a similar output range and are known for reliability, but AquaKing's range gives you finer steps between flow rates so it's easier to match the pump to the tank size.
- EcoPlus and Active Aqua pumps (common in US-style hydro setups) cover a similar GPH range but are less commonly stocked in UK grow shops, which can mean longer waits on spares.
- Cheaper unbranded pumps at this price point often cut corners on motor sealing and continuous-duty rating; AquaKing's are built to run 24/7 in a reservoir without issue.
You're paying for a pump that's sized correctly for the job and built to run non-stop, not for a brand name.
Usage guidance
Getting the sizing and setup right makes a real difference to reliability.
Sizing the pump
Match flow rate to your system: a single small drip or DWC setup is usually well served by the Q2007 or Q2503, while multi-tank rooms or systems feeding several drippers or a chiller loop will want the Q4003 or above.
Installation
Stand the pump on a small platform or the reservoir floor away from sediment, keep the intake clear of debris, and always submerge it fully before switching on - these pumps are not designed to run dry.
Maintenance
Rinse the impeller housing periodically to clear any mineral buildup from nutrient solution, especially in hard water areas, to keep flow rate consistent over time.

Who this is for
- Growers setting up a reservoir-fed drip or DWC system who need a pump sized to their tank
- Anyone replacing a failed pump and wanting a known-reliable submersible option
- Multi-tank or commercial growers who need higher-output models for larger volumes
- Budget-conscious growers who want a proper pump without paying premium-brand prices
Best suited to anyone who wants to size a pump correctly to their system rather than guessing.
Our take
This is straightforward kit that does one job well: move water reliably, day after day, without drawing attention to itself. Having the full range on one listing means you can size up or down without hunting through separate product pages.
One we sell a lot of for new growers setting up their first reservoir-fed system - pick the flow rate that matches your setup and it'll get on with the job.
