AquaKing Q4003 Submersible Water Pump - 7,000L/h
Please sign in to see pricing

£42.52
Unit price perEstimated delivery between November 01 and November 03.
The AquaKing Q4003 is a submersible water pump rated at up to 7,000 litres per hour, with a 400W motor and a maximum head of approximately 8 metres.
Designed for moving water in suitable reservoirs, drainage and horticultural irrigation arrangements, the pump provides a practical way to transfer water between tanks or supply compatible distribution systems.
This model prioritises dependable bulk water movement. The published maximum flow is a free-flow rating; actual delivery decreases as pumping height, hose length and system resistance increase.
The supplied Shopify SKU represents one pump, not a case. An adaptor is listed as included in the existing product export. The trade case contains 6 pumps, for logistics only.
Why choose the AquaKing Q4003?
- 7,000L/h published maximum flow
- 400W motor
- Submersible design for suitable water-transfer duties
- Approx. 8m maximum head
- Practical for appropriate reservoirs and irrigation installations
- One pump per Shopify SKU; trade case is not the selling unit
- Adaptor included according to the existing catalogue
Understanding flow rate and head pressure
The stated 7,000L/h is the manufacturer’s maximum rated capacity under favourable conditions. Maximum head of 8m is a separate performance limit, not a promise that the pump delivers its full rated flow at that height. As lift and pipe friction increase, usable flow falls. Select pipework, fittings and any emitters against the actual pump curve and the installation requirements.
Suitable horticultural applications
This pump can be considered for moving water between suitable tanks, reservoir circulation, drainage or irrigation feed duties where the required head and flow are within its operating range. For pressure-sensitive drip emitters or long pipe runs, check working pressure at the emitters rather than selecting on litres per hour alone.
Installation and connection guidance
The manufacturer lists the connection arrangement as 25/30mm hose connection; 1-inch external thread. Confirm the supplied adaptor, hose size and thread compatibility before installation. Place the pump on a stable surface, keep the intake clear of debris and follow the product instructions for permitted water quality, immersion depth and electrical safety. Do not run dry unless the model documentation expressly allows it.
Choosing between AquaKing pump models
The Q2007 and Q2503 suit lower-flow duties, while the Q4003, Q50011 and Q5503 offer progressively higher nominal flow. The Q800103 differs by providing substantially greater maximum head. A higher L/h rating does not necessarily mean a pump is better for a pressurised irrigation network.
Maintenance and reliable operation
Inspect the intake regularly and remove accumulated debris as directed by the manufacturer. Check hoses, connections and cable condition before use. Disconnect power before cleaning or maintenance, and follow the supplied manual for permitted liquids and operating conditions.
Trade packing and ordering
Selling unit: one pump. Case quantity: 6 pumps (logistics only). Pallet quantities have not been assumed. Order quantities on the website refer to individual pumps, not full cases.
