The AQUAKING Q4003 is a powerful submersible water pump with a capacity of 7000 L/H, designed for indoor growing . It performs well in automatic irrigation systems , spray nozzles, and hydroponic recirculation circuits, consuming only 80 W. Made with durable materials, it delivers a stable flow rate for efficient indoor watering .

The AquaKing Q4003 7000 L/H Water Pump is designed to move large volumes of water with stability and low energy consumption. Its plastic body is corrosion-resistant , and the magnetic rotor incorporates stainless steel that will not deform with continuous use.
This submersible pump boasts a flow rate of 7000 L/h and a working depth of up to 5 m , making it ideal for irrigation tanks, raised beds, and hydroponic recirculation systems. It operates at 80 W , maintaining an outstanding balance between performance and energy efficiency.
Perfect for integration into an online grow shop and demanding indoor growing projects, it allows feeding irrigation rings, manual lances and collectors, providing uniformity in the return and distribution of the nutrient water.
The airtight design helps reduce vibrations and maintain a contained noise level, promoting a comfortable working environment in indoor spaces.
Compatibility with standard tanks and submerged installation simplify maintenance, while the robust construction withstands the intensive on/off cycles typical of an automated irrigation system .
In short, a reliable component within the irrigation accessories of any domestic or professional hydroponics project that requires sustained flow and sufficient pressure to water indoor crops without interruptions.
In indoor growing environments, this pump ensures constant circulation of nutrient solution, prevents stagnant areas in reservoirs, and improves oxygenation by facilitating dynamic return. The Q4003 performs well in flood irrigation systems, hydroponic recirculation systems, and reservoirs with irrigation lances, promoting EC and pH uniformity throughout the entire system.
It is used to pump nutrient-rich water from the reservoir to drippers, rings, or lances, and to maintain continuous recirculation in closed circuits. The 7000 L/h flow rate allows for feeding multiple irrigation points simultaneously and sustaining rapid returns, optimizing nutrient rotation in hydroponic systems. It also assists in transferring, emptying, and cleaning deep reservoirs up to 5 m .
It works perfectly with irrigation accessories such as hoses, valves, distributors, and pre-filters that trap particles. In a smart irrigation system , it can work in conjunction with timers and controllers to program precise cycles. Adding a pre-filter and a check valve improves durability and prevents unwanted backflow into the tank.
1) Place the submersible pump in the tank, ensuring a clean and stable base.
2) Connect the outlet to the main irrigation line and check for leaks in a first test with water.
3) Purge the circuit to expel air from hoses and fittings.
4) Schedule irrigation times according to the needs of the crop, verifying pressure and flow rate at each emitter.
5) Perform periodic cleaning of the stainless steel magnetic rotor and pre-filter to maintain optimal performance.
