The QS Series Special Submersible Electric Pump is a high-performance water extraction solution specifically engineered for freshwater and seawater aquaculture. Featuring a sophisticated sand-proof, large-flow water system and a water-immersed motor, this series ensures that no oil leakage occurs even after mechanical failure, thereby preventing water pollution and protecting delicate aquatic ecosystems.
Designed for versatility and durability, the QS series is ideal for river water extraction and seawater oxygenation. With a broad operating range—flows from 100 to 1000m³/h, lifts from 3 to 100m, and power ratings from 3 to 100KW—it provides the scalability and reliability required for industrial-scale aquaculture and water management projects.

Frequently Asked Questions
No, the QS series is strictly a clean water pump. It is prohibited to use it for discharging sediments or muddy water during new well excavation to avoid premature wear and damage.
Filling the cavity with distilled or non-corrosive clean water is essential for lubricating the rubber bearings and cooling the motor during operation.
The system must be equipped with a distribution box providing short-circuit overload, phase loss, undervoltage, grounding, and idling protection.
The pump must be installed vertically. It should be placed in the center of the well pipe to prevent vibration and motor burnout caused by wall friction.
Generally, the bottom of the submersible pump should be no less than 3 meters from the bottom of the well to avoid sucking in mud or sand.
We recommend disassembly and inspection every year of operation, or every two years if the pump remains submerged without continuous operation.
