The QS series water-filled submersible pump represents a high-efficiency advancement in irrigation and drainage machinery. Engineered with a vertical radial positive and negative guide vane design, these pumps offer a compact footprint and lightweight construction without compromising on power. With a versatile flow range of 5-50m³/h and an impressive lift capacity reaching up to 800m, the QS series is the ideal solution for challenging water extraction environments requiring high vertical transport.
Designed for reliability and ease of operation, the QS series features a water-immersed three-phase asynchronous motor. This sophisticated design utilizes the surrounding water for both cooling and bearing lubrication, significantly extending the service life of the equipment. From agricultural irrigation to industrial water supply, the QS series combines computer-aided CAD design with high-performance insulation materials to ensure stable operation under rigorous submersible conditions.

Frequently Asked Questions
No, the QS series is specifically designed for clean water. Pumping mud, sediment, or using it to wash new wells is strictly prohibited as it will cause premature damage to the impellers and bearings.
The motor uses a water-filled wet structure for cooling and lubrication of the rubber bearings. Operating the pump without filling the cavity will lead to overheating and immediate motor failure.
The insertion depth should not exceed 70 meters, and there must be a minimum distance of 3 meters between the bottom of the pump and the bottom of the well to ensure adequate water intake.
In freezing temperatures, you must drain all water from the motor cavity to prevent ice damage. Store the unit indoors in a non-corrosive environment below 40°C.
The pump requires a 3-phase AC 380V/50Hz supply. It must be equipped with waterproof cables and an external protection box featuring overload, phase, and grounding protection.
Common wear parts include the impeller, shaft sleeve, rubber shaft sleeve, and sealing rings. These should be inspected and replaced annually or every two years depending on usage.
