The Keda QS Graphite-Sleeve Deep-Well Pump is a high-performance unit designed specifically for water extraction from deep wells, manufactured using advanced technology and premium materials.
1. High-Efficiency and Energy-Saving Design
Utilizes an optimized hydraulic model and a graphite-sleeve structure to significantly enhance pump efficiency and reduce energy consumption. The centrifugal impeller design, combined with a multi-stage series configuration, achieves high lift—up to 550 meters—meeting the demands of deep-well pumping.
2. Corrosion and Wear Resistance
● Graphite-Sleeve Technology: Key components feature high-strength graphite sleeves, offering excellent corrosion resistance and suitability for water with high sand content or acidic/alkaline properties.
3. Compact Structure and Stability
● Integrated motor-pump design ensures a compact size and light weight, facilitating down-hole installation and maintenance.
● Equipped with water-lubricated bearings and a pressure-regulating diaphragm to ensure smooth operation and minimize mechanical wear.
4. Broad Applicability
● Application Scenarios: Suitable for deep-well water extraction, agricultural irrigation, industrial and mining drainage, municipal water supply, and emergency rescue operations.
● Environmental Adaptability: Compatible with various well types, such as steel-cased and earthen wells; supports the use of steel or plastic riser pipes.
5. Safety and Convenience
● Sand-Proof Design: The motor shaft end is fitted with dual oil seals and a sand-slinging ring to effectively prevent sand ingress.
● Easy Installation: No pump house is required; the unit operates while fully submerged, reducing construction costs.
6. Low Maintenance Requirements
● Modular design facilitates disassembly and servicing; the water-lubricated system eliminates the need for external lubrication maintenance.
● Stator windings utilize water-resistant insulation materials, enhancing motor reliability in humid environments.
With its core strengths of high efficiency, durability, and ease of maintenance, the Keda QS Graphite-Sleeve Deep-Well Pump is an ideal solution for deep-well water supply and drainage applications.
