3.5SDM Submersible Deep Well Pump For Clean Water

Application

The 3.5SDM Submersible Deep Well Pump is engineered specifically for demanding aquatic environments, excelling in For pumping clean water with sand content less than 150g/m3. This unique anti-sand capability ensures that the internal mechanisms remain free from abrasive jamming, allowing for highly efficient, continuous operation even in challenging water sources. Designed for versatility, this pump serves as a reliable backbone For well pumping, river pumping, farm irrigation, water supply.

Beyond traditional agricultural uses, this model adapts effortlessly to a wide array of commercial and industrial scenarios. It provides consistent pressure for high-rise building water supply systems and maintains the steady flow required for elaborate fountain landscape projects.

• Agricultural & Municipal: Ensures stable water transfer for large-scale farm irrigation and local water supply networks.
• Commercial Landscapes: Delivers the exact pressure needed for continuous fountain and water feature operation.
• Industrial Extraction: Provides a dependable solution for industrial deep well extraction and aquaculture facilities, minimizing downtime.

Operating conditions

To ensure optimal longevity and performance, this submersible pump is calibrated for specific environmental thresholds. It operates flawlessly with a Water temperature up to 35℃ and an Ambient temperature permissible up to 40℃. By utilizing the surrounding fluid to naturally dissipate heat, the system prevents thermal fatigue during extended operational cycles.

The physical dimensions are precision-engineered for narrow boreholes. As a specialized unit, the 3.5SDM Minimum internal diameter of well: 3.5"(90mm) makes it an ideal fit for restrictive drilling sites without sacrificing flow capacity. Furthermore, it is capable of reaching substantial underground aquifers with a Maximum immersion depth:80m. At this extreme depth, the heavy-duty casing withstands immense hydrostatic pressure, ensuring that water extraction remains stable and uninterrupted for deep-source applications.

Motor

Core Construction and Certifications

At the heart of this deep well pump lies a meticulously crafted Rewindable motor, designed to offer long-term reliability and straightforward maintenance. The motor assembly is built with Insulation Class B materials, providing excellent thermal resistance. The fully sealed enclosure boasts a  Protection IP68 rating, completely preventing dust ingress and allowing for continuous, safe underwater submersion.

Premium Materials and Global Standards

Every unit strictly adheres to NEMA dimension standards, guaranteeing universal compatibility and easy integration into existing infrastructure. We elevate the core construction by utilizing a premium stainless steel pump body that feels solid to the touch and actively resists rust in complex water compositions. Internally, pure copper motor coils deliver superior electrical conductivity and a quiet, consistent hum during operation, paired with wear-resistant PPO impellers. To further validate its safety and quality, the pump is backed by international certifications including CE, ISO9001, and CCC, meeting stringent global market entry requirements.
