The 4SP electric submersible deep well pump is specifically engineered For pumping clean water with sand content less than 150g/m3. This precise tolerance ensures that the internal impellers remain protected from excessive abrasion while maintaining optimal fluid transfer rates. Industrial and agricultural operators rely on this unit for a diverse array of demanding environments, appreciating its steady performance and reliable output.


To guarantee continuous operation without thermal overload, this submersible pump is designed to withstand specific environmental thresholds. The durable construction allows it to function effectively even when submerged deep underground, providing a large flow and high head performance while maintaining a remarkably low noise profile that minimizes site disturbance.
| Water Temperature | Water temperature up to 35℃ |
| Ambient Temperature | Ambient temperature permissible up to 40℃ |
| Well Diameter | 4SPM Minimum internal diameter of well: 4"(100mm) |
| Sand Tolerance | Maximum sand content:0.25% |
| Immersion Depth | Maximum immersion depth:80m |
Operating within these parameters ensures that the hydraulic efficiency is maximized when the Maximum immersion depth:80m is utilized, providing sufficient pressure for extensive vertical lifts. By adhering to the 4SPM Minimum internal diameter of well: 4"(100mm) requirement, operators can achieve a secure and stable fit inside standard boreholes. Furthermore, keeping the Maximum sand content:0.25% prevents premature wear on the mechanical components, thereby reducing long-term operational costs and minimizing maintenance downtime.


The driving force behind this deep well equipment is a meticulously engineered motor designed for longevity and consistent power output. Built with a high-strength stainless steel body and a 100% pure copper wire core, the motor offers exceptional resistance to corrosion and rust, significantly extending its lifespan in harsh, submerged environments. The cool touch of the metallic casing and the quiet, steady hum during operation reflect its superior craftsmanship and precise assembly.
Every unit is subjected to rigorous performance and lifespan testing before leaving the facility. The manufacturing process strictly adheres to global quality control protocols, with the entire series achieving recognized certifications including ISO9001, CE, and CCC. This commitment to standardized excellence ensures that the motor operates with optimal electrical efficiency, translating to lower energy consumption and dependable daily operation for the end-user.


Recognizing that different projects require specific configurations, we offer a comprehensive suite of customizable features. Our production lines are highly flexible, fully supporting deep OEM and ODM customization to align with your exact project specifications. We also implement an adaptable Minimum Order Quantity (MOQ) policy, welcoming small-batch trial orders for new partners to evaluate the equipment firsthand before committing to larger procurement volumes.


To ensure that your investment arrives in pristine condition, every submersible pump undergoes a rigorous three-layer packing process. We utilize a combination of heavy-duty nylon wrapping, thickened corrugated cartons, and a sturdy outer wooden box. This reinforced packaging strategy guarantees zero breakage during long-distance ocean freight, protecting the heavy metallic components from moisture, salt air, and physical impact during transit.
Alongside our commitment to stable and punctual delivery schedules, we provide comprehensive after-sales backing. Each unit is covered by a standard 1-year warranty to safeguard your procurement. Furthermore, our dedicated technical team is readily available to supply full-spectrum guidance. This includes step-by-step assistance for initial pump installation procedures, performance testing protocols, and practical troubleshooting, ensuring your fluid management system operates flawlessly from day one.
