Key Advantages & Industrial Partner Value
IP68 Fully Submersible Design & Reliable Waterproof Performance
Our 3SP deep well submersible pump features an IP68 fully sealed waterproof structure, compliant with NEMA dimension standards, enabling continuous long-term underwater operation without leakage risk. This eliminates the need for priming and ensures stable performance even in fluctuating water levels, critical for remote well water supply projects.
Sand-Tolerant Construction & Extended Service Life
Full AISI 304 stainless steel impellers, diffusers, and pump body deliver excellent wear resistance for water with up to 0.25% sand content. High-precision ceramic/graphite mechanical seals prevent sand and impurities from entering the motor, reducing maintenance frequency and extending service life for agricultural and mining operators.
Built-In Safety Protection & Stable Operation
The rewindable copper motor is equipped with overheating protection, which automatically shuts down the pump during overload, jamming, or abnormal operation to prevent motor burnout. This feature minimizes unplanned downtime and ensures safe, uninterrupted water supply for commercial and industrial partners.
Compact Structure & Easy Installation
The slim, integrated design fits 3-inch and larger well diameters, making it suitable for narrow boreholes and limited installation spaces. The lightweight construction simplifies transportation and on-site installation, reducing labor costs for engineering contractors working in remote areas.
Application Scenarios
Underground Water Extraction & Domestic Water Supply
The primary application of our underground water extraction pump is for domestic and commercial water supply from deep wells, boreholes, rivers, and reservoirs, delivering reliable clean water for residential communities, rural areas, and remote facilities.
Agricultural Irrigation & Livestock Breeding
Widely used as an agricultural irrigation deep well pump for large-scale farm sprinkler irrigation, drip irrigation, and livestock breeding water supply, ensuring consistent water delivery for crop growth and farm operations.
Mining & Industrial Dewatering
Suitable for mining project dewatering, underground engineering drainage, and industrial water circulation, with durable construction to withstand harsh working conditions in mining and construction sites.
Recreational & Municipal Water Systems
Ideal for swimming pool water circulation, landscape water supply, and municipal greening irrigation systems, providing quiet, efficient water transfer for public and recreational facilities.

FAQ
What is the minimum well diameter required for the 3SP deep well submersible pump?
This pump series is designed for a minimum well internal diameter of 3 inches (75mm). It is also compatible with larger well diameters, with optional accessories available for stable installation in wider boreholes.
Can this pump handle water with sand or solid particles?
The pump is optimized for clean water with a maximum sand content of 0.25% (150g/m³). Higher sand content will accelerate wear of the impeller and seal, so we recommend customized wear-resistant configurations for applications with higher sand content.
Is dry running allowed for this submersible pump?
No. Dry running will cause severe damage to the mechanical seal and motor, and is strictly prohibited. The pump must be fully submerged in water during operation to ensure proper cooling and lubrication.
