Product Description

304SS Submersible Deep Well Pump, 120m³/h Flow, 80m Head Comprehensive Tech Training

In industrial water supply, agricultural irrigation, and food processing sectors, the stability of the water source and the purity of the water quality are paramount. The 304 Stainless Steel Deep Well Submersible Pump (Flow: 120m³/h, Head: 80m) has emerged as the premier solution for deep well extraction, renowned for its exceptional corrosion resistance, high energy efficiency, and compliance with food-grade hygiene standards.

1. Core Material: Why Choose 304 Stainless Steel?

The "heart" and "skeleton" of this submersible pump are crafted entirely from premium 304 stainless steel. This is not merely a material choice; it is a commitment to durability and safety.

• Exceptional Corrosion Resistance: With a chemical composition containing 18% Chromium and 8% Nickel, the material forms a dense, passive chromium oxide layer on the surface. This effectively resists rust and corrosion even in mildly acidic or alkaline environments (pH 4-10), offering a lifespan significantly longer than traditional cast iron pumps.

• Superior Mechanical Properties: Microstructural analysis reveals a uniform austenitic structure. Even under high pressure (compressive strength up to 1.6MPa) or 25% pre-strain, the material maintains excellent toughness and structural integrity, ensuring reliable operation in deep-well high-pressure conditions.

• Food-Grade Hygiene Standards: The surface is smooth, dense, and non-porous, preventing bacterial growth. It fully complies with NSF/ANSI 61 and GB/T 17219 standards, making it the ideal choice for municipal drinking water projects and the food processing industry.

2. Precision Engineering: Built for Efficiency

We focus not only on materials but also on the optimization of every design detail.

1. Full Stainless Steel Body: Robust and durable with high impact resistance.

2. IP68 Submersible Motor: Features F-class insulation and a water-filled design that ensures superior cooling effects, supporting continuous, long-term operation.

3. High-Efficiency Hydraulic Model: Precision-cast stainless steel impellers and diffusers, combined with fluid dynamics optimization, significantly reduce hydraulic losses.

4. Double Mechanical Seal: Utilizes Silicon Carbide and Tungsten Carbide faces, paired with an oil chamber equipped with a leakage detection probe to build a watertight defense system.

5. Integrated Check Valve: Built-in stainless steel check valve effectively mitigates water hammer effects during shutdown, protecting the pipeline system.

4. Industry Case Studies: Proven Performance

From coastal aquaculture to precision pharmaceuticals, this 304SS submersible pump delivers stability in extreme environments.

• Food Processing Plant (Guangdong): After replacing legacy cast iron pumps, the facility eliminated rust contamination issues. The new pumps have run for 24 months without failure, fully meeting HACCP food safety system requirements.

• Seafood Aquaculture Base (Shandong): In a high-salinity environment where standard pumps corrode rapidly, the 304SS pump demonstrated excellent resistance to seawater erosion, drastically reducing equipment replacement frequency.

• Pharmaceutical Manufacturer (Jiangsu): Customized for a purified water system, the pump ensured zero contamination risk, complying with GMP pharmaceutical standards and supporting high-quality drug production.

• Large-Scale Irrigation (Hebei): In a centralized irrigation project covering thousands of acres, the high efficiency of the pump reduced electricity costs by approximately 15%, ensuring reliable water supply during critical crop growth stages.

5. Installation & Maintenance Guide

Proper installation and maintenance are essential to ensuring peak performance.

• Installation Checklist:

  • Verify the well diameter is greater than 150mm (6") and ensure the well pipe is flushed clean.

  • Crucial: For water-filled motors, ensure the motor cavity is filled with clean water before submersion.

  • Use dedicated waterproof cable joints for electrical connections and test insulation resistance.

• Maintenance Schedule:

  • Daily: Monitor current, voltage, and water flow stability.

  • Quarterly: Check the oil level in the oil chamber and test motor insulation resistance (should be >50MΩ).

  • Annually: It is recommended to hoist the pump for a comprehensive inspection and replace mechanical seals or wear parts if necessary.

Conclusion

With a flow rate of 120m³/h and a head of 80m, the 304 Stainless Steel Deep Well Submersible Pump serves as the reliable "heart" of modern industry and agriculture. It combines corrosion resistance, high efficiency, and ease of maintenance to provide you with a secure, clean water supply.
