316L Stainless Steel Seawater Submersible Pump 2.2-410kw High-Lift

This series is designed specifically for harsh marine environments. Utilizing ultra-corrosion-resistant 316L stainless steel and incorporating advanced fluid dynamics optimization technology, it delivers high-lift, long-life, and low-energy submersible pump solutions. Widely used in seawater desalination pretreatment, shipbuilding, offshore platforms, deep-sea mining, geothermal development, and other fields, it is an ideal choice for handling complex corrosive media and high-pressure conditions.

• 316L Stainless Steel: The pump body, impeller, and shaft are all stainless steel, resistant to chloride ion corrosion and suitable for seawater and saline media.
• High-lift Design: Single-stage lifts reach 120 meters, with a maximum total lift of 500 meters, meeting deep-sea water extraction requirements.
• Sealing: IP68-rated, with dual mechanical seals and rubber O-rings, ensures long-term, stable underwater operation.

• Power Range: 15kW-250kW
• Voltage: 380V/660V (customizable)
• Frequency: 50Hz/60Hz
• Head Range: 120-500m
• Flow Range: 10-1200m³/h
• Applicable Media: Seawater, saline liquids (sand content ≤ 2%)
• Material: 316L stainless steel, tin bronze, duplex steel (optional)

• Wear-Resistant Design: The impeller features a three-blade structure and wear-resistant sealing rings. It can pump impurities with a sand content of ≤ 2% (particle size < 3mm), making it suitable for applications such as dock water intake and mine drainage.
• Multi-Voltage Compatibility: Supports a variety of power supply configurations, including 380V/460V/660V/1140V/3300V, and is compatible with both land and marine power systems.
• Extreme Environment Certification: IP68 waterproof rating, ExdⅡBT4 explosion-proof rating, and CCS certification are achieved, ensuring stable operation in temperatures ranging from -20°C to 90°C.
