Stainless steel deep well submersible pumps engineered for seawater applications with flow rates from 5-2000 m³/h and lift capabilities up to 600 meters. These corrosion-resistant pumps deliver reliable performance in demanding marine environments.

Choose the optimal stainless steel grade based on your corrosion requirements:

• Non-corrosive media: Cast iron HT200
• Mild to moderate corrosion: Stainless steel 304
• Strong corrosion resistance: Stainless steel 316/316L

These seawater submersible pumps are ideal for:

• Offshore platform fire-fighting systems
• Aquaculture and mariculture operations
• Seawater desalination plants
• Coastal area water lifting and distribution
• Ground source heat pump systems
• Coastal fountain and water feature applications

• Seawater, alkaline corrosive water, and clean water
• Temperature range: +5°C to +35°C (standard), up to 120°C (high-temperature models)
• Solid content: ≤0.01% by mass
• PH value tolerance: 1-12
