Sea Water Lift Stainless Steel Submersible Pump

Application of Vertical Multistage Stainless Steel Sea Water Submersible Electric Pump 12"
This high-performance submersible pump is ideal for a wide range of marine and industrial applications, including offshore platform fire suppression systems, thermal cooling, seawater desalination, water lifting operations, coastal fountains, aquaculture, and as a ground source heat pump in coastal environments. Its robust design ensures reliable operation even in the harshest conditions.



Technical Parameters of Vertical Multistage Stainless Steel Sea Water Submersible Electric Pump 12"
- Outlet Diameter: 200mm (8")
- Bolt Quantity: 12 pieces, type 16×60 (8.8)
- Bolt Center Distance: 256mm
- A matching flange is provided (outer diameter: 282mm, inner diameter: 220mm, thickness: 20mm) to ensure easy installation and alignment with the outlet.

Medium Range of Vertical Multistage Stainless Steel Sea Water Submersible Electric Pump 12"
- Suitable for various types of seawater, alkaline corrosive water, clean water, cold water, rainwater, mining gushing water, and drinking water.
- Operating Temperature: +5°C to +100°C
- Solid Content (by mass): ≤0.01%
- The entire unit must be fully submerged in water and installed vertically for optimal performance.




Motor Parameter of Vertical Multistage Stainless Steel Sea Water Submersible Electric Pump 12"
The submersible motor is lubricated by clean water, so it must be filled with clean water before operation. Failure to do so may significantly reduce the motor's lifespan or cause damage. The motor has an IPX8 protection rating, ensuring it can operate safely underwater without risk of water ingress.

Power Source of Vertical Multistage Stainless Steel Sea Water Submersible Electric Pump 12"
- Rated Voltage: 380V / 415V / 460V / 6kV / 10kV
- Frequency: 50Hz / 60Hz
If you require a special voltage or frequency, please inform us in advance to ensure compatibility with your system.
