Vertical Submersible Seawater Pump

Designed for rigorous marine and industrial applications, our Vertical Submersible Seawater Pump offers a space-saving, energy-efficient solution for handling aggressive seawater environments. Unlike traditional horizontal pumps, this vertical design minimizes footprint. Ideal for shipbuilding, offshore platforms, desalination plants, coastal cooling systems, and aquaculture facilities, this pump is engineered to deliver reliable, maintenance-free operation in high-salinity and high-corrosion conditions.

Key Features

1.Superior Corrosion Resistance

All wet components are constructed from Duplex Stainless Steel (Ss316/ss2205) or Nickel-Aluminum-Bronze (NAB).If the sand content is high, special materials can be selected.

2.Centrifugal pump head

Precision-cast impellers and diffuser, optimized via Computational Fluid Dynamics (CFD), deliver high head at low NPSH, ensuring smooth operation even with fluctuating seawater levels.

3.High-Efficiency IP68 / F-Class Motor

Fully sealed, water filled motors (IP68) with Class F or H insulation. Optional winding temperature detectors (PT100) and leak probes are available for enhanced protection.

3.Longer Service Life

Heavy-duty shaft bearing sand advanced mechanical seals ensure dry-run protection and extended mean time between failures .

Technical Specifications

Technical parameters can be customized according to flow rate, head, installation depth, and operating conditions.

FAQ

1. What is a Vertical Submersible Seawater Pump used for?

It is mainly used for seawater intake, marine cooling systems, offshore platforms, desalination plants, and aquaculture water circulation.

2. What material is recommended for seawater pumping?

SS316 is commonly used for normal seawater conditions. Duplex 2205 and 2507 are recommended for higher chloride concentration or offshore environments.

3. Can this pump handle seawater containing sand?

Yes. For seawater containing sand or suspended particles, special wear-resistant materials and customized hydraulic designs are available.

4. What is the maximum installation depth?

The installation depth depends on pump model, motor design, cable length, and project requirements. Please contact our engineers for selection.

5. Can you provide OEM service?

Yes. Aote provides OEM and ODM services including material selection, pump dimensions, voltage, frequency, and cable customization.

6. How do you test each pump before shipment?

Each pump undergoes performance testing including flow, head, insulation, leakage, and vibration inspection.

7. What information is needed for pump quotation?

Please provide:
Flow rate
Head
Seawater temperature
Salinity
Installation depth
Power supply
Material requirements

8. What is the difference between vertical and horizontal seawater pumps?

Vertical submersible pumps require less installation space and are suitable for wells, offshore systems, and seawater intake structures. Horizontal pumps are usually installed in dry locations with more space.
