The Fire Fighting Submersible Seawater Pump operates by converting electrical energy from the motor into hydraulic energy through the rotating impeller.
When activated, seawater enters the pump suction inlet and is accelerated by the impeller. The hydraulic structure converts velocity energy into pressure energy, delivering high-pressure seawater through the discharge pipeline to firefighting equipment.
The fully submerged installation allows direct seawater intake, reducing suction losses and improving emergency response performance.
The pump is widely used in:
Marine Applications
• Cargo ships
• Offshore supply vessels
• Passenger vessels
• Fishing vessels
Offshore Applications
• Offshore platforms
• Floating production systems
• Marine energy facilities
Industrial Applications
• Coastal power plants
• Seawater firefighting systems
• Large-scale industrial facilities
(1)Inspect appearance, marks and dimensions;
(2)Measure winding and cable insulation resistance;
(3)Confirm correct rotation direction;
(4)No-load test: Monitor current, vibration and noise;
(5)Test flow, head and power;
(6)Check all sealing parts for leakage;
(7)electrical protection functions;
The Fire Fighting Submersible Seawater Pump can be supplied with certification support from major marine classification societies, including:
• CCS (China Classification Society)
• DNV
• ABS
• BV
Certification requirements can be discussed according to specific vessel or offshore project standards.
Metal frame with export wooden box to meet long-distance transportation needs.
These pumps are mainly used for marine fire protection systems, offshore platforms, ships and coastal industrial facilities requiring reliable seawater supply.
Common materials include SS316L, SS2205 duplex stainless steel and SS2507 super duplex stainless steel,Tin-bronze and Al-bronze, selected according to corrosion requirements.
Yes. Aote can customize flow rate, head, voltage, materials and installation dimensions according to customer project requirements.
The pump can support CCS, DNV, ABS and BV classification requirements depending on project specifications.
The submerged structure reduces suction problems, minimizes installation complexity and provides faster response for emergency firefighting systems.
