DXB Solutions LLC supplies sea water pumps in UAE for marine, desalination, cooling-water, water treatment, industrial and coastal applications. Seawater pumping requires careful pump selection because the high chloride content of seawater can cause accelerated corrosion when unsuitable materials are used.
Our seawater pump solutions can be selected according to the required flow rate, total dynamic head, seawater temperature, installation conditions and material requirements.
Sea Water End Suction Pumps
End suction seawater pumps can be used for seawater transfer, circulation and cooling applications where the selected materials are compatible with seawater.
These pumps provide a practical centrifugal-pump arrangement for many commercial and industrial installations.
Sea Water Centrifugal Pumps
Centrifugal pumps are widely used for seawater applications requiring continuous movement of relatively large quantities of water.
The correct pump should be selected according to the required flow, head, efficiency and corrosion-resistance requirements.
Sea Water Vertical Pumps
Vertical seawater pumps can be used for suitable intake systems, tanks, pits and installations where the water source is located below the pump-discharge level.
The specific vertical-pump configuration should be selected according to suction conditions, installation depth and required performance.
Sea Water Submersible Pumps
Submersible pumps can be selected for suitable seawater applications where the pump operates directly within the water.
Because the complete pump is exposed to seawater, material compatibility and corrosion resistance are especially important.
Stainless Steel Sea Water Pumps
Stainless steel pumps are commonly considered for corrosive-water applications, but not all grades of stainless steel provide the same resistance to seawater.
For seawater service, material selection should consider chloride concentration, temperature, flow conditions and operating environment. Higher-corrosion-resistance materials may be required for demanding or continuous seawater applications.
This is why a pump should not be selected for seawater simply because it is described as “stainless steel.”
SS316 Sea Water Pumps
AISI 316 / 316L stainless steel pumps offer improved chloride resistance compared with common AISI 304 stainless steel and may be used in certain seawater or saline-water applications.
However, 316 stainless steel is not universally immune to seawater corrosion, particularly under warm, stagnant or high-chloride conditions. More corrosion-resistant materials may be required depending on the application.
Duplex Stainless Steel Sea Water Pumps
For more demanding seawater applications, duplex or super-duplex stainless steels may be specified because of their improved resistance to chloride-induced corrosion compared with conventional stainless-steel grades.
Material selection should be based on the actual water chemistry, temperature, pressure and expected operating conditions.
Bronze Sea Water Pumps
Bronze and suitable marine alloys are also used for seawater pump components in certain marine and industrial applications.
The appropriate material depends on the complete system, including connected piping and other metals, because galvanic corrosion should also be considered when different materials are used together.
Sea Water Pumps for Desalination Plants
Seawater pumps play an important role in desalination and seawater reverse-osmosis systems.
Depending on the process design, pumping equipment may be required for:
Seawater intake → Pretreatment → RO feed → High-pressure process → Transfer → Brine handling
Different stages can require very different pump designs, pressures and materials.
Sea Water Cooling Pumps
Seawater is used as a cooling medium in certain marine, industrial and coastal facilities.
A seawater cooling pump circulates water through the cooling system or heat exchanger. Pump selection should consider continuous operating requirements, corrosion resistance, flow rate, head and water temperature.
Marine Sea Water Pumps
Marine pumping applications can include seawater circulation, cooling, transfer and other onboard or shore-based water-handling systems.
Marine pump selection requires consideration of corrosion resistance as well as reliability, available installation space and operating conditions.
