Duplex Stainless Steel Multistage Centrifugal Sea Water Marine Pump
The Duplex stainless steel multistage centrifugal sea water marine pump is designed for high performance and durability in harsh environments. It features a compact structure, low vibration, and high efficiency. The mechanical seal ensures long-lasting operation, while all components that come into contact with the liquid are made of stainless steel for enhanced corrosion resistance.
This pump is especially suitable for low to medium pressure applications. All parts that touch the liquid can be made of stainless steel, making it ideal for corrosive liquids like seawater. For less aggressive liquids such as clean water or similar, cast iron is often used. Cast steel is preferred for mine water with small solid particles due to its wear resistance. Stainless steel (SS) materials are essential for corrosive media, with SS316L being commonly recommended for seawater applications.
 Medium:
♦ Hot and cold clean, non-flammable and non-explosive liquid without solid grain and fibre. If handling explosive liquids, an explosion-proof motor should be selected.
♦ Mineral water, soft water, pure water, mine water, sewage, chemical liquids, and other similar media.
♦ When the density or viscosity of the liquid is higher than water, a motor with higher power should be selected.
 Applications:
♦ Urban water supply and pressure boosting systems
♦ Industrial circulating and processing systems
♦ Boiler water supply, condensing system, high-rise building water supply, or fire fighting system
♦ Water treatment and RO (Reverse Osmosis) systems
♦ Cooling water systems
Electric Motor :
TEFC motor, IEC standard, IP55/IP54/IP23, Class F/B.
Motor bearing: NSK, SKF, common bearings also available as options.
50HZ or 60HZ, 3-phase.
380V/415V/460V/6KV/10KV.
