Product Introduction The Series is a heavy-duty, horizontal multistage centrifugal pump, engineered specifically for the extreme challenges of high-pressure seawater applications. Constructed from advanced, corrosion-resistant superalloys, this pump is designed to reliably generate the ultra-high pressures required for processes like reverse osmosis desalination. This pump is the robust, high-performance heart of any system that requires moving seawater at high pressure, combining durability with the efficiency needed for energy-intensive operations.
Design Philosophy & Construction The pump is built to withstand the dual attack of high pressure and the severe corrosivity of seawater.
- Superior Corrosion-Resistant Materials: This is the most critical design aspect. All wetted components of the pump are constructed from advanced materials like Duplex Stainless Steel or Super Duplex Stainless Steel. These alloys are specifically chosen for their exceptional resistance to chloride-ion pitting, crevice corrosion, and stress corrosion cracking, which are the primary failure modes for lesser materials in high-pressure seawater.
- Horizontal Multistage Hydraulics: The pump achieves its high-pressure capability through a series of impellers and diffusers arranged sequentially on a robust horizontal shaft. Each stage adds pressure to the seawater, efficiently building up to the very high heads needed for applications like reverse osmosis.
- Robust Ring-Section Casing: The pump’s casing is built in segments (ring sections) that are held together under compression by strong, external tie-rods. This proven, heavy-duty construction is ideal for safely containing the immense pressures of the application and provides excellent mechanical stability.
Key Features & Benefits
- Maximum Resistance to Seawater Corrosion: The Duplex and Super Duplex Stainless Steel construction ensures a long, reliable service life by providing the ultimate protection against the highly corrosive effects of pressurized seawater.
- Ultra-High Pressure for Desalination: The multistage design is specifically engineered to generate the constant, high pressures (55-70 bar / 800-1000 psi) required for Seawater Reverse Osmosis (SWRO).
- High Efficiency at High Pressures: The advanced hydraulic design is optimized to minimize energy consumption, a critical factor in the power-intensive desalination process.
- Durable for Continuous Operation: The heavy-duty construction, robust bearings, and advanced materials are designed for reliable, 24/7 service in critical infrastructure plants.
- Proven Reliability: This design is a proven, trusted solution for major desalination and water injection projects around the globe.
Common Applications The pump is the premier choice for industrial-scale, high-pressure seawater processes:
Offshore Platform Services: Providing high-pressure seawater for various duties on oil and gas production platforms.
Seawater Reverse Osmosis (SWRO): The main high-pressure feed pump in desalination plants, responsible for pushing seawater through the RO membranes to create fresh water.
Seawater Injection: Used in the oil and gas industry to inject high-pressure seawater into oil reservoirs to maintain formation pressure and improve recovery (Enhanced Oil Recovery).
High-Pressure Industrial Cleaning: Powering large-scale cleaning and descaling systems that use seawater as the working fluid.
