Sea water desalination pump The core flow components (impeller, pump casing, shaft, etc.) of seawater desalination pumps are preferably made of duplex stainless steel or super duplex stainless steel to resist corrosion and stress cracking in high chloride environments. Core Recommended Material • Super Duplex Stainless Steel (e.g., 2507/S32750): Currently the mainstream choice for high-pressure pumps in large-scale reverse osmosis seawater desalination systems. With high pitting resistance equivalent number (PREN), it effectively resists corrosion from chloride ions and stress corrosion cracking in seawater, offering superior mechanical strength compared to ordinary stainless steel, making it suitable for high-pressure applications. • Duplex stainless steel (e.g., 2205/S31803): Suitable for booster pumps and transfer pumps in medium-low pressure or pretreatment stages. It offers better cost performance than super duplex steel and significantly outperforms 316L in corrosion resistance, making it a commonly used balanced solution in engineering applications. • Super austenitic stainless steel (e.g., 904L, 6% Mo steel): Used as an alternative in specific highly corrosive or high-temperature applications, offering excellent corrosion resistance but at a high cost, typically employed for critical seals or special components 316/316L stainless steel: Although containing molybdenum element, it has insufficient resistance to pitting and crevice corrosion in long-term seawater environment, and is prone to local corrosion. It is only recommended for short-term, low flow rate or non critical auxiliary pipelines and is not recommended as the main material for core overcurrent components. bronze alloy (such as nickel aluminum bronze): a traditional marine material, but it is susceptible to cavitation corrosion and electrochemical corrosion under continuous operation conditions of seawater desalination, and environmental restrictions have increased. Modern large-scale desalination plants have gradually been phased out. Ordinary carbon steel/cast iron: no anti-corrosion ability, strictly prohibited from direct contact with seawater medium Distinguishing working conditions: The high-pressure pump (RO system core) must use high-grade materials such as 2507; The water intake pump/discharge pump can use 2205. Process control: Duplex stainless steel has extremely high requirements for welding and heat treatment processes, and it is necessary to ensure the balance of ferrite/austenite ratio, otherwise brittle phases may precipitate and cause failure. Non metallic materials: Some seals, bearings, or liners may use special engineering plastics such as carbon fiber reinforced PEEK to assist in corrosion resistance and friction reduction. It is recommended to prioritize API 610 standards material confirmation based on specific pressure levels, seawater temperatures, and project budgets

2BE-type water-ring vacuum pump and compressor is a high-efficiency, energy-saving product developed by our company based on years of scientific research achievements and production experience, combined with advanced technologies from international counterparts. It is typically used to extract gases free of solid particles, insoluble in water, and non-corrosive, thereby creating vacuum and pressure within sealed containers. By altering the sealing material, it can also be employed to extract corrosive gases or utilize corrosive liquids as the working medium. The 2BE-type water-ring vacuum pump is widely applied in industries such as papermaking, chemical, petrochemical, light industry, pharmaceuticals, food, metallurgy, building materials, stone processing, coal washing, mineral beneficiation, and fertilizer production. The 2BE type water-ring vacuum pump adopts a single-stage single-action structural design, featuring advantages such as simple structure, easy maintenance, reliable operation, high efficiency, and energy savings. It can also adapt to harsh working conditions such as large drainage capacity and load impact fluctuations. 　　 We conducted systematic optimization design for key components of the 2BE-type water-ring vacuum pump, such as the distributor plate, impeller, and pump shaft. This simplified the structure and improved performance, achieving energy savings. The impeller features welded construction, with blades formed through one-time stamping and shaping, ensuring rational contour lines. All machining processes are completed, fundamentally resolving dynamic balance issues. The impeller and pump shaft adopt a thermal assembly interference fit, ensuring reliable performance and smooth operation. After welding, the impeller undergoes comprehensive heat treatment, giving the blades excellent toughness. This fundamentally guarantees the blades' impact and bending resistance, enabling the 2BE-type water-ring vacuum pump to adapt to harsh working conditions with load impact fluctuations. The 2BE-type water-ring vacuum pump comes with a built-in air-water separator and multiple discharge ports. The pump cover features an inspection window for the exhaust valve. The clearance between the impeller and the distributor plate is adjusted via the positioning shaft's end covers. It offers convenient installation, simple operation, and easy maintenance.

PWDDFL-type multi-suction head sludge pump features an impeller with single/double flow channels and double/multi-blades, employing high-efficiency, clog-free hydraulic design for excellent flow performance. It boasts a compact structure, small footprint, smooth operation, minimal vibration, high reliability, simple installation, and user-friendly operation. When paired with our company's electrical control cabinet, it enables automatic control functions. In addition to the common traits of centrifugal pumps, the multi-suction head vertical silt-free sludge pump possesses three unique advantages: 1. Multiple Suction Heads. Each pump is equipped with 3 or 4 suction heads, distributed across the center and corners of the sump pit. This design ensures high suction head redundancy, extensive water intake range, and reduced pit sedimentation. 2. Integrated Agitation: A mixer is installed beneath the primary suction head, stirring up settled materials in the pit to effectively prevent clogging and silt accumulation. 3. Self-Supporting Design。 Unlike other vertical sewage pumps that require brackets fixed to pre-embedded supports (which complicates both installation and maintenance), the multi-suction head pump uses its side suction heads as both intake points and structural supports. No additional installation is needed—simply place the pump in the pit and connect the discharge pipe for stable operation, with easy maintenance. This pump is primarily suitable for industries such as power plants, steel mills, coal mines, chemical plants, pharmaceuticals, municipal engineering, construction, hospitals, hotels, seawater drainage, rural biogas tanks, and agricultural irrigation. It can also handle the pumping of sludge, wastewater, urban domestic sewage or rainwater, and clean water containing solid particles or long fibers etc.

Slip on flanges, also called SO flanges, are a popular type of pipe flange designed to accept pipe into the bore/center of the flange for welding around both the Outer Diameter (OD) of the pipe and on the interior side of the connection. Design & Installation Principle The inner diameter of a slip-on flange is slightly larger than the outer diameter of the pipe, allowing the pipe to slip easily into position. After alignment, fillet welds are applied on both sides to secure the connection. This simple installation method reduces fabrication time and overall installation cost, making slip-on flanges a popular choice for large-scale projects. Standards & Size Range Our slip-on flanges are manufactured in accordance with international standards to ensure compatibility with global piping systems: ANSI / ASME B16.5 (NPS 1/2” – 24”) ANSI / ASME B16.47 (Large Diameter Flanges) AWWA C207 (Waterworks Flanges) EN 1092-1 / ISO 7005 (European Standards) Available sizes typically range from DN15 (1/2”) up to DN600 and above, depending on the applicable standard and project requirements.
