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

DG boiler feed water pump, also known as the feeding pump is a horizontal centrifugal pump used to supply water to steam generators such as boilers. Currently, all boiler feeding pumps are centrifugal pumps, used in fuel and nuclear power plants. DG series is a common horizontal multistage centrifugal pump with a flow rate typically ranging from 10 to 500 m³/h and a head coverage of 100 to 2000 meters, operating at temperatures ≤160°C. This pump model features cast steel or stainless- steel flow components and possesses characteristics such as high efficiency and low net positive suction head. Boiler feed pumps must comply with standards like GB/T 5657 and API 610, along with specialized technical specifications such as JB/T 6614-2025. Performance range (design point) Flow rate Q: 3.75~720 m³/h Head H: 476~985 m Structural characteristics: DG type pump is a horizontal, single-suction, multi-stage segmented centrifugal pump. Both the inlet and outlet of the pump are vertically upward. The tightening bolts connect the suction section, middle section, and discharge section into a single unit. The pump rotor consists of components such as the impeller and balance disk mounted on the shaft. The entire rotor is supported by sliding bearings at both ends of the pump shaft. The bearings are lubricated with oil and cooled by circulating cold water. The axial force of the rotor is balanced by the balance disk. The shaft seal adopts either packing or mechanical sealing. Sealing glands are installed at both ends of the shaft, containing soft packing or mechanical seals. Pressurized water is directed into the sealing glands to provide water sealing and cooling functions. A replaceable bushing is fitted at the shaft seal to protect the pump shaft. The pump is directly driven by the motor through an elastic coupling, and from the motor end, the pump rotates clockwise. The boiler feeding water pump is a horizontal, two-end supported, radially split, radial-flow centrifugal pump used to provide feedwater equivalent to steam discharge for steam generators (such as boilers or nuclear reactors). During the operation of the boiler feedwater pump, it is necessary to ensure a minimum flow rate to prevent damage to the pump caused by vaporization or cavitation due to the increase in medium temperature under low flow conditions. This is usually achieved by installing a minimum flow valve (automatic recirculation valve). The pump can only operate within the specified parameters; It is not allowed to operate for a long time when the outlet valve is closed or the opening is very small; Cannot close the suction valve for operation; The conveying medium must not contain air or gas; Materials that cannot transport particles on the conveyor belt; Before starting, a check is required. Before starting the pump, check the bolts, pipelines, instruments, valves, oil level, and motor direction; Open the suction valve and close the outlet valve when starting, fill the pump with liquid, start the motor, and slowly open the outlet valve after normal operation. During the operation of the pump, it is necessary to regularly monitor the pressure, flow rate, temperature, vibration, and lubrication conditions. The temperature rise of the bearing should not exceed 35 ℃ above the ambient temperature, and the maximum temperature should not exceed 75 ℃. It is necessary to check whether there is balancing liquid flowing out of the balancing device (connected to the suction section through the balancing water pipe). When stopping the pump, the outlet valve should be closed to the minimum flow rate first, then the motor should be stopped, and finally the outlet valve should be closed. After the pump stops steadily, the suction valve should be closed. It is strictly prohibited to close the suction valve first.

Metal or plastic magnetic pump for refrigerant Magnetic pump is mainly composed of pump head (impeller, pump body), outer magnetic steel (active rotor), inner magnetic steel (passive rotor), and isolation sleeve. The electric motor drives the outer magnet to rotate, and because of the effect of the magnetic field, the inner magnet rotates synchronously. Because the inner magnet and impeller are integrated, the impeller also rotates together with the inner magnet to pump liquid. A static isolation/spacer sleeve made of corrosion-resistant and high-strength engineering plastics, stainless steel, and other materials is installed between outer magnetic steel or inner magnetic steel. The conveyed medium is enclosed within the isolation sleeve, thus completely solving the problems of running, emitting, dripping, and leaking that cannot be solved by dynamic seals. The wide application of magnetic pumps in the refrigeration industry 1、 Refrigerant pump The refrigerant pump is an important component of the refrigeration system, and the magnetic pump can effectively meet the pumping needs of the refrigerant. Due to the use of a leak free sealing structure in the magnetic pump, refrigerant leakage is avoided, and the hassle of frequently replacing seals in traditional gas turbine water pumps or mechanical seal pumps is also eliminated. Therefore, the application of magnetic pumps in refrigeration systems is becoming increasingly widespread. 2、 Refrigerated oil circulation pump The refrigeration oil circulation pump is an important component of the refrigeration system, which separates the oil in the liquid refrigerant to avoid affecting the refrigeration effect. Magnetic pumps can meet such specialized applications. Using magnetic pumps can greatly reduce the occupied area of pump rooms, while also achieving precise flow and pressure control. 3、 Cooling water pump Cooling water pumps are mainly used in the cooling circulation water circuit of refrigeration systems. Traditional cooling water pumps usually adopt mechanical seal structures, and problems such as corrosion, corrosion, and leakage of refrigerant during operation can lead to a decrease in pump performance and increase maintenance difficulty. The magnetic pump adopts a leak free sealing structure design, which can avoid such problems and greatly improve performance.

Cooling tower spraying pump In industrial circulating water systems and cooling towers, the spraying pump is a critical component ensuring stable equipment operation. Its primary function is to continuously deliver liquid, maintaining system temperature balance and preventing equipment damage from localized overheating. These pumps typically need to meet requirements such as corrosion resistance, stable flow rate, and moderate energy efficiency to accommodate long-term continuous operation demands. Cooling tower spraying pumps are mostly designed as centrifugal pumps, which operate on the principle of driving the impeller at high speed via an electric motor. This generates centrifugal force, flinging the liquid from the impeller center to the periphery and creating a pressure differential for transportation. The pump features a single-stage enclosed impeller structure with only one impeller and a single-sided suction method, effectively reducing liquid backflow and enhancing transportation efficiency. The pump shaft adopts a side-mounted layout, resulting in a more compact pump body structure, making it suitable for installation in space-constrained scenarios. Closed cooling towers typically use vertical or horizontal centrifugal pumps for the spraying system, with materials such as cast iron, bronze, or stainless steel to accommodate the water quality and corrosiveness of the spraying water Before installation, check the pump body for sealing integrity to prevent leakage during operation. In the initial running phase, monitor the motor temperature and vibration to ensure no abnormal noise. After prolonged use, regularly clean impurities from the impeller and pump chamber to avoid blockages affecting performance. If the transported medium contains particles, it is recommended to install a filter at the pump inlet to extend the equipment's lifespan. Additionally, voltage fluctuations should be controlled within ±10% to prevent motor overload damage.
