What material is suitable for pumps used in seawater circulation? Seawater is highly corrosive; 316L stainless steel is an ideal material. If the temperature is not very high, reinforced polyvinyl chloride can be used. Kaiyuan Pump and Valve Co., Ltd. is a manufacturing enterprise specialized in the production of pumps and valves, offering a wide range of products with reliable quality. AFB type corrosion-resistant pump (sea water pump). The AFB type corrosion-resistant pump is a single-stage, single-suction, cantilevered centrifugal pump, with the inlet positioned horizontally and the outlet pointing vertically upward. The pump is mainly composed of components such as the pump body, pump cover, impeller, auxiliary impeller, shaft, seal box, and bracket. The end face where the pump shaft extends is supported by two rolling bearings on a bracket, and the bearings are lubricated with lubricating oil. The AFB type corrosion-resistant pump is suitable for use in various industrial sectors such as chemicals, petroleum, metallurgy, light industry, printing and dyeing, pharmaceuticals, environmental protection, seawater desalination, offshore oil drilling, papermaking, food processing, and power generation, to transport organic or inorganic chemical fluids containing small amounts of solid particles, petroleum products, and corrosive liquids. Product features of the AFB type corrosion-resistant pump (sea water pump): The AFB type corrosion-resistant pump is developed by modifying some of the structural elements and sealing methods of the F type; it uses a secondary impeller-driven sealing device to reduce pressure, and cooling is achieved through an external cooling water pipe. The medium temperature ranges from -20°C to 180°C, with a flow rate of 2–400 m3/h and a head of 10–105 m. ZX type self-priming sea water pump: The ZX type self-priming pump is an energy-saving pump product developed by absorbing, processing, and improving relevant domestic and international technical information. This pump is a self-priming centrifugal pump, featuring advantages such as a compact structure, easy operation, smooth performance, simple maintenance, high efficiency, long service life, and strong self-priming capability. There is no need to install a foot valve in the pipeline; before operation, it is sufficient to ensure that a certain amount of liquid is stored inside the pump. Thus, the piping system was simplified, and working conditions were improved. The ZX type self-priming pump is mainly suitable for applications in urban environmental protection, construction, firefighting, the chemical industry, pharmaceuticals, printing and dyeing, brewing, power generation, electroplating, paper manufacturing, the petroleum industry, mining, and equipment cooling. It is also applicable to clean water, seawater, chemical media liquids with acidity or alkalinity, as well as pasty slurries in general. (The medium has a viscosity of 100 centipoise, with a solid content of up to 30%. ) Features of the ZX type self-priming sea water pump: 1. The ZX type self-priming pump does not require a foot valve to be installed in the pipeline; it only needs to have a certain amount of water stored inside the pump before operation begins. 2. The materials used for the pump can be cast iron, 304, or 316L. 3. The operating temperature range is from -20°C to 120°C; the flow rate ranges from 3.2 to 600 m3/h, the head is between 10 and 80 meters, and the rotation speed is 1450–2900 r/min. FY type submersible pump (sea water pump): The FY type submersible pump is a long-axis vertical centrifugal pump; the parts in contact with the medium are made of cast steel or stainless steel. The submersion depth can range from 0.5m to 6m, depending on customer requirements. Its working parts are submerged in the liquid, which gives it a wide range of applications and high efficiency. It can transport fluid without the need for priming. Since the axial and radial forces generated by the pump’s operation are supported by rolling bearings above the liquid level and sliding bearings below it, the pump operates quietly with no noise. It is thus a high-tech product that offers environmental protection and energy savings. The FY type submersible pump is suitable for use in industries such as chemicals, petroleum, petrochemicals, metallurgy, light industry, printing and dyeing, pharmaceuticals, environmental protection, seawater desalination, offshore oil drilling, papermaking, and food processing, to transport organic or inorganic chemical fluids free of solid particles, petroleum products, and corrosive liquids. Product features of the FY type submersible pump (sea water pump): 1. The FY type submersible pump eliminates the mechanical seal commonly used in other submersible pumps, opting instead for a sealing mechanism with a special design; this solves the problem of wear and frequent maintenance associated with mechanical seals in submersible pumps. The impeller can be of either open or closed type. No sealing is required, making maintenance simple. 2. The medium temperature ranges from -40°C to +180°C. Flow rate: 1.6–400 m3/h, head: 5–80 m, speed: 1450–2900 r/min. Luoyang Napute New Materials Technology Co., Ltd. 13603889856 0379-60679266
