The RMD/RMI fluorine-lined magnetic pump is a single-suction, single-stage magnetically driven centrifugal pump, characterized by its small footprint, allowing it to be used in various tight spaces. At the same time, its installation and use are also more convenient. The entire pump set features a pull-back design, allowing one person to carry out internal maintenance and part replacement without the need to disconnect the pipes. Power is transmitted using a magnetic coupler, ensuring complete sealing and no leakage. When the motor rotates the outer magnet of the magnetic coupler, magnetic fields pass through the gap and the isolation sleeve to act on the inner magnet, causing the pump rotor to rotate in sync with the motor. Torque is transmitted without any mechanical contact, resulting in safety, reliability, and a long service life. It is a corrosion-resistant pump. Corrosion-resistant pumps are suitable for pumping and circulating/discharging most chemical solutions as well as wastewater containing acidic or alkaline corrosive components. It can transport sulfuric acid, hydrochloric acid, nitric acid, strong alkalis, aqua regia, hydrofluoric acid, strong oxidizing agents, reducing agents, and other highly corrosive fluids of any concentration as long as they contain no suspended particles and their temperature is below 140°C, without suffering any damage. It is the preferred choice for industries such as chemicals, petroleum, refining, nuclear power, chemical products, electroplating, electrolysis, chemical fibers, fertilizers, pharmaceuticals, as well as those dealing with highly toxic, flammable, explosive, and other valuable liquids. Its high-power models are particularly popular among users who require large flow rates and high head pressures. Fluorine-lined magnetic pump.jpg This pump has a very wide range of applications. Made from different materials, it can be used as a chemical pump, corrosion-resistant pump, clean water pump, or sewage pump. When used as chemical process pumps, all the flow-through components are molded from reinforced polypropylene and other materials using fluoroplastics such as F46 and PFA. It can transport sulfuric acid, nitric acid, phosphoric acid, aluminate, oxalic acid, hydrofluoric acid, as well as various organic solvents and oxidizing agents at concentrations below 140°C. When used as corrosion-resistant pumps, the material of the flow-through components is lCr18Ni9Ti and Cr18Ni12M02Ti. When used as a clean water pump, it is made of cast iron. Used as a sewage pump, the fluorinated magnetic pump has its flow-through components made of ultra-high molecular weight polyethylene, which is highly resistant to wear and corrosion, and these components are formed through one-time molding. It can be used for general sewage pumps, as well as for sewage discharge pumps alone and to replace various ceramic pumps. At the customer’s site for fluorinated lining magnetic pumps, these pumps are divided into two types: the RMD direct-connected structure and the RMI mounting frame structure. They consist mainly of a pump body, pump cover, impeller, inner rotor, outer magnetic assembly, stationary and rotating rings, isolation sleeve, mounting frame, etc. Depending on the customer’s requirements, high-temperature insulated magnetic pumps or no-load magnetic pumps can also be provided. The RMD and RMI fluorinated magnetic pumps build on the advantages of IMC magnetic pumps, while also incorporating optimizations and innovations. They feature the following characteristics: 1. The pump body lining, the internal rotor of the impeller, and the isolation sleeve are all manufactured through single-shot molding using pure F46 material, resulting in no impurity formation; this makes them highly suitable for transporting high-purity, highly corrosive chemical liquids ； 2. The pump casing is made of ductile iron; the pump is designed with **standard flanges, offering excellent mechanical strength and the ability to handle heavy pipeline loads ； 3. The linings of the flow-carrying components are made of F46 material, featuring smooth and unobstructed flow channels, excellent hydraulic performance, low hydraulic friction losses, and high efficiency ； 4. The pump shaft, bearing sleeve, and stationary and rotating rings are all made of pressureless sintered silicon carbide, which features high hardness, excellent wear resistance, and superior corrosion resistance ； 5. The unique spiral groove design in the inner bore of the bearing sleeve makes it easier to lubricate the sliding bearing pair and facilitates the dissipation of heat generated by friction during pump operation ； 6. A reinforcement cover made of special material designed for this purpose has been added outside the isolation sleeve, enabling the pump unit to withstand higher system pressures; it also helps to eliminate the heat generated by magnetic eddy currents in the metal sleeve ； 7. The internal and external magnets are made of neodymium-iron-boron and samarium-cobalt materials; the surface magnetic field strength reaches 3600 gauss, enabling efficient transmission of the motor’s torque to the impeller. It prevents slippage even under high-flow conditions, and it also stops the rotor inside the impeller from coming into contact with the rear thrust ring, thus avoiding melting of the fluoroplastic components due to frictional heat. This ensures that the magnetic pump can operate properly in highly corrosive environments. 8. The entire pump unit features a rear-access design, allowing for internal maintenance and part replacement by just one person, without the need to disconnect the pipes. Fluorinated magnetic pumps are widely used in industrial sectors such as chemicals, chlor-alkali, fertilizers, dyes, reagents, pesticides, pharmaceuticals, electroplating, and environmental protection. They are energy-efficient pumps designed for transporting corrosive fluids that do not contain particles. Zhejiang Ruixite is dedicated to providing users with high-quality products suitable for various scenarios and operating conditions, thereby offering them a better experience and service.
