Product Description: Product OverviewRMD/RMI stainless steel magnetic drive centrifugal pumps (referred to as magnetic pumps) primarily utilize the rotation of the outer magnet in the magnetic coupler. Magnetic lines of force pass through the gap and isolation sleeve to act on the inner magnet, enabling the pump shaft to rotate synchronously with the motor, transmitting torque without contact. At the power input end of the pump shaft, since the liquid is enclosed within the stationary isolation sleeve without dynamic seals, it completely eliminates the unavoidable leakage, dripping, and seepage phenomena in the petrochemical industry, ensuring zero leakage. This type of pump is suitable for conveying toxic, hazardous, flammable, explosive, and valuable liquid media, making it an ideal choice for creating leak-free and pollution-free workshops and factories.Application FieldsThe RMD/RMI series magnetic pumps are suitable for industries such as petroleum, chemical, pharmaceutical, electroplating, environmental protection, food, film processing, water treatment, and national defense. They are ideal equipment for conveying flammable, explosive, volatile, toxic, valuable, and various corrosive liquids.Operating EnvironmentThe RMD/RMI series magnetic pumps primarily feature austenitic stainless steel wetted parts but can also include non-metal linings or thermosetting plastics. These pumps, collectively referred to as metal magnetic pumps, are suitable for conveying liquids without ferromagnetic particles or fibers, with a maximum pressure of 1.6 MPa, temperatures not exceeding 120°C, and viscosity not greater than 30×10⁻⁶ m²/s. For systems with conveying medium pressures exceeding 1.6 MPa, temperatures above 120°C, or requiring insulation measures, our company can provide custom design and manufacturing.Performance Range (Rated Point)Diameter: 32-300 mmFlow rate: 3.2-1000 m³/hHead: 8-150 mTemperature: -20°C to +120°C (customizable up to +120°C to +350°C as needed)Pressure: 0-1.6 MPa (customizable from 1.6-30 MPa as needed) Rotation direction: clockwise from motor perspectivePower: 1.1-315 kWThese are standard parameter ranges. For requirements beyond this range, please contact our company for accurate model selection.Structure DiagramThe RMD/RMI magnetic pump mainly consists of components such as the pump body, impeller, pump shaft, bearings, bearing housing, isolation sleeve, thrust ring, connecting frame, and magnetic drive.Structural Features+ Single-stage, single-suction horizontal centrifugal pump.+ Hydraulic components designed using CFD computational fluid dynamics, featuring wide flow channels, high efficiency, excellent cavitation performance, and low radial force.+ Wetted parts manufactured using precision casting molds, ensuring accurate dimensions, smooth and clean flow channels, and high efficiency.+ Utilizes high-performance, high-temperature-resistant permanent magnet materials to ensure sufficient magnetic torque.+ Low-eddy-current isolation sleeve design, enhancing pump efficiency.+ Modular component design with good interchangeability.+ Sliding bearings and pump shaft made of high-hardness, high-wear-resistant, and high-corrosion-resistant pressureless sintered silicon carbide. Unique dual-bearing alignment structure design combined with hydrodynamic lubrication ensures reliable pump operation and extended bearing lifespan.+ Special lubrication and cooling design: Internal circulation fluid removes heat generated by eddy currents in the isolation sleeve and lubricates sliding bearings, automatically balancing axial forces and ensuring safe pump operation. Rational structural design ensures all internal circulation systems have sufficient pressure and flow for stable pump operation.+ Isolation sleeve capable of fully draining media (during pump shutdown for maintenance) and automatic venting (during priming before startup), typically made of high-quality stainless steel using advanced processes.+ Optional cooling, heating, insulation, or quick-disassembly devices can be added based on operational needs.Model Description:Protection Devices:1. Load controller monitors motor power consumption and can preset a safe operating range. It automatically cuts off power to stop the pump in cases of low load due to cavitation, flow interruption, or magnetic drive slippage, or overload caused by mechanical contact of rotating parts, preventing further damage.2. Temperature sensor indirectly monitors the internal circulation system temperature by detecting the isolation sleeve temperature. If the temperature exceeds the set range, it triggers an alarm or sends an electrical signal to cut off power, protecting the equipment.3. Dual isolation sleeve design allows monitoring of leakage between inner and outer sleeves using leakage detection instruments, ensuring reliable operation even in more demanding conditions. more>

Product Description: O-ring Size Representation MethodFor example: 19*1  S6001l O-ring size representation method: Inner Diameter (ID) × Cross-Section Diameter (CS). For example: O-ring 19*1MM, where 19 represents the inner diameter of the large ring as 19 millimeters, and 1.0 represents the cross-sectional diameter of the rubber ring as 1.0 millimeters.l O-ring product tolerance: Inner diameter 19±0.24       Cross-section diameter 1.0±0.08l O-ring material hardness: Silicone rubber 60 degrees black. Typically, O-ring hardness ranges from 40 to 80 IRHD, but in practice, 70 IRHD is generally more suitable. For silicone rubber, an exception is made, usually using 60 IRHD. Lower hardness facilitates installation but may lead to issues such as peeling, installation damage, extrusion, or even pressure. Higher hardness makes installation less convenient.l O-rings offer excellent sealing performance and high working life. The dynamic pressure sealing working life is 5—10 times higher than conventional rubber sealing products, and can even reach several tens of times. Under certain conditions, they can last as long as the sealed base.l O-rings have low friction resistance, with equal dynamic and static friction forces, which is 1/2—1/4 of the friction force of "0"-shaped rubber rings. This eliminates the "creeping" phenomenon during low-speed and low-pressure movement.l O-rings are highly wear-resistant and feature automatic elastic compensation after sealing surface wear.l O-rings have good self-lubricating properties and can be used for oil-free lubrication sealing.l O-rings have a simple structure and are easy to install. more>

The cleaning cycle is 1-2 hours. If the pH drops below 9 during cleaning, it indicates that the cleaning solution is nearly depleted and should be replenished or replaced immediately.In cases of severe scaling, it may be necessary to extend the cleaning time and soak the membrane overnight. When cleaning severely scaled membranes, it is best to perform a short cycle after soaking.At the end of the cleaning process, it is recommended to rinse the membrane with high-quality water to remove all MPS300 residues.When the system is put back into operation, the first 15-20 minutes of produced water must be discharged, or the duration adjusted based on actual conditions, to ensure no cleaning solution remains.Note: MPS300 may produce foam in the customer's on-site cleaning (CIP) storage tank. To reduce foam generation, move the solution return pipe below the liquid level in the tank.It is recommended to increase the pH and temperature to the maximum limits allowed by the membrane manufacturer to enhance cleaning effectiveness.Physical and Chemical PropertiesAppearanceColorless liquidSpecific Gravity1.18 (20°C)pH (1:45)10-11OdorModerateFreezing Point:＜-5°CPackaging and StorageHigh-strength plastic barrels, 25 kg/barrel or 20 kg/barrelShelf life: 2 yearsSafety and ProtectionWhen handling this product, take labor protection measures.

Product Description: A flameless explosion venting device is a safety apparatus used to protect equipment and personnel. It automatically shuts down equipment or pipelines in the event of an explosion or fire, preventing the spread of flames or the escalation of an explosion. Its working principle involves detecting changes in gas pressure and temperature inside pipelines or equipment to determine whether there is a risk of explosion or fire. If a hazard is confirmed, the device immediately shuts down the equipment or pipeline while releasing pressure to achieve the goal of protecting both equipment and personnel.Flameless Explosion Venting Device for Dust Collectors – Dust Pressure Relief Explosion ProtectorBrief Introduction:1. It consists of two parts: an explosion vent panel and a flame extinguishing module;2. Suitable for flameless venting of dust explosions in indoor equipment. It offers high venting efficiency and is cost-effective;3. Effectively blocks flames and heat, providing a safe environment for equipment, buildings, and personnel. It also collects dust effectively, reducing environmental pollution;4. When used in combination with an isolation valve, it not only prevents pressure waves and flames from propagating to upstream workshop areas but also suppresses secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static activation pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame arrestor material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg·m/s, with effective venting area meeting explosion venting requirements;Product classification: Depending on the application, it can be divided into rectangular flameless explosion venting devices and curved flameless explosion venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclones, dust collectors;Industries: Wood processing, plastics, spray painting, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Flameless Explosion Venting Device for Dust Collectors – Dust Pressure Relief Explosion ProtectorWorking Principle:The flameless venting device consists of two parts—an explosion vent panel and a flame extinguishing module. The explosion vent panel responds to the rapid increase in deflagration pressure, immediately opening to reduce pressure. When the expanding fireball passes through the open vent panel, it is intercepted by the flame extinguishing module. The precision stainless steel mesh, supported by a frame, acts as a three-dimensional flame trap, extinguishing the flame and ensuring it does not propagate, thereby preventing secondary or multiple explosions. The flame extinguishing module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open vent panel.At the same time, pressure waves or noise generated by production equipment are significantly reduced. As flames pass through the mesh flame arrestor element, heat exchange occurs between the element and the flame, rapidly cooling the high-temperature flame, releasing pressure and smoke. Additionally, pressure waves or noise generated by production equipment are reduced.Application Areas:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, machining, and solid waste treatment. Applicable equipment includes cyclones, baghouse dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller grinding systems, and buildings.With increasingly stringent environmental inspections, safety has drawn greater attention. In the past, explosion vent panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, such installations on indoor equipment are not permitted by safety regulations because they endanger surrounding personnel and equipment. The pressure waves and flames from an explosion may cause secondary or multiple explosions, posing risks. Therefore, relying solely on explosion vent panels for dust collectors is not reliable. We recommend using flameless venting + isolation technology (a more economical solution) or suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Blocks the explosion using an isolation valve to prevent flame propagation.Suppression: Detection devices identify sparks and trigger fire suppression systems to instantly extinguish flames, preventing explosions. more>

Combined use with isolation valves not only prevents pressure waves and flames from propagating to upstream workshop production areas but also mitigates secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static opening pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame arrestor material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg*m/s, effective venting area meets explosion venting requirements;Product classification: Based on usage conditions, it can be divided into rectangular flame-free venting devices and curved flame-free venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors;Industries: Wood processing, plastics, spray painting, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Flame-Free Venting Device (Dust Removal Pipeline Explosion Venting and Pressure Relief)Working Principle:The flame-free venting device consists of two parts—an explosion vent panel and a flame arrestor module. The explosion vent panel responds to rapid increases in deflagration pressure, immediately opening to reduce pressure. When the expanding fireball passes through the open vent panel, it is intercepted by the flame arrestor module. The precision stainless steel mesh, supported by a frame, acts as a three-dimensional flame trap, extinguishing the flame and preventing its propagation, thereby avoiding secondary or multiple explosions. The flame arrestor module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open vent panel.Simultaneously, pressure waves or noise generated by production equipment are minimized. As flames pass through the mesh flame arrestor element, heat exchange occurs, rapidly cooling the high-temperature flame, venting pressure and smoke, while also reducing pressure waves or noise from production equipment.Application Fields:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, mechanical processing, and solid waste treatment. Applicable equipment includes cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller grinding, buildings, etc.With increasingly stringent environmental inspections, safety has become a major concern. In the past, explosion vent panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, installing such devices indoors is not permitted by safety regulations, as it endangers surrounding personnel and equipment. Pressure waves and flames from explosions may trigger secondary or multiple explosions, posing risks. Therefore, relying solely on explosion vent panels for dust collectors is unreliable. We recommend using flame-free venting + isolation technology (a cost-effective solution) or suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Prevents flame propagation by using isolation valves to block explosions.Suppression: Detects sparks with sensing devices, then activates fire suppression systems to instantly extinguish flames and prevent explosions. more>
