LFK series fluorine-lined slurry pump (new product recommended)
Product introduction
After 3 years of research and development, a fluorine-lined pump capable of conveying slurry (liquid containing solid particles) was born. This series of pumps are equipped with semi-open impellers as standard, with front and rear pump covers, and equipped with green ring patented double-end cartridge mechanical seals, suitable for conveying solid particles,

product description








I. Overview
LFK fluorine-lined slurry pump is a high-end corrosion-resistant and wear-resistant centrifugal pump carefully manufactured by Green Ring Company for three years. This series of pumps adopt international new hydraulic model, apply CFD calculation method, and design in combination with relevant standards. Its marking, performance and size are in accordance with ISO2858 standard. It is a multi-resistant pump with strong corrosion resistance, wear resistance, particle resistance and crystal resistance. Functional chemical pump .
Comprehensive introduction
The pump consists of front cover, pump body, impeller, back cover, connecting frame, suspension body, patented cartridge mechanical seal, and other main components. The lining material can be F46, PFA, PVDF, etc. according to working conditions.
When conveying highly abrasive materials, the whole can be lined with fluorocarbon alloy engineering plastics. This material is a proprietary formula material independently developed by Green Ring. It is one of the engineering plastics with the best corrosion resistance and wear resistance at present. Up to 120 degrees.
Pump body introduction: The pump body adopts a front-open door structure design with front cover and rear cover, and the pump suspension part adopts a rear pull-type structure design, which is convenient for users to carry out easier inspection and maintenance.
The impeller adopts a semi-open design and an enlarged flow channel. The fluid flow rate is appropriately reduced and the abrasion resistance is better. It can transport slurry with high viscosity and solid suspended solids. It is not easy to block. Reduce the pressure in the sealed cavity and prevent material particles from entering the sealed cavity to a certain extent;
The low specific speed pump adopts the compound impeller design, which solves the problem that the inlet of the impeller flow channel is not conducive to feeding, reduces the diffusion of the flow channel, effectively prevents the wake flow, greatly improves the flow velocity distribution in the impeller, and avoids The local flow velocity is too fast when conveying the slurry, causing serious wear;
Third, machine seal introduction
The mechanical seal is a core design of the LFK slurry pump. This series of pumps comes standard with a double-end container stationary mechanical seal independently developed by Green Ring Company. The mechanical seal is a special mechanical seal for slurry pumps. Both adopt pressureless sintered silicon carbide, which is resistant to corrosion and abrasion. The medium side mechanical seal adopts a unique static design. The moving ring is built in. The compensation ring is a static ring. The spring does not rotate with the shaft, is relatively static, and is isolated by O-rings. Even if the surrounding area of the dynamic and static ring is completely blocked by the material, it does not affect the spring to make axial compensation at all. The dynamic and static ring is closely fitted, and the specific pressure of the end surface is constant, so that the particles cannot enter the sealed end surface. Truly achieve zero leakage transmission;
The LFK machine seal uses an internal flow design. The centrifugal force generated when the moving ring rotates diffuses into the pump cavity, which effectively prevents the slurry from leaking to the sealed end and greatly reduces the leak rate of the machine seal. Therefore, The mechanical seal can effectively prevent the slurry particles from entering the frictional end surface of the dynamic and static ring, which maximizes the service life and particle resistance of the mechanical seal.
All the components of the machine seal are assembled in a sealed water-sealed box. It is pre-adjusted and compressed before shipment and positioned with a “locating card”. The replacement is simple and quick, reducing the difficulty of maintenance. Compared with the "bulk" mechanical seal, the mechanical seal has absolute precision and longevity advantages. The structural parts of the entire mechanical seal are processed by imported high-precision CNC machine tools. Therefore, the mechanical seal has "acid and alkali resistance" , Wear resistance, high temperature resistance, crystallization resistance, long service life, stable operation and zero leakage, etc.
LFK fluorine-lined slurry pump has unique structural design, flexible material matching, and core-type mechanical seal application. Therefore, the pump is not only resistant to strong acids and alkalis, but also has strong abrasion resistance. It can be widely used in material transportation under severe working conditions such as "strong corrosion, strong abrasion, high temperature, crystallization".
LFK series fluorine-lined slurry pump is the latest product that Green Ring Company has summarized for many years in the manufacture of chemical pumps and undergoes rigorous market research. "And other awards.
LFK fluorine-lined slurry pump is a multifunctional chemical pump. It beats the limitations of traditional fluorine-lined pumps that can only transport clear liquids. It can transport highly corrosive slurry with solid content up to 30%, including easy to crystallize. Material transportation.
Fourth, the main purpose
LFK series fluorine-lined slurry pump's flow parts are completely made of fluoroplastics (the lining layer can be replaced with PFA, U-PE, fluorocarbon composite materials, etc. according to working conditions), which can be widely used in chemical, Non-ferrous metallurgy, pesticides, acid and alkali production, papermaking, pickling process, rare earth separation, electroplating, electronics, chemical foil, acid and alkali removal, etc. are especially suitable for highly corrosive, easily crystallized, solid particulate materials delivery.
