Magnetic drive pumps MDE series

Features of MDE series

Strong Corrosion Resistance

Fluoroplastic and fine ceramic are used in the liquid end parts. These materials enable strong acids, strong alkalines, and virtually all chemical solutions to be handled.

High Levels of Durability

The exterior of the pumps is covered with ductile cast iron (FCD400). Ample pressure resistance has been provided in the rear casing through the adoption of a unique shape that prevents the concentration of stress, and a dual structure reinforced with an FRP cover. In addition, the spindle and magnet capsule, which are subject to the repetitive stress of rotational vibration, are made of fluororesin with special metal inserts. These are thus built to withstand sustained operation over an extended period under harsh service conditions.

Compliant with Standards ISO

The basic performance, dimensions, and other particulars of the pumps are in compliance with the international standard (ISO2858, 3661, 5199). They are interchangeable with general-purpose centrifugal pumps.
Note: Model MDE 125-250 is excluded.

Back Pullout Construction

The pumps have back pullout construction, enabling their internals to be inspected or their component parts to be replaced without disconnecting associated piping. Moreover, the simplified construction consisting of unit components makes maintenance and inspection easy.

Examples of applications

• CHEMICALS: Soda industry (manufacture of hydrochloric and hypochlorous acids, as well as their secondary products), manufacture of hydrofluoric acids and fluorides, manufacture of chemical fertilizers, circulation of reaction liquid in gas-absorption towers, oil refining (sulfuric acid), use in waste-acid recovery and regeneration facilities, and transfer and supply of strong acids to tank trucks at general chemical plants
• PHARMACEUTICALS: Manufacture of high purity chemicals for semiconductors, manufacture of agricultural chemicals, use in factories for the synthes is of medicine, and manufacture of chemicals for water treatment
• PLATING:  Recycle filtration of plating liquid for various plating systems
• ELECTRICAL APPLIANCES: Manufacture of electrolytic capacitors (etching of aluminum film), transfer of electrolytic liquid for storage batteries and dry cells, etching of printed wiring boards, and transfer of pure chemicals for semiconductors
• METAL INDUSTRY: Use in alumite treatment facilities, degreasing and pickling at wire elongation plants and steel-rolling mills, use in facilities for the prepainting treatment of vehicles (degreasing and acid washing), and use in factories for the manufacture of titanium oxide, rare-earth elements, etc.
• MINING: Metal smelting (transfer and circulation of electrolytic liquid) and scrubber treatment of waste gases
• FOOD INDUSTRY: Manufacture of monosodium glutamate (hydrochloric acid), refining of edible oils (sulfuric acid), and use in fruit-canning plants (hydrochloric acid)
• WATER TREATMENT: Washing of ion-exchange resins, and use in pure-water production facilities and salt-to-fresh brine distillation facilities
• POLLUTION CONTROL: Charging of wastewater treatment chemicals into injection tanks, collection and transfer of waste liquid, and use in gas adsorption facilities (deodorization equipment, desulfurization of flue gas, etc.)
