I. Overview: by Anhui dragon Valve Co. (http://www.ahjlbf.com/) produced FSB series of fluorine plastic alloy centrifugal pump can be -80-150 degrees temperature conditions, the long-term transport any concentration a variety of acids, bases, salts, strong oxidants and other corrosive media, the flow part of the shell and all with F46 fluorine alloy, which combines the advantages of a variety of fluorine plastic, with particularly strong resistance to corrosion, and has a high mechanical strength, aging, toxin advantages. The high mechanical strength, reasonable design, compact structure, reliable performance, easy maintenance, smooth flow, high efficiency, saving energy, won the "National Science and Technology Award." Second, use: This product series totaling more than 20 specifications, flow, head wide. Used in petroleum, chemical, pharmaceutical, pesticide, pickling, dyes, paints, metallurgy, papermaking, electroplating, food and other industries transport liquid, put an end to run, run, drip, leak, is ideal for building a modern and civilized factory equipment. Third, the pump seal: The pump uses the most advanced externally mounted PTFE bellows mechanical seal, with multiple layers of protection, extending the service life of mechanical seal, for conveying medium containing impurity particles, can be equipped with cooling water without a single face hard on hard (silicon carbide on silicon carbide) mechanical seals, so users need to consider when selecting the solids content to the media. Fourth, the design features: FSB centrifugal pumps, flow components used in all fluorine plastic alloy, compact structure, simple operation, low prices.
