Fluorine plastic centrifugal pump seal and the main purpose

Posted by uuuseff on November 18th, 2019

1, Overview: Fluoroplastic centrifugal pump too much knowledge, here to talk about its main seal, the main purpose. Hope to help you. It is designed according to the national standard and is suitable for long-term transportation of various corrosive media of various acids, alkalis and oxidants at any concentration under the temperature of -20 ℃ to 120 ℃. The pump body is made of fluoroplastic (F46) Impeller and pump cover and other overcurrent components are used metal inserts outsourcing fluorine plastic alloy one-time high temperature molding. It can be divided into IHF centrifugal pump and FSB centrifugal pump, a collection of a variety of chemical pump advantages, because the pump body with a metal casing lined with fluorine plastic significantly enhance the mechanical strength and pressure resistance of the pump, the use of the rear door structure, a Internal routine maintenance and replacement of parts can be easily done without the need to disassemble the pump inlet and outlet pipes. The actual use shows that the pump is corrosion-resistant, wear-resistant, high mechanical strength, stable operation, advanced and reasonable structure, reliable sealing performance, easy disassembly and maintenance, long service life and so on. Total product line a total of more than 30 specifications, flow, lift a wide range of users by the majority of welcome. 2, the choice of mechanical seal: The most advanced external PTFE bellows mechanical seal, which is characterized by the pump shaft to compensate for the radial runout, single-ended sealed exterior, easy loading and unloading, intuitive working condition, corrosion-resistant wear Sealing performance, with multi-layer protection, extending the life of the machine seal; for the delivery of particles containing impurities, can be equipped with no cooling water Single-end hard and hard (silicon carbide on silicon carbide) mechanical seal, Acid and other special corrosive media with pressureless sintered silicon carbide seal, so the user selection should take into account the solids content of the medium. 3, Uses: Fluorine plastic centrifugal pump corrosion and wear resistance has been confirmed by the actual use and the majority of users unanimously approved, has been widely used: chemical production of corrosive media transport, ionic membrane caustic soda project Chlorine water wastewater treatment and acidification process, non-ferrous metal smelting electrolyte delivery, pickling process in automobile manufacturing, and pharmaceutical, petroleum, electroplating, dyes, pesticides, paper, food and other industries, is the most popular units welcome One of the pump equipment.
