By Anhui dragon Valve Co. (http://www.ahjlbf.com/) produced single-stage single-suction IHF fluorine plastic alloy chemical centrifugal pump (referred IHF centrifugal pump) is in accordance with international standards and to integrate non-metallic pumps design and manufacturing process. Pump with metal shell lined with poly FEP (F46), pump cover, impeller and shaft sleeve with metal inserts outsourcing fluorine plastic overall sintering repression, seal with externally mounted advanced bellows mechanical seal, static Choice of 99.9% alumina ceramic ring (or silicon nitride), moving ring with PTFE filler material, its excellent corrosion resistant seal. Pump imports and exports of steel reinforcement to enhance the pump pressure resistance. Actual use shows that the pump has corrosion, wear, high temperature, aging, high mechanical strength, smooth operation, advanced and reasonable structure, reliable sealing performance strict, demolition, easy maintenance, long life and other advantages. Suitable temperature: -50 ℃ ~ 150 ℃, when the temperature exceeds 120 ℃, the pump impeller requires the use of high temperature materials. Suitable for continuous transport any concentration acids, alkalis, organic solvents, strong oxidants such as liquid chemical medium risk when transporting solids content of about 5% liquid corrosive media, the need to support corrosion resistant mechanical seal. If the pump head less demanding conditions, suggested the use of 1450 rev / min low-speed motor, can significantly extend pump life.
