LZB  fluoroplastic self-priming pump is designed and manufactured according to international standards and combined with non-metal pump process. The pump body is made of metal shell lined with fluorine plastic, all the flow parts are made of fluorine plastic alloy, the pump cover and impeller are made of metal inserts, and the external bellows are used for shaft seal, the static ring is selected 99.9% alumina ceramic (or silicon carbide), and the dynamic ring is filled with four fluorine materials. It has excellent shoulder resistance and wear resistance. The inlet and outlet are reinforced with cast steel body. To enhance the pressure resistance . The actual use shows that the pump has the advantages of corrosion resistance, wear resistance, high humidity resistance, no aging, high mechanical strength, stable operation, advanced and reasonable structure, strict and reliable sealing performance, easy disassembly and maintenance, long service life and so on.
