一、概 述
KBU型工程塑料離心泵為臥式、單級、單吸、托架式離心泵,是我廠結(jié)合國內(nèi)外耐腐蝕非金屬離心泵結(jié)構(gòu)的優(yōu)點精心設(shè)計而成。其過流部件采用目前世界上新穎的工程塑料超高分子量聚乙烯(UHMWPE)制作。在耐腐蝕性能上不僅與F4、F46相同,而且耐磨性能、耐沖擊性能。泵的密封根據(jù)不同的工況條件分別采用機械密封、動力密封、自調(diào)式密封多種形式。既可以輸送酸堿清液,也可以輸送含固體顆粒的料漿和含雜質(zhì)的污水。尤其在輸送含細顆粒的腐蝕性液體和輸送*、氟硅酸、磷酸、混酸、電解液、鹽液、稀硫酸、濃堿等方而顯示優(yōu)良的性能。該系列泵適用溫度為-50℃~90℃,更換其它工程塑料(如PVDF、F46)的葉輪、泵體后適用溫度可達120℃。
