CAO臥式泥漿型磁力泵
CAO Horizontal Slurry Magnetic Driven Pump

  CAO型泵為單級單吸臥式磁力驅(qū)動離心泵，針對含有一定固體顆粒介質(zhì)而研發(fā)的一種新型泥漿型磁力泵，該型泵參照美國石油學會API685及其相關(guān)標準設(shè)計制造，具有全密封、無泄漏、無污染、抗磨損、耐腐蝕能力強、安全可靠、使用壽命長等特 點，可廣泛應(yīng)用于石油化工、精細化工、冶金、電力等行業(yè)。CQAO型泵通過內(nèi)外磁轉(zhuǎn)子耦合傳動，隔離套將內(nèi)磁轉(zhuǎn)子密封在泵腔內(nèi)，運用磁力驅(qū)動技術(shù)與流體動力密封結(jié)合，解決了含固體顆粒介質(zhì)的輸送難題。本系列泵較適用于易結(jié)晶、易沉淀、有懸浮物的介質(zhì)；濃度﹤10%的小的軟固體顆粒介質(zhì)；紙漿、有短纖維狀無磨蝕性、易堵塞的介質(zhì)和氣液混輸（氣體﹤10%）。本系列泵不適用于有磨蝕性的固體硬顆粒，如砂漿、灰渣、礦渣；容易產(chǎn)生纏繞的長纖維物。

CAO horizontal slurry magnetic driven pump is a new type slurry type magnetic driven pump (single stage, single suction horizontal magnetic drive centrifugal pump) developed for media containing certain amount of solid particles. It has been designed and manufactured by referencing API685 and other relevant standards. It features full sealing, no leakage, no pollution, wear resistance, strong resistance to corrosion, high safety, high reliability, and long service life etc. It can be widely used for petrochemical industry, fine chemical industry, metallurgy, and electric power industry etc.
CAO pump is driven by coupled internal and external magnetic rotors. An isolation sleeve seals the internal magnetic rotor inside the pump cavity. Magnetic drive technology has been combined with fluid dynamic seal, solving the difficult problem of conveying media containing solid particles.
This series pumps are better applicable to media subject to crystallization, precipitation, or suspended matter; soft solid particle media of concentration <10%; paper pulp; media containing short fibers (without abrasion) and subject to easy clogging; and mixed gas-liquid media (gas <10%).
This series pumps are not applicable to media containing abrasive hard solid particles, e.g. mortar, clinker, slag, and long fibers subject to easy winding.
