相較於傳統機械軸封式離心泵浦的諸多缺點，例如：機械軸封洩漏造成工安危害與環境污染、馬達風扇冷卻導致噪音大、聯軸器校心不良造成高震動，以及零組件繁雜、潤滑油添加、轉動元件間隙調整等因素所導致的高維護成本，Nikkiso 日機裝罐式無軸封泵浦可符合 API 685 及 ATEX/IEC/CNS 規範，擁有許多優勢，特別適合用於石化廠內易揮發的流體。
設計有主防漏套及第二層防漏套，可保障工作安全並兼顧環境保護。
藉由操作的液體來冷卻馬達及潤滑軸承，因此噪音小、震動低，並且提高了設備運轉的可靠度。
積木塊組件設計、無聯軸器裝置、轉動元件少、且不需調整間隙或對心，可大幅降低維修人力與成本。
適用於石化廠內輸送的流體（包含熱煤油）、以及煉油、化纖、紡織、鋼鐵、電廠(包含核能電廠)、面板/半導體之超純水系統、化學品倉儲、海水淡化廠，PCB 廠熱媒系統等。
Nikkiso無軸封泵浦有以下主力型式。若以下規格無法符合您的需求，歡迎您與我們聯絡。我們將為您規劃及推薦最適合的產品。
適用於中等溫度、成分乾淨、不易揮發之化學液體。
