相较于传统机械轴封式离心泵浦的诸多缺点，例如：机械轴封泄漏造成工安危害与环境污染、马达风扇冷却导致噪音大、联轴器校心不良造成高震动、以及零组件繁杂、润滑油添加、转动元件间隙调整…等因素所导致的高维护成本，Nikkiso 日机装罐式无轴封泵浦可符合API 685 及ATEX/IEC/CNS 规范，拥有许多优势，特别适合用于石化厂内易挥发的流体。
设计有主防漏套及第二层防漏套，可保障工作安全并兼顾环境保护。
藉由操作的液体来冷却马达及润滑轴承，因此噪音小、震动低，并且提高了设备运转的可靠度。
积木块组件设计、无联轴器装置、转动元件少、且不需调整间隙或对心，可大幅降低维修人力与成本。
适用于石化厂内易挥发的流体、炼油、化纤、纺织、钢铁、电厂(包含核能电厂)、面板/半导体之超纯水系统、化学品仓储、海水淡化厂，PCB 厂热媒系统等。
