PBG系列管道式屏蔽泵为立式水泵，电泵有水泵和屏蔽电动机（以下简称电机）两部分组成。水泵部分主要零部件叶轮、泵体、密封环，电机部分主要零部件有定子、转子、屏蔽套、轴承座、轴承、推力盘、冷却管、放气阀等零部件组成。
屏蔽泵电机选用H级绝缘绕组。转子由不锈钢轴和铸铝转子组成。为了防止输送液体进入定子和腐蚀转子，在定子内径及转子表面分别用不锈钢屏蔽套密封。
密封性：泵体法兰与电机法兰连接处，机座与轴承座及定子屏蔽连接处均有耐热O型密封圈密封。
屏蔽泵叶轮悬臂安装在电机转轴上，由键和螺母予以固紧。
润滑与冷却：采用外循环。当泵工作时，由电泵出口处引出少量液体经过冷却管、后轴承与轴颈间隙、定、转子间隙、前轴承与轴颈间隙、叶轮后口环组成一循环回路（单级）、最后一级叶轮进口环组成一循环回路（多级）。
