PBG系列管道式屏蔽泵為立式水泵，電泵有水泵和屏蔽電動機（以下簡稱電機）兩部分組成。水泵部分主要零部件葉輪、泵體、密封環，電機部分主要零部件有定子、轉子、屏蔽套、軸承座、軸承、推力盤、冷卻管、放氣閥等零部件組成。
屏蔽泵電機選用H級絕緣繞組。轉子由不銹鋼軸和鑄鋁轉子組成。為了防止輸送液體進入定子和腐蝕轉子，在定子內徑及轉子表面分別用不銹鋼屏蔽套密封。
密封性：泵體法蘭與電機法蘭連接處，機座與軸承座及定子屏蔽連接處均有耐熱O型密封圈密封。
屏蔽泵葉輪懸臂安裝在電機轉軸上，由鍵和螺母予以固緊。
潤滑與冷卻：采用外循環。當泵工作時，由電泵出口處引出少量液體經過冷卻管、后軸承與軸頸間隙、定、轉子間隙、前軸承與軸頸間隙、葉輪后口環組成一循環回路（單級）、最后一級葉輪進口環組成一循環回路（多級）。
