GDL立式多級管道泵適用于高壓運行系統中輸送清水或物理化學性質的液體，如高層建筑給水、鍋爐給水、消防系統等輸送或管道增壓之用。
GDLF型不銹鋼立式多級管道泵采用整體不銹鋼(ZG1Cr18Ni9Ti)材質制造，適用于化工、食品、釀造、制藥、紡織等行業。根據用戶的要求可定制不銹鋼306或316L材質。
GDL立式多級管道離心泵工作條件
a) 本型泵可輸送清水或物理化學性質類似于清水的液體；
b) 溫度范圍：-15℃~+120℃；
c) 工作壓力：最大壓力2.5MPa，即系統壓力=入口壓力+閉閥工作時壓力<2.5MPa；
d) 周圍環境的溫度應低于40℃，相對濕度不超過95%；
e) 輸送含腐蝕性介質及熱液體時，請于訂貨時提出，以便采用特殊材質滿足使用要求。
